For the first time ever, measurements from NASA Earth-observing research satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

Instruments on NASA's Terra and Aqua satellites were watching as Hurricane Lane -- a category 2 storm as of Friday, Aug. 24 -- made its way toward Hawaii.

Terra at AGU

Terra and her instruments made an appearance in many of the presentations at the American Geophysical Union’s 46th annual Fall Meeting held December 9th – 13th. Scientists, researchers, students and educators gathered to present groundbreaking research and connect with colleagues.

The presentations showcased the versatility and interconnectedness of the instrument suite onboard Terra.

The presentation, Evaluating MOPITT and ACE Upper-Tropospheric Carbon Monoxide Retrievals with HIPPO In-Situ Measurements showed how MOPITT CO levels were validated and contrasted by the Fourier Transform Spectrometer on board the Atmospheric Chemistry Experiment (ACE-FTS), from the Canadian Space Agency and the Quantum Cascade Laser Spectrometer on the HIAPER Pole to Pole Observations experiment (HIPPO-QCLS).

In Comparing Land Surface and Air Temperatures of Urban Heat Islands Over the Contiguous USA the research team overlaid the National Land Cover Database Impervious Surface Area map over the local air temperatures from the Global Historical Climatology Network station distribution map, identifying over 300 urban settlements and comparing local air temperatures versus the land surface temperatures at night and at midday. They found that the observed temperature change was evident in both sets of data, however the magnitude differed.

Assessment of Urbanization Impact on the Continental US Surface Climate showcased the assessment of interactions between urban and different vegetation classes to understand vegetation control on urband heat islands hourly and seasonal dynamics.

NASA and U.S. Geological Survey Long-Term Archive for the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) outlines plans for archiving ASTER data through the US Geological Survey.
These were only a few of the presentations at AGU.  To attend virtual sessions on demand, search the poster and presentation archive and learn more about how Terra is impacting Earth science visit the AGU fall meeting website.
