NOAA-21 First Light Images!
STAR JPSS has produced first light imagery from the recently launched NOAA-21 satellite. The image selected shows the Channel 18 (183 Ghz) Brightness Temperature for the ascending node on November 21-22. ATMS is the first NOAA-21 instrument to be activated.

NOAA-21 CrIS First Light Image - The CrIS sensor provides hyperspectral infrared observations over 2,211 channels with high radiometric and spectral accuracy. The first light image in brightness temperature was captured by the NOAA-21 CrIS sensor at the 1596 cm-1 water vapor channel on February 12, 2023. This image shows the large-scale waves of upper tropospheric water vapor and clouds over the Earth's globe.

The STAR VIIRS SDR team has produced first light imagery from the VIIRS visible bands. The image shows true color imagery from December 5. The VIIRS visible/near infrared bands were the second instrument to be activated, with the VIIRS thermal bands, CRIS, and OMPS to follow in February.

NOAA-21 OMPS NM First Light Image - The Ozone Mapping Profiler Suite (OMPS) instrument on the NOAA-21 satellite acquired its first data on February 18, 2023. This first-light image shows the radiance values for the cloud reflectivity channel on the OMPS Nadir Mapper. The highest radiances are associated with bright cloud tops. The cloud reflectivity channel is one of the five primary channels used to estimate total ozone concentration. The striping pattern is created from the slight differences in the angle of the satellite relative to the incoming energy from the sun.

16 March 2023 - The STAR JPSS SDR teams have released first light imagery for four of its advanced instruments - VIIRS, CRIS, ATMS, and OMPS, aboard NOAA-21. NOAA-21, which is the third satellite in the JPSS series, was launched on November 21, 2022. It will provide continuity for weather forecasters and the broader environmental monitoring community.
VIIRS produces stunning images of the Earth's surface, capturing the beauty and complexity of the planet's natural features in visible and infrared wavelengths. CrIS captures data on atmospheric temperature and moisture as well as the concentrations of various trace gasses important for human health and climate. ATMS collects data on the temperature and moisture of the atmosphere, which is essential for forecasting weather and tracking severe weather events. Finally, OMPS retrieves data on the ozone layer, providing valuable insights into the health of the planet's protective layer. In particular, OMPS features increased resolution
The release of this imagery marked a significant milestone for NOAA-21 and for the scientific community as a whole. The data collected by these instruments will be used to advance our understanding of the Earth's environment and inform policy decisions on issues such as climate change and natural resource management. With this groundbreaking technology at their fingertips, scientists and researchers around the world are poised to make new discoveries and advance our understanding of the world around us.
