MODIS, or the Moderate Resolution Imaging Spectroradiometer, is a key instrument aboard NASA's Terra and Aqua satellites. It captures data about the Earth's surface, atmosphere, and oceans, providing valuable information for climate research, land use, and natural disaster monitoring. Launched in 1999, MODIS collects images in 36 spectral bands, allowing scientists to study various phenomena, such as vegetation growth, ocean temperatures, and air quality. Its data is crucial for understanding environmental changes and supporting global efforts in managing natural resources and responding to climate change.
