NLDAS-2 release announcement

[David Mocko]

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 1/8th-degree 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*.
