Where is the latest real-time NLDAS forcing and model data?
A. The real-time NLDAS Phase 2 (NLDAS-2) forcing and model output data is currently in production at NOAA/NCEP/EMC. Automated scripts and programs gather and process the data needed to generate the NLDAS-2 forcing datasets. These scripts/programs run once per day, and update one day’s worth (typically 12Z to 12Z) of forcing. This forcing data is then used to drive the various land-surface models to produce the model output. Scripts archive the data at the NASA GES DISC, as well as at the NCEP/EMC realtime NLDAS ftp site. The very latest available data can be found at either of the previous two links. The data is generally available around 2-5 days behind the current date. The model data may be delayed another day, as an entire day’s worth of forcing is needed for the model simulations. Also, the GDS site may be behind by another couple days, as the updated index file is generated. Occasionally, problems with the data used to create NLDAS-2 forcing and/or disk/computer issues will cause
