NASA Science Community Workshop on Polar Orbiting Infrared and Microwave Sounders
Hyperspectral infrared and microwave sounders, e.g., Atmospheric Infrared Sounder (AIRS), Advanced Microwave Sounding Unit (AMSU) and Infrared Atmospheric Sounding Interferometer (IASI), have become invaluable tools for modern operational numerical weather prediction. The rich information content in their data, along with other IR sounders such as Tropospheric Emission Spectrometer (TES) and Measurement of Pollution in the Troposphere (MOPITT), are becoming increasingly integral to a diverse suite of science investigations including the hydrological cycle, climate variability and feedbacks, atmospheric composition, air quality, and global greenhouse gas distributions.
With the eventual loss of the A-train in conjunction with the increasing need to construct long-term climate-quality data sets, it is vital that continuation of some part of these measurements and their derived products be made by current and planned operational sounders (e.g. the European IASI instrument and the Cross-track Infrared Sounder (CrIS) and the Advanced Technology Microwave Sounder (ATMS),). However, identification of those products critical to the community and an assessment of the expected accuracy and precision for currently planned sounders has not yet been fully explored.
In order to identify paths for continuity in sounder observations and needs for further improvement, NASA sponsored a 2‐day Science Community Workshop on Polar Orbiting IR and MW Sounders.
The workshop was held on November 1st and 2nd 2010 at the Greenbelt Marriott in Greenbelt, Maryland immediately preceding the NASA Sounder Science Team Meeting (November 3rd through 5th at the same venue). The scientific community was invited to participate and share their research and future needs through oral and poster presentations.
