The Hydrology DISC portal enables access to hourly, monthly, and monthly climatology NLDAS datasets via ftp, GDS, Mirador, and Giovanni (hourly, monthly, and monthly climatology). Users can also perform subsetting and analysis operations without first downloading the data. All NLDAS datasets are now available to be downloaded in NetCDF format (as well as in the native GRIB-1 format). Phase 1 forcing, Phase 2 primary and secondary forcing, Phase 2 Mosaic, and Phase 2 Noah datasets are available. Please see the NLDAS-1 README and NLDAS-2 README files for details about the creation and content of these datasets, as well as the FAQ.
Users of NLDAS datasets are encouraged to join the LDAS mailing list for updates on new data releases, new data services, data reprocessing, and data delays or outages.
Numerous NLDAS Phase 2 articles have been recently published; please check the NLDAS publications page for the article links.
NLDAS datasets were used to compare winter 2011-2012 with winter 2010-2011 for snow cover and surface temperature. A poster depicting extreme weather/climate events over North America during 2011 was presented at the AGU Chapman conference. NLDAS datasets were used to illustrate the precipitation and soil moisture along the east coast of the U.S. following the passage of Hurricane Irene and of Tropical Storm Lee, as well as the intensity of the heat wave in the central U.S. during July 2011. NLDAS datasets were used to examine the cold spring of 2013 over the United States.
NLDAS precipitation datasets were used to study the diurnal cycle of summertime precipitation. Here are links to a news story and a science focus article describing the research. The full journal article was published in Geophysical Research Letters.
The near real-time NLDAS drought monitor is now located at NOAA/NCEP/EMC.
