AIRS data contributed to these significant findings in weather and weather forecasting science.
AIRS radiances are shown to add skill to short-range weather forecasts over a relatively data-rich area. Principal Component Analysis can be used to compress the observational information content contained in the AIRS channels to a few leading principal components. Adaptive thinning of AIRS radiances is shown to substantially improve tropical cyclone representation in a global data assimilation and forecast system.

4-D assimilation of observations from the major humidity observing systems show improvements in simulated wind and temperature fields. AIRS is shown to have an especially significant impact in simulations of the upper troposphere.

A novel technique is introduced for detection of fog/low cloud using AIRS data. The use of AIRS profiles above the surface level provides surface-based CAPE values that are very similar to those computed from Vaisala radiosondes. Use of AIRS temperature and moisture retrievals for assessing environmental drivers of severe convective storms is enhanced by a method combining soundings with trajectory calculation. AIRS data is used to calculate stability indices that inform about the triggering of extreme rainfall events in the Indian region.

The assimilation of AIRS derived temperature profiles in partially cloud contaminated areas can significantly increase weather forecast skill in a global model and forecasting system.

Assimilating even small amounts of AIRS data improves forecast significantly: Less than 1% of AIRS spectra extends the NCEP global 6-day forecast by 6 hours in both hemispheres. AIRS data are now used routinely by major weather forecast centers around the world, including NCEP (US) and ECMWF (Europe).
