2016-09-12: LOCA data are now available for download from the following sites:
- Lawrence Livermore National Laboratory Green Data Oasis This has the original set of files in netcdf format
- NASA OpenNEX The LOCA downscaling was done on NASA supercomputers, and the data is available from the NASA Earth Exchange
- US Geological Survey Geo Data Portal provides THREDDS access to the data
- Cal-Adapt provides access to the data over California, and provides value-added abilities to visualize and analyze the data
- Desert Research Institute (DRI) SCENIC (Southwest Climate and Environmental Information Collaborative)
Please read this special note about the LOCA data calendar; LOCA has been interpolated to a standard calendar from the various original global model calendars.
The LOCA elevation field is now available.

LOCA is a statistical downscaling technique that uses past history to add improved fine-scale detail to global climate models.
We have used LOCA to downscale 32 global climate models from the CMIP5 archive at a 1/16th degree spatial resolution, covering North America from central Mexico through Southern Canada. The historical period is 1950-2005, and there are two future scenarios available: RCP 4.5 and RCP 8.5 over the period 2006-2100 (although some models stop in 2099).
The variables currently available are daily minimum and maximum temperature, and daily precipitation. Over the next year we will begin running the VIC hydrological model with the downscaled data, which will give many more variables, such as snow cover, soil moisture, runoff, and humidity, all at a 1/16th degree spatial resolution on a daily timescale.

When LOCA data is publicly released, you will also be able to access it from here.
