Washington DC (SPX) Feb 14, 2012
With missions scheduled throughout the year, 2012 is shaping up to be an extraordinary time for NASA's Airborne Science Program and Earth system science research. Multiple aircraft and specialized instruments will operate in the United States, Europe, Asia and South America this year in support of studies conducted by NASA and the Earth science community, improving scientists' understanding of our planet.
The program maintains a fleet of highly modified aircraft and specialized instruments that can be deployed all over the world for Earth science missions. Researchers use these aircraft and sensors to obtain high-resolution measurements of local phenomena and processes, such as ice sheet thicknesses, precipitation and air quality.
These measurements are often combined with global satellite observations and ground sampling to better model and understand the complete Earth system. The Airborne Science Program and flight campaigns play a key role in the development of both hardware and algorithms for future satellite missions.
The aircraft provide scientists with access to unique capabilities, including high-altitude and long-duration flights, and the ability to fly large payloads and multiple instruments to nearly anywhere at any time.
NASA's Airborne Science aircraft and sensors offer the science community the ability to collect data from Earth's surface to 70,000 feet in altitude. These unique assets add another research dimension to ground and satellite measurements.
"NASA's Airborne Science support of the Earth system science community will be exceptional in 2012," said Randy Albertson, NASA Airborne Science deputy program director.
"Not only is the program on track to exceed the 2011 record of 2,600 hours flying science missions, the growth in new sensor integrations means NASA is well poised to conduct more accurate and complex airborne science in the future."
Below are descriptions and links to more information about NASA's 2012 airborne science missions:
Snowfall in Canada
GPM, due to launch in 2013, will set a new standard for precipitation measurements from space, providing next-generation observations of worldwide rain and snow every three hours.
Falling snow is critically important in terms of freshwater resources, atmospheric water and energy cycles, and ecosystems. The GCPEx mission is using instrumented aircraft - the NASA DC-8, NASA-funded University of North Dakota Cessna Citation, and a Canadian National Research Council Convair 580 - for flights over sensors located in and around the Environment Centre for Atmospheric Research Experiments in Egbert, Ontario.
Synthetic Aperture Radar
The G-III returned to Hawaii in January for a third study of volcanoes, including the Kilauea volcano on the Big Island, intended to help scientists better understand processes occurring under Earth's surface.
The UAVSAR imaged the surface deformation caused by the 2010 Mayor-Cucapah earthquake in Baja California, Mexico. Flights were flown from the Dryden Aircraft Operations Facility in Palmdale, Calif., between late January and early February. This study will be repeated in May, July and November.
The sensor will gather data about volcanoes and glaciers during a June deployment to Iceland. The return flight to Palmdale, Calif., will include imaging of the BP oil spill area of the Gulf Coast.
Volcanoes in Alaska, including the Aleutian Island chain, and the Cascade Range of California, Oregon and Washington will be the focus of an August study.
A second G-III is being fitted with the UAVSAR this year to support subsurface and subcanopy soil moisture measurements for the AirMOSS mission.
LIDAR Study of Greenland's Ice
MABEL is a primary sensor candidate for NASA's Ice, Cloud, Land Elevation Satellite-2 (ICESat-2) mission scheduled to launch in 2016. An ER-2 based in Iceland will carry the sensor to altitudes of 65,000 feet, gathering algorithm development data that may allow ICESat-2 to make more precise measurements of global ice. The timing of this mission coincides with the deployment of NASA's P-3B to Greenland for Operation IceBridge.
Two IceBridge deployments are planned for 2012. The Arctic deployment, based in Thule and Kangerlussuaq, Greenland, and Fairbanks, Alaska, will occur March through May and use NASA's P-3B airborne laboratory and NASA's B-200. The Antarctic deployment, based in Punta Arenas, Chile, will use NASA's DC-8 airborne laboratory in October and November.
Arctic Carbon Measurements
Surface Water and Ocean Topography
Gathering data off the coast of California, the Ka-band radar interferometer will help the science team determine the kinetic energy of the ocean circulation and how the ocean uptake of heat and carbon is being transferred into the atmosphere to verify its effects on climate change.
The sensor will also collect hydrology measurements of the storage changes in terrestrial surface water bodies, soil content depending on seasonal changes, and river discharges into large bodies of water like the ocean. The interferometer will be mounted in a NASA King Air B200.
Clouds and Chemistry
North American Ecosystem Soil Measurements
The June mission will use the extensive ground, tower and aircraft measurements to validate model estimates.
AirMoss will use an airborne ultra-high frequency synthetic aperture radar capable of penetrating through substantial vegetation canopies and soil to depths down to 4 feet (1.2 meters). For this mission, NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, in P-band configuration will be mounted in a pod and flown on a NASA G-III.
Student Airborne Research Program
Thirty-two undergraduate and graduate students from across the United States will participate in this NASA research mission. Using NASA's P-3B airborne laboratory, students will measure pollution in the Los Angeles basin and California's Central Valley, evapotranspiration from agricultural crops in the San Joaquin Valley, and study ocean biology along the California coast. In addition to airborne data collection, students will take measurements at field sites.
Soil Moisture Research fro SMAP
Knowledge gained from this research will help improve the soil moisture retrieval algorithms to be used for NASA's Soil Moisture Active Passive, or SMAP, satellite mission planned for launch in 2014. Two aircraft will fly in the field campaign during June and July.
A NASA G-III will fly from a deployment base in Grand Forks, N.D., and will carry the Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, mounted in a pod under the aircraft. The second aircraft, a DHC-6 Twin Otter, will carry the PALS, or Passive Active L- and S-band Sensor, a combined polarimetric radiometer and radar sharing an array antenna.
Southeast Asia Emissions Survey
The NASA DC-8 airborne laboratory will provide observations from near the surface to an altitude of more than 7 miles (12 kilometers). A NASA ER-2 will provide high-altitude observations reaching into the lower stratosphere as well as important remote sensing connecting satellites with data collected from lower flying aircraft and surface sites.
The National Science Foundation Gulfstream V aircraft will investigate chemical transport processes in the 7 to 8.5 mile (12 to14 kilometer) altitude range. Finally, Thailand's Bureau of Royal Rainmaking will provide a King Air Super 350, which will measure cloud and aerosol properties from the surface up to 5.8 miles (10 kilometers) altitude.
NASA Hurricane Studies
Visible and Infrared Imaging Spectrometer Research
Flights as part of an integrated response to extreme dust deposition to the snow cover of the Colorado River basin will focus on areas in Colorado, Utah and Arizona. A Twin Otter will also flyover the Colorado Basin for this research and a comparison of data gathered by the ER-2.
The next-generation AVIRIS-NG sensor will collect data for missions to include a study of carbon assimilation and the health of Florida mangrove forests. Flown on the contracted Twin Otter, the various flights will take place during April and May and again in July and August. The Rocky Mountains of Colorado and the Sierra Nevada range of California will be studied for snowpack.
The spectrometer will collect data on the production and changes of chlorophyll following BP oil spill hydrologic remediation of Bald Cypress swamps along the Gulf Coast of Texas, Louisiana and Florida. Another investigation will quantify the forest biomass and carbon stocks of New York state.
AVIRIS will explore the fuel consumption and carbon cycling in northern peatland ecosystems in California. The states of Massachusetts, New Hampshire and Minnesota are targets of an investigation to quantify uncertainties in interpreting the relationship between hyperspectral data and leaf biochemical elements.
