The Cross-track Infrared Sounder (CrIS) is a Michelson interferometer instrument onboard the NPP (NPOSS Preparatory Project) satellite, scheduled to launch on October 25, 2011. The health of the instrument after launch will be monitored and checked with the Web-based trending/monitoring subsystem, developed as part of the Integrated Calibration and Validation System (ICVS) at the Center for Satellite Applications and Research (STAR), the science arm of the National Environmental Satellite, Data and Information Service (NESDIS). Many instrument parameters and status flags, including the temperature of the internal calibration target, laser wavelength drifting, fringe count error, noise equivalent difference radiance (NEdN) and etc, are monitored.. Daily, monthly and annual statistical descriptions on these parameters are also provided. The CrIS trending/monitoring system has been tested with data collected during the offline thermal vacuum (TVAC) tests and near real-time proxy data derived from IASI.
