In hllauca/RClimChange: A package to manipulate Global Climate Models from NCCS THREDDS NEX-GDDP-CMIP6

'RClimChange' package

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.

NEX-GDDP-CMIP6: https://ds.nccs.nasa.gov/thredds/catalog/AMES/NEX/GDDP-CMIP6/catalog.html
