About ASDC

The Mission of the Atmospheric Science Data Center (ASDC) is to be a leading provider of atmospheric science data products and services to the science community through agility, innovation, and technical excellence.
The ASDC is in the Science Directorate located at the NASA Langley Research Center (LaRC), in Hampton, Virginia. The Science Directorate's Climate Science Branch, Atmospheric Composition Branch, and Chemistry and Dynamics Branch work with ASDC to study changes in the Earth and its atmosphere. Data products translate those findings into meaningful knowledge that inspires action by scientists, educators, decision makers, and the public. The ASDC supports over 60 projects and provides access to more than 1000 archived collections. These data sets were created from satellite measurements, field experiments, and modeled data products. The ASDC projects focus on the Earth science disciplines Radiation Budget, Clouds, Aerosols, and Tropospheric Composition.
