GRIDMET: University of Idaho Gridded Surface Meteorological Dataset (IDAHO_EPSCOR/GRIDMET)

The Gridded Surface Meteorological dataset provides
high spatial resolution (~4-km) daily surface fields of temperature,
precipitation, winds, humidity and radiation across the contiguous
United States from 1979. The dataset blends the high resolution
spatial data from PRISM with the high temporal resolution data
from the National Land Data Assimilation System (NLDAS) to produce
spatially and temporally continuous fields that lend themselves
to additional land surface modeling.

This dataset contains provisional products that are replaced with
updated versions when the complete source data become available.
Products can be distinguished by the value of the ‘status’ property.
At first, assets are ingested with status=‘early’. After several
days, they are replaced by assets with status=‘provisional’.
After about 2 months, they are replaced by the final assets with
status=‘permanent’.
