Crustal Dynamics Data Information System (CDDIS) - The Crustal Dynamics Data Information System (CDDIS) supports data archiving and distribution activities for the space geodesy and geodynamics community. The main objectives of the system are to store space geodesy and geodynamics related data products in a central data bank, to maintain information about the archival of these data, and to disseminate these data and information in a timely manner to NASA investigators and cooperating institutions. The CDDIS staff and computer facility are located at NASA GSFC in Greenbelt, MD and is part of the Solar System Exploration Division within the Sciences and Exploration Directorate.

DAAC Alliance - The NASA Distributed Active Archive Centers (DAACs) are the data management and user services branches of NASA's Earth Observing System Data and Information System (EOSDIS). The DAACs process, archive, document, and distribute data from NASA's past and current Earth science research satellites and field measurement programs. The DAACs were established in the early 1990s, and each DAAC serves a specific science discipline.

ECS Data Handling System - The EDHS contains a collection of documents related to the EOSDIS Core System (ECS) project, part of NASA's Earth Science Enterprise program. This collection includes Contract
Data Requirements List Items (CDRLs), White Papers, Technical Papers, and other ECS-generated documents. The collection is broken into many catalogs, as well as, a collection of
milestone review and workshop presentations.

SeaWiFS Project Homepage - The purpose of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Project is to provide quantitative data on global ocean
bio-optical properties to the Earth science community. Subtle changes in ocean color signify various types and quantities of
marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications. The
SeaWiFS Project will develop and operate a research data system that will process, calibrate, validate, archive and distribute data
received from an Earth-orbiting ocean color sensor.

TRMM Science Data and Information System (TSDIS) - The real-time processing and post-processing of the TRMM science data is performed by the TRMM Science Data and Information System (TSDIS). Working with
the TRMM principal investigators and science algorithm developers, TSDIS maintains the operational science data processing system and ensures the timely
processing of all TRMM science instrument data. During routine operations, raw instrument data is received in near real-time by TSDIS and then processed by the
first tier of science algorithms to produce calibrated, swath-level instrument data. Using this calibrated, swath-level instrument data, the second tier of algorithms are
used to compute geophysical parameters, such as precipitation rate, also at the swath-level resolution. At the final stage of TSDIS processings, the third tier
algorithms produce gridded geophysical parameters from the first- and second-tier instrument data. All TRMM products are archived and distributed by the Goddard
Distributed Active Archive Center (DAAC). For further information concerning TSDIS operations go to ths TSDIS homepage.
