Abstract
The Crosstalk Infrared Sounder (CrIS) is one of the key sensors now under developed for the National Polar-orbiting Operational Environmental Satellite System program, which is the follow-on to the current DMSP and POES meteorological satellite systems. CrIS is a interferometric sounding sensor which accurately measures upwelling earth radiances at very high spectral resolution, and uses this data to construct vertical profiles of atmospheric temperature, moisture and pressure. The purpose of this paper is to describe the CrIS system design, discuss key trade studies that led to selection of the design, discuss risk reduction demonstrations that were performed to confirm the readiness of the technologies used in the CrIS design, and summarize the key performance capabilities of the CrIS system.
