The Cross-track Infrared Sounder (CrIS), which will fly aboard NOAA's Joint Polar Satellite System-1 satellite, has been successfully integrated with the spacecraft. CrIS is the fourth instrument to be integrated on the JPSS-1 spacecraft.

It follows successful integration of the Ozone Mapping and Profiler Suite-Nadir (OMPS-N) instrument, the Clouds and the Earth's Radiant Energy System (CERES), and the Visible Infrared Imaging Radiometer Suite (VIIRS).

CrIS was built by Exelis, in Fort Wayne, Indiana and was delivered to Ball Aerospace & Technologies Corp. in Boulder, Colorado for integration. CrIS provides more accurate, detailed atmospheric temperature and moisture observations essential for weather forecasting. CrIS does this through high performance needed to maintain and improve weather forecast skill out to five-to-seven days in advance of a severe weather event. The sounding accuracy CrIS provides advances the overall capabilities of NOAA operational sounders.

Continuous CrIS global measurements are used by NOAA's National Weather Service to enhance numerical weather prediction model forecasts, aiding short- and long-term weather forecasting. Over longer timescales, they will help improve understanding of climate phenomena, such as El Nino and La Nina and continental transport of greenhouse gases.
