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 meterological forcings are spatialy disagregated in the LIS core software using bilinear interpolation.
** daily rainfall inputs are temporally disagregated with LDT software, matching the rainfall distrubution specified in the meterological forcing
