AMSUAdvanced Microwave Sounding Unit→
Measurements of the scene radiance, and estimate the global atmospheric temperature and moisture profiles from the surface to the upper stratosphere.
SEM-2Space Environment Monitor-2→
Measurements of Earth's radiation belts and charged particle fluxes at satellite altitude. Provide awareness of solar and terrestrial anomalies and warnings of solar wind occurrences that may damage or impair satellite functionality.
HIRS/4High Resolution Infrared Radiation Sounder →
Estimate the atmosphere's vertical temperature and humidity profiles and the pressure of Earth's surface. Estimate sea surface temperatures, total atmospheric ozone, precipitable water, cloud height, and surface albedo.
Heritage Mission Instruments
SARR and SARPSearch and Rescue Repeater and Processor→
Part of the international Cospas-Sarsat system designed to detect and locate Emergency Locator Transmitters, Emergency Position-Indicating Radio Beacons, and Personal Locator Beacons.
The Advanced Scatterometer →
A radar instrument monitors near-surface wind speed and direction over the global oceans and will follow the development of storms and hurricanes, typhoons and cyclones.
Global Ozone Monitoring Experiment-2 →
A spectrometer that provides the capability to monitor atmospheric ozone, nitrogen dioxide, sulphur dioxide, and other trace gases, in near real-time.
Microwave Humidity Sounder →
Measures profiles of atmospheric humidity as well as cloud liquid water content. It provides qualitative estimates of the precipitation rate.
