NEO - NASA Earth ObservationsHere you can browse and download imagery of satellite data from NASA's constellation of Earth Observing System satellites. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats including JPEG, PNG, Google Earth, and GeoTIFF.
NEO provides the ability for users to download CSV (comma separated values) and floating point GEOTiff files for datasets. The data values included in these files, and additionally used in the data analysis component, are only approximations based upon the scaled range of the original source data. As such, these values are a few generations removed from the original data and while they may be useful for basic analysis and trend determination, they should not be treated as scientific absolutes. For more scientifically rigorous data, please see either the "download data" or data provider links on the respective dataset page.
