The Cross-track Infrared Sounder (CrIS), onboard the Suomi NPP and JPSS-1 satellites in low Earth orbit (LEO), is a high spectral resolution interferometer capable of providing very accurate infrared radiance measurements using more than one thousand three hundred channels at 12 hour temporal resolution. These data can be used to produce high vertical resolution temperature and humidity profiles. The Advanced Baseline Imager (ABI), onboard the Geostationary Operational Environmental Satellite (GOES)- R series satellites in geostationary Earth orbit (GEO), is a 16 spectral band (10 infrared) radiometer providing high spatial resolution radiance measurements and imagery at as high as 5 minute temporal resolution used for monitoring Earth’s weather. A retrieval product with the high vertical resolution from CrIS and high horizontal and temporal resolution would aid in identifying small scale atmospheric features, especially low level moisture. Here we utilize a data fusion method (developed and previously demonstrated at UW-Madison) to construct high vertical, horizontal and temporal resolution temperature and humidity retrievals along with case studies and sonde validation statistics.
