The VIIRS instrument aboard the new Suomi National Polar-orbiting Partnership (NPP) satellite has a lot of jobs: among them, to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth’s albedo. Now, with the experience of Superstorm Sandy behind it, add tracking power blackouts to the list of tasks for this multifaceted instrument.
VIIRS–or more formally, Visible Infrared Imager Radiometer Suite, is a scanning radiometer that collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. Its low-light sensor–known as the day-night band–can detect light from cities and towns in the absence of clouds. This function recently proved to be highly valuable when NASA’s Short-term Prediction Research and Transition Center used data from VIIRS to assist disaster responses agencies (including FEMA and the U.S. Army Corps of Engineers) in identifying areas that lost power during Superstorm Sandy. Composites of VIIRS images taken before and after Sandy (see below for an example) pinpointed the blackouts.
This is just one example of the promising capabilities of VIIRS; and the growing awareness of these capabilities is why VIIRS is the subject of a town hall meeting on Monday, January 7 (12:15-1:15 p.m., Room 18B) at the AMS Annual Meeting in Austin. Forecasters, meteorologists, and other end users will discuss how they are utilizing the new VIIRS datastream and the critical role it can play in weather forecasting and in improving emergency preparedness and disaster response efforts.
A number of other presentations in Austin will highlight the versatility VIIRS. Jeffrey Hawkins of the Naval Research Laboratory will take an in-depth look at VIIRS’s day-night band and efforts to create enhanced products geared toward various nowcasting applications (e.g., dust enhancement observations, smoke and volcanic ash plumes, cloud properties, tropical cyclone structure, etc.) (Wednesday, 1:30 p.m., Ballroom G). Donald Hillger of NOAA/NESDIS will compare and contrast imagery produced by VIIRS with that from other satellites (Tuesday, 11:45 a.m., Ballroom G). And Jim Biard of the Cooperative Institute for Climate and Satellites will provide details on the VIIRS Climate Raw Data Record (C-RDR), including its contents and structure, its production methods and process, and file access (Wednesday, 11:30 a.m., Ballroom G).
VIIRS is one of five instrument/sensor payloads aboard Suomi-NPP, which is the first of a new breed of satellites that will replace NASA’s Earth Observing System satellites. Launched in October of 2011, the progress and promise of Suomi-NPP and its new data applications will be explored at a town hall meeting on Tuesday (12:15-1:15 p.m.; Ballroom G).
Speaking of Superstorm Sandy, electricity outages, and town hall meetings, there are two related Town Halls of special importance Monday night at the AMS meeting: a wide-ranging meeting on the storm itself (7:30-9:30 p.m.; Ballroom E) and an exploration of the impacts of weather on the electrical grid (Monday, 6:30-8:00 p.m.; Room 14). More on this in future posts on The Front Page.

Wild Weather Comes to NCAR
A new exhibit exploring the power of weather and the stories behind it opened earlier this month at NCAR’s Mesa Lab in Boulder, Colorado. Spark, the group that oversees science education at UCAR, created the exhibit with input from scientists, engineers, designers, and writers.
“Weather is a fascinating topic and it affects us all,” comments Rajul Pandya, director of Spark. “In the new Weather Gallery, visitors can touch clouds, make forecasts, and learn how scientists understand weather using special instruments and computer simulations.”
The NCAR Weather Gallery joins existing exhibits like an eight-foot-tall tornado, a microburst generation tank, and a display that shows current wind speeds measured on top of the building. One of the new features is the interactive, “Tell Your Weather Story,” which gives visitors the opportunity to describe and post their own experiences on weather.
It took about 20 months to plan and develop the exhibit from start to finish. To begin the process, an advisory committee met to decide what topics the exhibit should cover and what they wanted visitors to experience. They came up with a plan that included five content sections and several different ways of delivering information, which included hands-on interactives, large mural photos, panels with pictures and text, and touch screens with games and videos.
Since the exhibit opened on 10 October, the Mesa Lab has had approximately 2,000 visitors, with at least half that number spending time in the exhibits. About 15,000 people a year attend scheduled programs at lab, including 10,000 K-12 students and teachers who take classes and go on tours, as well as 5,000 in special groups and public tours.
“People are really excited about the new exhibit. Visitors love all of the opportunities to play with the hands-on stuff, and it’s been fun to see groups of visitors interacting with each other as they explore different parts of the exhibit,” says Becca Hatheway, NCAR exhibit manager. “UCAR and NCAR staff members are also excited to see something new in this space. I’ve seen just as many staff spending time in the exhibits as I have seen visitors. So I guess we’re all excited to learn more about the weather.” The visitor center at the Mesa Lab is open to the public year round and offers free exhibits about weather and climate, a gallery featuring local artists, an outdoor weather trails, and more. For more information visit the Spark web site.
And speaking of Spark, today (Saturday, 27 October) is UCAR’s Super Science Saturday from 10 a.m. to 4 p.m.–a chance for the whole family to visit the labs and combine science with some Halloween fun. There’s a preview video at the Spark home page:
These Observations Get Our Stamp of Approval
The scientific benefits of Earth observation are well known in the atmospheric sciences. But there’s an artistic side to such observations, too, which is spectacularly depicted in the U.S. Postal Service’s new Earthscapes stamps, released last week in celebration of National Stamp Collecting Month and featuring images shot aloft from a variety of platforms, from a micro-light kite to satellites in space.
The set of 15 different stamps depicts natural, agricultural, and urban scenes from across the country. The Service’s contracted photo editors and researchers culled hundreds of images, which USPS Art Director Howard Paine narrowed down to the final 15. Some photos were taken by people in private planes and helicopters; others were taken by unmanned instruments, including the one below of the volcanic crater of Mount St. Helens in Washington, which was captured in 1999 by NASA’s Landsat 7. Other images in the set include ice breaking off from Alaska’s Bear Glacier, a cherry orchard in Wisconsin, and a cranberry bog in Massachusetts.
Along with the forever stamps, other Earthscapes collectibles for the philatelist include a first-day cover set, a jigsaw puzzle, and an Earthscapes ceremony program.
AMS Dedicates 45 Beacon Room to Joanne Simpson
Last week, AMS held a ceremony at our 45 Beacon Street headquarters in Boston to celebrate the life and accomplishments of pioneer scientist Joanne Simpson. The AMS Council, AMS staff, and members of Joanne’s family gathered to watch the unveiling of her portrait that hangs in what is now “The Simpson Room.” The first woman to ever receive a Ph.D. in meteorology and first female AMS president, Joanne’s numerous contributions to science and the Society were lauded by current AMS President Louis Uccellini and Past President Peggy Lemone:
One of Joanne’s daughters was in attendance and Joanne’s husband, Robert Simpson, and three other children were able to view the ceremony through video conference. Robert had this to say:
On behalf of the Simpson family at large, I want to express our deep appreciation to the Society for its special recognition of Joanne Simpson with this unique posthumous award. All of us appreciate that you chose this unique way of further honoring Joanne. She served AMS nobly and effectively throughout her career—a career distinguished not only by her seminal contributions to tropical meteorology and the general circulation of the globe, but also her dedication to the role of women in science, showering them with encouragement, assistance in their efforts, and championing their struggle for recognition.
Simpson concluded by noting if Joanne had been given a choice she probably would have treasured this recognition by AMS even more than she did her Carl Gustaf Rossby gold medal award.
World Record Temperature Overturned by Climatologists
“I think he read on the wrong side of the [thermometer] scale, and so was off by five degrees of Celsius. If you adjust for that, there was no 136-degree Fahrenheit temperature at El Azizia, Libya, in September 1922. Based on some really involved detective work, [a committee of experts] decided that this reading simply is not valid. It’s not the world’s hottest temperature.”

A Threat to Antarctic Research
Scientific research in Antarctica is approaching a tipping point of its own, with logistical costs overwhelming the budget, according to a new report written by an independent panel commissioned by the White House. The report recommends fundamental changes to the infrastructure of U.S. scientific facilities in Antarctica; otherwise, according to the report, logistics costs will increase “until they altogether squeeze out funding for science.”
The U.S. Antarctic Program (USAP), which is managed by the National Science Foundation (NSF), supports three year-round stations (McMurdo, Palmer, and Amundsen-Scott South Pole), as well as more than 50 field sites a year that are active during the summer months. The report found numerous infrastructure problems at USAP facilities, including:
a warehouse where some areas are avoided because the forklifts fall through the floor; kitchens with no grease traps; outdoor storage of supplies that can only be found by digging through deep piles of snow; gaps so large under doors that the wind blows snow into the buildings; late 1950s International Geophysical Year-era vehicles; antiquated communications; an almost total absence of modern inventory management systems (including the use of bar codes in many cases); indoor storage inefficiently dispersed in more than 20 buildings at McMurdo Station; some 350,000 pounds (159,000 kilograms) of scrap lumber awaiting return to the U.S. for disposal…
In addition, transportation both to and from Antarctica and on the continent has become increasingly problematic. Despite the recent addition of overland traverse vehicles, delivery of supplies to USAP camps remains costly and inefficient. Meanwhile, the U.S. icebreaker fleet currently consists of just one functioning vessel (and that one doesn’t have the capability to break through thick ice). As a result, the United States has been forced to lease icebreakers from other nations–an expensive and unreliable solution.
“We are convinced that if we don’t do something fairly soon, the science will just disappear,” notes Norm Augustine, former chairman and CEO of Lockheed Martin, who led the review panel. “Everything will be hauling people down and back, and doing nothing.”
Almost 90% of the USAP budget is currently spent on transportation, support personnel, and other logistical matters, leaving few resources for actual scientific research. To rectify that situation, the report recommends decreasing the NSF’s budget for Antarctic research by 6% a year for four years and increasing spending on improving the USAP’s infrastructure and logistics by the same amount over the same period. The short-term result will be a hit to the research currently being conducted in Antarctica, but over the long term the proposal should allow such research to continue to take place there. The report also notes additional savings could be achieved by delivering more supplies to the landlocked Amundsen-Scott base at the South Pole by overland traverse instead of cargo flights, and by reducing support personnel at the three USAP bases by 20%. The report also endorses President Obama’s 2013 budget request for the U.S. Coast Guard to begin designing a new icebreaker.
Ultimately, the review panel’s suggestions are about more than just specific numbers and initiatives. They are about a basic change in the way scientific research is conducted in Antarctica. As the report states:
Overcoming these barriers requires a fundamental shift in the manner in which capital projects and major maintenance are planned, budgeted, and funded. Simply working harder doing the same things that have been done in the past will not produce efficiencies of the magnitude needed in the future; not only must change be introduced into how things are done, but what is being done must also be reexamined.

In Case You Didn't Notice, July Was REALLY Hot
This past July was the hottest month on record in U.S. history, according to NOAA’s National Climatic Data Center. The average temperature throughout the contiguous 48 states was 77.6°F, surpassing the previous mark of 77.4°F set in 1936. The first seven months of 2012 were also the hottest on record in the United States, as was the 12-month period of August 2011-July 2012. (Records go back to 1895.)
Interestingly, only one state–Virginia–experienced its hottest July on record, which goes to show how widespread the heat wave was across the country. Thirty-two states had one of their top-10 hottest Julys of all time this year, with seven states recording their second-hottest ever. July temperatures were 3.3°F warmer than the U.S. twentieth-century average for the month, with particularly intense heat in the Plains, the Midwest, and along the Eastern Seaboard.
The five hottest individual months in U.S. history have all been Julys: 2012, 1936, 2006, 2011, and 1934.
In addition to the historic heat, the U.S. Climate Extremes Index, which NOAA uses to calculate temperature anomalies, severe drought, downpours, tropical storms, and hurricanes, was a record-high 37% in July; the previous maximum occurred last July. And the index for the first seven months of the year was 46%, breaking a 78-year-old record. The average index is 20%.

The Rainbow Goes Green
Downtown Omaha, Nebraska, may not be a place you’d expect to see many rainbows, since the state is under an official drought emergency this summer. But art has a way of trumping nature at the Bemis Center for Contemporary Arts. The Rainbow: Certain Principles of Light and Shapes between Forms, an exhibit created by artist Michael Jones McKean, gives residents a glimpse of welcome sights from wetter times. McKean worked with irrigation and rainwater harvesting experts and atmospheric scientists to create the display, in which a dense wall of water shoots up to 100 feet into the air to create a rainbow above the building.
“There are a number of novel aspects of this project,” explains Joseph A. Zehnder, professor and chair of the Department of Atmospheric Sciences at Creighton University, who also served as a technical advisor on rain and wind climatology and on atmospherics optics for the project. “One is that the display is created using harvested rainwater. Local agricultural irrigation and rainwater harvesting companies contributed time and expertise to the project, with the hope of providing a public demonstration of currently available technologies.”
Prior to the opening, a self-contained water harvesting and storage system was built in the Bemis Center. The collected and recaptured storm water is filtered and stored in six above-ground 10,500-gallon water tanks while within the gallery a 60-horsepower pump supplies pressurized water to nine nozzles mounted to the roof. Based on atmospheric conditions, vantage point, available sunlight and the changing angle of the sun in the sky, each rainbow has a singular character and quality.
Zehnder notes that although the basics of rainbows are well understood, there are some complications that arise with providing them on demand. “There are variations in the hue and intensity of the rainbow that are related to the water drop size and density,” he explains. “The drop sizes need to be sufficiently large in order for the internal reflection and refraction of sunlight to occur. Scattering from smaller drops is the wavelength independent Mie scattering so the color separation doesn’t occur.”
McKean began experimenting with manmade rainbows in 2002 and in 2008 started researching the logistics of creating a rainbow over the Bemis Center. In 2010 he started a partial test of the rainbow in Omaha, with the full test last October. “The rainbow is a reminder of a constant universal—something forever, simultaneously contemporary and ancient,” comments McKean. “In the face of our earthbound landscape of shapes and forms, of geologic, evolutionary, archeological timescales, the rainbow is a kind of perfection, our oldest image.”
Even if artists can make their own rainbows, weather still has its say. Because of the dry summer, the Bemis Center is only showing the exhibit on select occasions, with scheduling twenty-four hours in advance. To find out when the rainbow will be on, check here or the Bemis Facebook page. There is also a free mobile app that can be downloaded to Apple and Android phones, which will notify users when the next rainbow will take place and also includes information about the artist and the project.
Illustrating the Weather
The best-selling title in the AMS bookstore is The AMS Weather Book: The Ultimate Guide to America’s Weather, by Jack Williams. Its detailed, full-color illustrations display the unique style that Williams developed during his time at USA Today, the newspaper that perfected the art of the infographic, and those images have proven to be so popular that the AMS has released a CD exclusively featuring them. The Weather, Illustrated: Graphics from The AMS Weather Book (available to order here) features more than 100 of the book’s figures, covering a range of atmospheric phenomena including jet streams, polar air masses,wet and dry microbursts, gravity waves, and Earth’s energy budget. There are also graphics about other aspects of meteorology, such as instrumentation and forecasting. By presenting meteorological concepts with images that are both accessible and stylish, the CD can be a valuable educational tool whether utilized in tandem with the book or on its own.
First Meeting: Atmospheric Biogeoscientists Join Agriculture, Forestry Specialists
The First Conference on Atmospheric Biogeosciences last month in Boston was introduced to broaden the scope of the long-running AMS Conference on Agricultural and Forest Meteorology, now at its 30th meeting. Together, the joint specialty meetings brought in a record number of nearly 200 attendees. According to Ankur Desai, Chair of the AMS Committee on Agricultural and Forest Meteorology, this first joint meeting attracted a whole new audience, with many attendees experiencing their first AMS conference of any kind. Loretta J. Mickley, atmospheric chemist, member of the Board on Atmospheric Biogeosciences, and a conference co-chair, was one of them. “The joint meeting promised to bring together scientists from a range of disciplines,” Mickley comments. “I found the mix of issues enriching.”
The recently initiated AMS Board on Atmospheric Biogeosciences, chaired by Elizabeth Pattey, worked to broaden the focus of the Agricultural and Forest Meteorology meeting, by bringing in the atmospheric chemistry and ecology communities. The meeting featured presentations over four days, covering aspects of the dynamic exchanges occurring at the interface between the atmosphere and the Earth’s surface, such as canopy transport and dispersion, the fate of environmental mercury, and methane emissions from managed and unmanaged landscapes. According to Desai, it turned out to be a great fit. “It was clear from the beginning that there is a natural partnership between the two communities. We sat right at the intersection of where micrometeorology met macroecology.”
Ian Strachan, co-chair of conference and member of the AMS Committee on Agricultural and Forest Meteorology, agrees, noting that by infusing a rich tradition of meetings that goes back to the 1950s with joint sessions from the Board brought these communities together in a way that allowed attendees to explore new connections and avenues of research. Pattey, points out how the smaller venue was ideal for these types of interactions. “By integrating members in a more intimate setting, it opens a new area of direction, allowing collaborations and ideas that are important in establishing stronger ties within and between the two groups,” she comments.
Strachan noted how the sessions also provided an opportunity for students to present their work at a major venue, many for the first time. And according to the chairs, the significant number of talks (~40) and posters (~20) presented by graduate students points to atmospheric biogeosciences as a strong emerging field.
With the positive feedback from attendees, the committee and conference chairs are already discussing another joint meeting. “We plan to continue the tradition from here, bringing in scientists from even more disciplines to add to the diversity of research that was presented at this meeting,” concludes Desai.
