Modeled daily land and snow conditions, High Mountain Asia

High Mountain Asia Daily 0.05 x 0.05 deg Noah-MP Land Surface Model Reanalysis V001
hydrosphere NASA NSIDC_CPRD Level 4 netCDF-3
In plain English

What it measures. Daily estimates of the water and land conditions across High Mountain Asia, covering more than 30 measures including snow depth, snow water content, soil moisture, temperatures, evaporation, and streamflow.

How it's made. Generated by the Noah-MP land surface model, a physics-based simulation driven by precipitation and other inputs tailored to the region, spanning 2003 to 2020.

How & where you'd use it. Useful for understanding water supply, snowpack, and hydrology in a mountainous region whose rivers feed billions of people; this is modeled data rather than direct measurements.

Official description

This data set consists of a water budget reanalysis for the High Mountain Asia (HMA) region spanning the years 2003 through 2020. Estimates are provided for more than 30 parameters, including storages; fluxes; snow depth, extent, and snow water equivalent; temperature (land surface, soil, snow, and ice); surface albedo; soil moisture; evapotranspiration; and streamflow. The data were generated using the Noah Multi-Parameterization (Noah-MP) land surface model (Version 4.0.1), driven by precipitation estimates and hydrological inputs developed specifically for HMA.
