Hourly climate model runs for High Mountain Asia (4 km)

High Mountain Asia COAWST Hourly 4km Regional Climate Model Simulations V001
cryosphere NASA NSIDC_CPRD Level 3 netCDF-3
In plain English

What it measures. Hourly simulated weather and climate conditions across the High Mountain Asia region at about 4-km detail, with some values as hourly snapshots and others as hourly totals.

How it's made. Generated by a computer climate model (the COAWST system run as a regional climate model) over 15 years, rather than measured by an instrument.

How & where you'd use it. Used by NASA's High Mountain Asia team to study water resources in a region where direct measurements are scarce.

Official description

This data product contains either hourly accumulated or hourly snapshots of modeled data in the High Mountain Asia region, generated by the Coupled-Ocean-Atmosphere-Waves-Sediment Transport (COAWST) modeling system (operated as a regional climate model). These modeled data span 15 years and have been used by the NASA High Mountain Asia Team (HiMAT) to research water resource use.
