The data linked here consist of downscaled projections of climate model output produced as part of CMIP3, CMIP5, and CMIP6, and gridded observed data that can be used in downscaling. These are not close to being exhaustive lists.

Global Data

Gridded observations

Climate projections - all statistically downscaled

  • NASA-NEX - daily data available through NASA’s Climate Data Services site. 0.25 degree spatial resolution precipitation, temperature and other variables.
  • CIL - daily data at 0.25 degree spatial resolution precipitation and temperature.
  • Worldclim - monthly data for precipitation, temperature, and derived bioclimatic variables at spatial scales from 1/6 degree to about 1 km.

U.S. (and North America) data

Gridded observations

  • Livneh - 1/16 degree daily gridded precipitation and temperature data, documented in Livneh et al., 2013.
  • adjusted Livneh - avoided splitting precipitation across days to represent extreme precipitation better, as described by Pierce et al., 2021
  • Daymet - includes precipitation and temperature at 1 km resolution.
  • PRISM - daily and monthly time series and climatological precipitation and temperature at spatial resolutions of 4 km to 800 m.

Climate Projections

  • USBR-GDO serves U.S. based precipitation and temperature data from multiple climate experiments (CMIP3, CMIP5, and eventually CMIP6) statistically downscaled to spatial resolutions from 1/8 to 1/16 degree. This archive is hosted by the Green Data Oasis.
  • LOCA2 - downscaled precipitation, temperature and other data at a 1/16 degree spatial resolution.

Runoff and streamflow projections

California data

Gridded observations and projections

  • CalAdapt - Serves CMIP5 projections of precipitation, temperature, runoff, and other variables, and is accumulating some CMIP6 projections. Has statistically and dynamically downscaled data.
