Announcement: North America Land Data Assimilation System Phase 2 (NLDAS-2) hourly products released

North America Land Data Assimilation System Phase 2 (NLDAS-2) hourly products released to the public.

The NASA GSFC Hydrological Sciences Branch and Goddard Earth Sciences Data and Information Service Center (GES DISC) are pleased to announce the release of North America Land Data Assimilation System Phase 2 (NLDAS-2) data products in the Hydrology DISC.

NLDAS-2 products are a 30-year data set (1979-present, in near real-time) of hourly 1/8° surface meteorology and hydrology data over the continuous United States and parts of Canada and Mexico. NLDAS combines observations from many different sources (rain gauges, radar, satellite, model reanalysis) to generate a surface forcing dataset, which is used to drive several different land-surface models. The current data hosted at the GES DISC include both primary and secondary forcing data and Mosaic model outputs.

Users can access the data by searching and downloading via anonymous ftp or through the GES DISC search interface Mirador (http://mirador.gsfc.nasa.gov). Mirador, is an innovative data search engine that makes use of keywords to find data quickly in a Google-like interface. NLDAS data are also provided through a GrADS Data Server (GDS) at http://hydro1.gsfc.nasa.gov/dods/. GDS users can access the data and perform subsetting and analysis operations online. More advanced tools will be provided in later releases, such as spatial and parameter subsetting, data format transformation, and access through the GES DISC online visualization and analysis system *Giovanni*.
