The distributed/disseminated JPSS data are available as Temperature Data Records (TDRs), Sensor Data Records (SDRs), and Environmental Data Records (EDRs). Raw Data Records (RDRs) refer to the raw data generated by sensors on the satellites. Science algorithms that perform calibration and geolocation are applied on the RDRs to produce SDRs and TDRs. EDRs are geophysical parameters derived by applying retrieval algorithms on the SDRs. EDR products provide global measurements of such quantities as sea surface temperature, ocean color, ozone and trace gases, aerosols, clouds, temperature and moisture profiles, wind speeds, land surface properties, and snow and ice cover, etc.
