#### Description
The PRISM daily and monthly datasets are gridded weather
datasets for the conterminous United States, produced by the
PRISM Group at Oregon State University.
Grids are
developed using PRISM (Parameter-elevation Regressions on Independent
Slopes Model). PRISM interpolation routines simulate how weather
varies with elevation, and account for coastal effects,
temperature inversions, and terrain barriers that can cause rain
shadows. Station data are assimilated from many networks across
the country. For more information, see the [Descriptions of PRISM
Spatial Datasets](https://www.prism.oregonstate.edu/documents/PRISM_datasets.pdf).
