Investigating LEO Sounder Retrieval Product Variations at GEO Temporal and Spatial Resolution

The Cross-track Infrared Sounder (CrIS) instrument, 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 channels. These data can be used to produce high vertical resolution temperature and humidity profiles. The Advanced Baseline Imager (ABI) instrument, onboard the Geostationary Operational Environmental Satellite (GOES)- R series satellites in geostationary Earth orbit (GEO), is a 16 spectral band (with 10 in the infrared) radiometer providing high temporal and spatial resolution radiance measurements and imagery used for monitoring the Earth’s weather and environment. Here we utilize a data fusion method (developed and previously demonstrated at UW-Madison) to construct high vertical resolution CrIS temperature and humidity retrievals at ABI high spatial and temporal resolution. A time series of these products - constructed between LEO sounder overpasses at GEO imager collection intervals - is discussed and presented.
