Abstract
The hyper-spectral radiances collected from the Cross-track Infrared Sounder (CrIS) on Suomi National Polar-orbiting Partnership Satellite (S-NPP) have been in operation for several years. How to catch up the instrumental status together with the calibration data product quality in a real-time mode is a big challenge, considering the huge data volume. We developed a robust system called the CrIS Integrated Cal/Val System (ICVS) to monitor and analyze the operational CrIS instrumental status and radiance data quality at the National Oceanic and Atmospheric Administration (NOAA) Center for Satellite Applications and Research (STAR).
CrIS ICVS is a software package including several parts: an interface to grab real-time CrIS instrument and calibration data from the Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE), a backend processing module to decode/archive/plot the real-time data and send out warning messages whenever anomalies are found, and a frontend web site to display the results.
The CrIS ICVS system has been in use since the beginning of the mission. It has helped us identify a lot of issues, covering a wide range of scopes, including spacecraft maneuvers, instrumental anomalies, calibration algorithm bugs, data transportation rate issues, manual and automatic procedure anomalies in the ground system, and etc.
