Common Types of Satellite Sensors in Remote Sensing

Sensor/Satellite Nature Sensor Type Main Agency Core Features Main Applications
SMMR Sensor Passive Microwave Radiometer NASA Early microwave radiometer, historical data source Sea ice, SST, soil moisture (early)
AMSR-E Sensor Passive Microwave Radiometer JAXA/NASA Successor to SMMR, multi-frequency Precipitation, water vapor, SST, soil moisture, snow water equivalent
AMSR-2 Sensor Passive Microwave Radiometer JAXA Follow-up model to AMSR-E, added C-band Same as AMSR-E, data continuity
SMOS Satellite L-band Passive Microwave Radiometer ESA First L-band microwave radiometer, uses synthetic aperture technology Soil moisture, ocean salinity
SMAP Satellite L-band Active Radar + Passive Radiometer NASA Ideal L-band radar + radiometer combination (radar has failed) Soil moisture (global gold standard), freeze-thaw state
Sentinel-1 Satellite series (including A, B, C) C-band Synthetic Aperture Radar ESA C-band SAR, dual-polarization, high resolution, short revisit period Surface deformation, flood monitoring, sea ice, ship detection
MODIS Sensor Optical Imaging Spectrometer NASA Multi-band “spectrometer”, wide-field imaging Vegetation, clouds, aerosols, fire points, surface temperature, etc.
