Earth scientists from Ames meet with new NASA chief scientist.
The newly appointed NASA chief scientist, Dr. Ellen Stofan, visited Ames on November 21. Her full day of meetings, presentations and tours included interactions with several Earth scientists. During a lunchtime meeting with new career scientists she received short briefings from Matt Johnson (SGE), Kirk Knobelspiesse (SGG) and Ved Chirayath (SG). Johnson described the combination of regional to global models with observations from satellites and UAVs for interdisciplinary studies of climate, atmospheric chemistry and air quality. Knobelspiesse discussed his research on linear polarization in scattered sunlight for insights on atmospheric aerosols, clouds, land surfaces and oceans, and his participation on NASA airborne missions such as the Polarimeter Definition Experiment (PODEX). Ved, who will join the Earth science staff at Ames in early December and is currently completing a PhD in aeronautics and astronautics at Stanford, described new imaging techniques for instruments on airborne and spaceborne platforms. Later in the day Lynn Rothschild (SGE) guided Dr. Stofan through a tour of the synthetic biology lab in building 239.
Modified NASA unmanned airborne system completes flight tests.
Personnel from Ames completed flight tests of a modified Dragon Eye UAS at Lawrence Livermore National Lab (LLNL) on November 14. The tests involved replacing the autopilot and flying the aircraft in remote control mode. The test demonstrated the new control mode could be used safely and effectively. The next step will be to fly multiple aircraft using the same ground control system to demonstrate a new method for systematic atmospheric sampling. The new control process will enable improved tracking and sampling of plumes from volcanoes and other data collection. The test flights, under the auspices of the Airborne Science Program in the Earth Science Division were led by Corey Ippolito (TI).
Ames assisting with Operation Ice Bridge in Antarctica.
Eric Fraim (Ames/UARC) is serving as Digital Camera System (DCS) operator on the NASA P-3 currently operating near McMurdo Station, Antarctica, as part of Operation Ice Bridge, a mission formulated by Ames to provide data continuity for laser altimetry of the Earth's cryosphere between IceSATs 1 & 2. The picture below shows the P-3 at McMurdo with Mt. Erebus, and a steam cloud rising from the volcano, in the background.
NASA ATTREX mission completes instrument integration in preparation for January deployment.
All thirteen instruments for the January deployment of the Airborne Tropical Tropopause Experiment (ATTREX) mission have now been integrated on the Global Hawk UAS at Dryden. The January deployment will be to Guam. ATTREX is an Earth Venture Airborne mission led by Dr. Eric Jensen (SGG). Don Sullivan (SGE) and Dave Jordan (SGG) will return this week from Guam where they have been preparing the mission control center for the deployment. Both will return to Guam next week (after the holiday) to complete the preparations. The schedule to begin ATTREX flights from Guam on or about January 20 remains unchanged.
Paper based on AJAX observations accepted for publication.
A manuscript with results from the Alpha Jet Atmospheric Experiment (AJAX) has been accepted for publication by the peer-review journal Atmospheric Chemistry and Physics. Emma L. Yates et al. “Airborne observations and modeling of springtime stratosphere-to-troposphere transport over California”. Measurements of elevated ozone laminae were observed during two AJAX flights over California as low as 3 km above sea level. The observations were associated with stratosphere-to-troposphere transport. Together with Realtime Air Quality Modeling System (RAQMS) ozone modeling, the airborne measurements provide evidence that the observed ozone laminae influenced surface ozone monitoring sites, with a particular ozone episode exceeding the national ozone standard measured at South Pass, Wyoming. (This paper was reported as being submitted several months ago. It was published first in the letters section of the journal (for comment) and has now been accepted for full publication.)
