Supporting the Hydrological Sciences Laboratory (HSL)
The Hydrology DISC supports data products generated by GSFC's Hydrological Sciences Branch. Data products from the North America Land Data Assimilation System (NLDAS) and the Global Land Data Assimilation System (GLDAS) can be accessed through anonymous ftp, the Mirador search and access tool or the GrADS Data Server (GDS). NLDAS and GLDAS systems integrate data from multiple space-based Earth observing systems using advanced land surface modeling and assimilation techniques. These products support weather and climate forecast experiments, water resources applications, and water and energy cycle research.
The data are provisional and subject to change as model improvements are implemented and new input data sets become available.
Other atmospheric moisture and precipitation products are available from the AIRS and Precipitation Data and Information Services Centers.
