This is an experimental package with a function for downloading and subsetting daily Global Climate Models (GCM) from NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6). Readers can find more data set details in: https://www.nccs.nasa.gov/services/data-collections/land-based-products/nex-gddp-cmip6
Future implementations will consider additional functions to post-process and bias-correct this data set.
