All JPSS satellites have the following five state-of-the-art instruments:

• The Clouds and the Earth’s Radiant Energy System (CERES), which measures reflected sunlight and thermal radiation emitted by the Earth, creating a long-term dataset of Earth’s radiation budget critical for monitoring climate change.
• The Advanced Technology Microwave Sounder (ATMS), which provides atmospheric temperature and moisture for operational weather and climate applications.
• The Cross-track Infrared Sounder (CrIS), which provides more accurate, detailed atmospheric temperature and moisture observations for weather and climate applications.
• The Visible Infrared Imaging Radiometer Suite (VIIRS), which collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.
• The Ozone Mapping and Profiler Suite (OMPS), which tracks the health of the ozone layer and measures the concentration of ozone in the Earth’s atmosphere.
