Global Climate Data distributes tools written in MATLAB for creating 30-arcseconds (approximately 1 km) grids of hindcast (20th century) and projected (21st century) monthly precipitation and air temperature data for any global land area. The process utilizes globally available gridded data, which enables the tools to be applied with equal ease for any global land area. All of the tools are open source and available on this site free of charge.
Recent updates to the website include the downscaling package and an associated user manual. Please do not hesitate to contact Thomas Mosier (firstname.lastname@example.org) with questions on how to use these tools, comments on this work, or suggestions.
