Data Catalog

We refer to the datasets in the Cal-Adapt API as resources. Each resource is represented by a unique endpoint (URL). The following is a list of climate datasets in the Cal-Adapt API. We are actively adding new resources to the API so this list may not reflect the most up to date information.

Climate Variables

  • LOCA downscaled climate projections from Scripps Institution of Oceanography, UC San Diego (Pierce et al, 2014).
    • Maximum Temperature tasmax, Minimum Temperature tasmin, Precipitation precip
    • Daily and annual averages
    • 10 GCMs, 3 scenarios, Envelope
  • Climate variables produced by the Variable Infiltration Capacity (VIC) model using downscaled LOCA data.
    • Snow Water Equivalence swe
    • Monthly averages
    • 10 GCMs, 3 scenarios
  • Gridded historical observed climate data from UW Hydro | Computational Hydrology (Livneh et al, 2015)
    • Maximum Temperature tasmax, Minimum Temperature tasmin, Precipitation precip

Global Climate Models (GCM)

The following GCMs have been selected by California state agencies as priority models for Fourth Assessment Research. Data for these models is available through the cal-Adapt API. Downscaled data for 22 other GCMs is available as NetCDF files from the Cal-Adapt Data Server.

Different temporal aggregations are available for climate variables through the API. See Raster Series to find out what’s available in the API.

  • year - Annual averages
  • month - Monthly averages
  • day - Daily values

Vector Data

In addition to climate data, the Cal-Adapt API also has endpoints for vector datasets representing administrative boundaries, hydrological boundaries and the LOCA model grid.
