NLDAS is one of the inputs to the QuickDRI drought index

A LIS blog post was recently published describing the new QuickDRI drought index.

The Quick Drought Response Index was designed to provide monitoring of rapidly-changing drought conditions.

NLDAS-2 monthly soil moisture anomalies are one of the inputs to this weekly operational drought index.

LDAS datasets are available from the NASA GES DISC

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) provides access to LDAS datasets using multiple methods, including HTTPS, GDS, and the ability to subset spatially, temporally, and/or by variable:

These datasets are also available via Giovanni. Giovanni is an online application developed by the GES DISC that allows researchers to rapidly explore data, so that spatial-temporal variability, anomalous conditions, and patterns of interest can be directly and easily analyzed online before optionally downloading the data. Supported download formats include NetCDF, GeoTIFF, and KMZ.
