warn_icon.gif IMPORTANT MESSAGE Jul 24, 2015    Why do my Data Holdings look different?    

Accessing your data through the GES DISC web site may seem a little unfamiliar to you to these days, but we can assure you, your data is all still available. The location of the data in the online archive has not changed.

The GES DISC has implemented a new interactive interface to make finding data easier than ever. We've added features like searching by keywords, filtering by criteria such as measurements, processing level and spatial resolution, and sortable data columns so now you can fine tune your search results. To get you started we put together a Help document to introduce you to the new interface. If you have any questions about the new design please contact us using the Feedback link in the upper right-hand corner or contact the GES DISC Help Desk by sending email to gsfc-help-disc@lists.nasa.gov.

Welcome to the NASA Data Center for Aerosol Data & Information Web Site at the Goddard Earth Sciences Data and Information Services Center (GES DISC). The purpose of this on-line information center is to enhance the support services we provide to our aerosol research and application community. We've provided a number of resources here to help you in your research and application.

This page is the result of the NASA GES DISC's ongoing effort to create a "One Stop Web Portal" to provide quick, convenient and easy access to aerosol data and information for the research and science education communities.

At this portal, we have tried to accumulate, integrate and provide fast access the aerosol measurements from the various satellite, ground-based and other platforms. We have also included some simple analysis and visualization tools for aerosol data from some of the NASA satellite missions.

Aerosols are one of the greatest sources of uncertainty in climate modeling. Aerosols vary in time and space and can lead to variations in cloud microphysics, which could impact cloud radiative properties and climate. The aerosol products are used to study aerosol climatology, sources and sinks of specific aerosol types (e.g., sulfates and biomass-burning aerosol), interaction of aerosols with clouds, and atmospheric corrections of remotely sensed surface reflectance over the land.

This page is organized to help you find aerosol related data and information quickly and easily.
