Earth Science Data



Earth Observing System Data and Information System (EOSDIS)

Earth Observing System Data and Information System

The Earth Observing System Data and Information System (EOSDIS) is a major core capability within NASA’s Earth Science Data Systems Program. EOSDIS ingests, processes, archives and distributes data from a large number of Earth observing satellites. EOSDIS consists of a set of processing facilities and Earth Science Data Centers distributed across the United States and serves hundreds of thousands of users around the world, providing hundreds of millions of data files each year covering many Earth science disciplines.

CloudSat Data Processing Center

CloudSat Standard Data Products are distributed by the CloudSat Data Processing Center, located at the Cooperative Institute for Research in the Atmosphere at Colorado State University in Fort Collins. The CloudSat mission was selected as a NASA Earth System Science Pathfinder satellite mission in 1999 to provide observations necessary to advance our understanding of cloud abundance, distribution, structure, and radiative properties. CloudSat was co-manifested with the CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) satellite aboard a Delta II rocket for its launch on 28 April 2006. In a series of maneuvers, CloudSat and CALIPSO joined the A-Train constellation of satellites.

Laboratory for Atmospheric and Space Physics (LASP)

Interactive Solar Irradiance Data Center

The Solar Radiation and Climate Experiment SORCE is a NASA-sponsored satellite mission that is providing state-of-the-art measurements of incoming x-ray, ultraviolet, visible, near-infrared, and total solar radiation. The measurements provided by SORCE specifically address long-term climate change, natural variability and enhanced climate prediction, and atmospheric ozone and UV-B radiation. These measurements are critical to studies of the Sun; its effect on our Earth system; and its influence on humankind. The LASP Interactive Solar Irradiance Data Center provides a variety of solar irradiance datasets, including daily measurements, reference spectra, composite time series, and model results.

Precipitation Processing System (PPS)

The Tropical Rainfall Measuring Mission (TRMM) data are generated by the Precipitation Processing System (PPS). PPS is responsible for processing, analyzing, and archiving data from the current TRMM mission as well as the upcoming Global Precipitation Mission(GPM). PPS also provides validation data from multiple TRMM ground radar sites. The data products are available to the science community and the general public from the PPS online FTP archive.
