Welcome to the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC). We are one of twelve NASA Science Mission Directorate (SMD) Data Centers that provide Earth science data, information, and services to research scientists, applications scientists, applications users, and students. The GES DISC is the home (archive) of NASA Precipitation
, as well as Atmospheric Composition and Dynamics
remote sensing data and information. The DISC also houses the Modern Era Retrospective-Analysis for Research and Applications (MERRA) data assimilation datasets (generated by GSFC’s Global Modeling and Assimilation Office), and the North American Land Data Assimilation System (NLDAS) and Global Land Data Assimilation System (GLDAS) data products (both generated by GSFC's Hydrological Sciences Branch).
The GES DISC is located at Goddard Space Flight Center, in Greenbelt, Maryland.
In recent years, the GES DISC has further enhanced its information services through the development of tools and services that promote easier use and usability of Earth science data and information. As the data and information management needs of science researchers have become more sophisticated, we have been able to take advantage of maturing information technologies to develop and implement tools and services that help science researchers extract the information they seek from the data they work with. This too is our goal.
As you visit our Web pages, I hope you will find the data, information and services you are looking for. And also (hopefully), services that make it easier to meet your data and information needs. For example:
- We are continuously enhancing data and information exploration and access and have, in fact, been making great strides in understanding how to – and implementing ways to – bring heterogeneous Earth science data sets together. This has lead us to providing insights into the important topics of data inter-comparison, data bias analysis, and data quality checking. Services to check out: Data Quality Screening Service, AeroStat
- Have you tried Giovanni yet? This data analysis and visualization tool has become extremely popular in allowing research communities to create time series plots, latitude/longitude graphics, and atmospheric depth plots (just to name a few) without having to download any data.
- Multi-dataset systems such as MAIRS, NEESPI and A-Train Data Depot also make it easy for data users to find and extract information from heterogeneous and distributed datasets.
- Mirador is our rather simple-to-use data search tool that allows you to find data by keyword, project, or science area (and measurement). Mirador is a good place to start your data search.
- Cross data center services are beginning to emerge with deployment of Simple Subset Wizard, an easy way to locate and subset data residing at various data centers. We plan to further this data access model, because, after all, locating data and services across the 12 NASA data centers should not be a deterrent.
While at the GES DISC web site, you will find links to our collaborators, other NASA data centers, the Instrument Teams that have worked hard to acquire, process, and validate the data, and NASA Federation of Earth Science Information Partners – all of which can provide additional Earth science data and information to you.
As always, OUR NUMBER ONE GOAL is to serve your Earth science data and information needs. I have been at the GES DISC since 1998, and this is (simply) what the GES DISC staff has always done! However, I believe we can always improve.
If you cannot find what you are looking for, or you have suggestions on how we can improve our services (tools), PLEASE let us know
Thank you for visiting.
