Instruments were flown for imaging and measurement of the atmosphere of Earth, its surface, and cloud cover, including Earth radiation, atmospheric ozone, aerosol distribution, sea surface temperature, vertical temperature and water profiles in the troposphere and stratosphere; measurement of proton and electron flux at orbit altitude, and remote platform data collection, and for SARSAT.
Devices were employed to capture images and collect data on the Earth's atmosphere, land, and clouds, encompassing radiation, ozone, aerosols, surface temperatures, and atmospheric profiles in various layers; they also monitored cosmic particles, gathered remote data, and facilitated SARSAT operations.
