NDVI - Normalized Difference Vegetation Index (NDVI) is a simple optical indicator that can be used to analyze remote sensing measurements and assess whether or not the target being observed contains live green vegetation.

NLDAS - North American Land Data Assimilation System (NLDAS) provides a model-generated forcing data set.

NMRI - Normalized Microwave Reflection Index (NMRI) is a GPS-derived vegetation product generated using normalized mp1rms GPS engineering data.

SWE - Snow Water Equivalent (SWE) is a measurement of the amount of water contained in snow pack. It can be considered as the depth of water that would theoretically result if the whole snow pack instantaneously melts. Snow Water Equivalent is the product of snow depth and snow density. It is usually presented in units of either kg m^-2 or m.

VSM - Volumetric Soil Moisture (VSM) in a soil (also called the volume wetness or volume fraction of soil water) represents the fraction of the total volume of soil that is occupied by the water contained in the soil. It is usually presented as a percentage.
