Data Sources Summary

FLDAS Forcing Datasets

This page provides information for forcing and land surface datasets used in FLDAS. Tables are given to summarizes attributes of the data and links to original data sources as well as web pages describing additional procedures for data processing and usage.

The FLDAS simulations distributed from NASA GES DISC were forced with RFE2 and CHIRPS rainfall, pared with GDAS and MERRA-2 meteorological forcing respectively.
