NLDAS Phase 2 model output (hourly and monthly) for the Mosaic, Noah, and VIC LSMs can be downloaded from the GES DISC. NLDAS-2 SAC data will also be added in the near future.
NLDAS-2 Mosaic, Noah, SAC, and VIC data are also available at the NOAA/NCEP/EMC NLDAS ftp servers. Note that all data from EMC is hourly only; no monthly data is available from EMC. Also, please see this FAQ/answer describing the differences between the datasets available from the NASA GES DISC and from EMC.
