Earth Observation Satellites: Sensors and Applications

This lecture covers the details about Landsat 7 and Landsat 8 satellites, including their launch dates, spectral bands, spatial resolutions, and applications in Earth observation. It also introduces the Sentinel series satellites, such as Sentinel-1, Sentinel-2, and Sentinel-3, focusing on their specifications and applications in monitoring sea ice, glaciers, and marine environments. The lecture further discusses the Sentinel-4 mission, which monitors air quality trace gases and aerosols in geostationary orbit. Additionally, it explores the Global Ecosystem Dynamics Investigation (GEDI) Lidar mission, highlighting its applications in measuring forest canopy height, carbon sinks, and surface elevation changes.
