Introduction
NASA Earth Observation Missions
- CLARREO Pathfinder: Measures reflected solar light and energy to improve the accuracy of climate data collected by other satellite missions.
- CYGNSS: A constellation of seven satellites that analyze Global Navigation Satellite System signals as they reflect off the ocean surface.
- GEDI: The first laser-based instrument designed to generate 3-D maps of Earth's forests, measuring canopy height, branch density, and leaf spacing.
- Landsat Satellites: Monitor land surface changes, including glacier retreat, urban expansion, natural disasters (floods/droughts), and agricultural/forestry shifts.
- Sentinel-6 Michael Freilich: Focuses on ocean circulation and global sea level rise, while also collecting atmospheric data to enhance weather and climate forecasting.
