The World Data Center for Remote Sensing of the Atmosphere (WDC-RSAT) offers scientists and the general public free and simplified access (in the sense of a “one-stop shop”) to a continuously growing collection of atmosphere-related satellite-based data sets and services.

The Goddard Earth Sciences Data and Information Services Center (GES DISC), one of NASA's Earth Science Data Centers, offers data and information related to Precipitation, Atmospheric Chemistry and Dynamics and related disciplines. The GES DISC Giovanni tool is a Web-based application developed that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data.

DataFed is a web services infrastructure developed by the Center for Air Pollution Impact and Trend Analysis at Washington University in St. Louis that is dedicated to air quality that provides mechanisms for accessing distributed datasets, data processing for filtering, aggregation, and fusion, and data browsing and visualization. DataFed implements GEOSS principles for sharing data and is an integral part of the GEOSS air quality community. Data and services from Giovanni and VIEWS-TSS are bi-directionally interoperable with DataFed, meaning that data served by DataFed are accessible through Giovanni and VIEWS-TSS and data served by Giovanni and VIEWS-TSS are accessible through DataFed. DataFed is used by researchers and managers in applications such as exception air pollution event analysis, long range transport assessment and source apportionment studies.

Global Change Master Directory (GCMD)
NASA's Global Change Master Directory (GCMD) aims to enable users to locate and obtain access to Earth science data sets and services relevant to global change and Earth science research. The GCMD database holds more than 30,000 descriptions of Earth science data sets, services and ancillary descriptions covering all aspects of Earth and environmental sciences.

The purpose of the Global Earth Observation System of Systems is to achieve comprehensive, coordinated and sustained observations of the Earth system, in order to improve monitoring of the state of the Earth, increase understanding of Earth processes, and enhance prediction of the behavior of the Earth system. GEOSS will be a global, flexible network of content providers linking together existing and planned observing systems around the world.
