The NASA GES DISC (NASA Goddard Earth Sciences Data and Information Services Center) has announced the availability of a new climate radiance data set we developed at UMBC called CHIRP, which stands for the Climate Hyperspectral InfraRed Product. This data release was annoucned at https://disc.gsfc.nasa.gov/information/data-release?title=Data%20Release%20for%20Climate%20Hyperspectral%20Infrared%20Radiance%20Product%20(CHIRP)%20Level%201%20products.
CHIRP provides a homogenous time series of the earth's infrared emission starting in 2002 that is scheduled to continue through the 2040 time frame using the NASA AQUA Atmospheric InfRared Sounder (AIRS) sounder, followed by a series of five Cross-Track Infrared Sounder (CrIS) series of operational infrared sounders, two of which are presently in orbit. CHIRP modifies the instrument spectral responses to a common spectral response, and removes radiometric calibration differences among these instruments in order to provide a climate-quality radiance data set for climate monitoring of atmospheric temperature and humidity profiles, surface temperature, ozone, other minor gases, and long-wave cloud forcings.
