FLDAS Specifications

FLDAS currently can run with the following specifications and improvements such as additional datasets (forcing and near surface), new land surface models, and algorithms are ongoing in the project.

*coarser scale meteorological forcing are spatially disaggregated in the LIS core software using bilinear interpolation.
** daily rainfall inputs are temporally disaggregated with LDT software, matching the rainfall distribution specified in the meteorological forcing
