EcoSAR is an advanced airborne polarimetric and interferometric P-band (435 MHz) SAR instrument in development at NASA/Goddard Space Flight Center through the 2010 ESTO Instrument Incubator Program (IIP). The aim of EcoSAR is to provide two- and three dimensional fine scale measurements of terrestrial ecosystem structure and biomass.

G-LiHT enables data fusion studies by providing coincident data in time and space, and provides fine-scale (1 m) observations over large areas that are needed in many ecosystem studies.

The Snow Water Equivalent Synthetic Aperture Radar and Radiometer (SWESARR) is a new instrument designed to measure the water content in a snowpack. The instrument, developed at NASA’s Goddard Space Flight Center, uses active and passive microwave sensors to map the radio frequency emissions of the snowpack, which can then be turned into a measurement of snow water equivalent.
