Remote sensing offers powerful tools for ecology. Synthetic aperture radar (SAR) is particularly effective for land-cover classification, measurements of woody plant biomass, determining wetland inundation, and monitoring of crops. SAR bounces a radar signal off the Earth's surface to detect physical properties. Unlike optical technology, SAR can "see" through darkness, clouds, and rain.
Soil Moisture Active Passive See SMAP
- Learn about NASA's SMAP mission.
Wetlands See Wetlands MEaSUREs
- Discover ASF SAR DAAC's wetlands imagery, maps, and animations.
Terrestrial Ecology See SAR Data for Terrestrial Ecologists
- 100 SAR images for about 50 research locations.
- Research locations selected for presence of micrometeorological sensors known as flux towers.
- Because the towers chosen have geospatial data, researchers can validate SAR results against existing data.
