GLAS provided elevation data for determining ice sheet mass balance, global topography and vegetation data, and cloud property information.
GLM detects and maps total lightning and reveals the extent of lightning flashes and the distance these flashes travel.
GEDI is a full-waveform lidar that makes detailed measurements of the 3D structure of Earth's surface.
GMI is a radiometer that is sensitive to microwave energy emitted from or affected by precipitation types including rain, snow, ice, water vapor, and mixed precipitation.
GRACE and GRACE-FO missions consist of two identical satellites that act in unison as the primary instrument to provide data about changes in Earth's gravity field.
