Discover and access climate data for California from the state's scientific and research community hosted on Cal-Adapt.
Climate datasets on Cal-Adapt include historical observations and downscaled climate projections. These climate datasets can be gridded or station based. A climate dataset consists of a collection of timeseries for one or more climate variables; additionally projections include timeseries for multiple future scenarios and global climate models (GCMs). All gridded climate datasets have a spatial extent that covers the state of California; some gridded datasets extend further into parts of Nevada, Oregon, Idaho and Mexico. Users can download climate datasets in multiple ways:
- Download original source files (NetCDF, CSV, etc.) provided by research institutions from Cal-Adapt Data server.
- Download spatial subsets from Cal-Adapt API at various temporal resolutions in raster or tabular formats for 4 priority models (HadGEM2-ES, CNRM-CM5, CanESM2, MIROC5) or 10 models selected by California’s Climate Action Team Research Working Group as having a good simulation of California's historical climate.
- Additionally users can download data from visualizations in all Cal-Adapt tools.
Cal-Adapt provides a public RESTful API for programmatically accessing climate data hosted on Cal-Adapt and makes it easier to build data driven applications and analyses.
