Uganda PRECIS (RCM) Experiments

PRECIS (RCM) experiments for Uganda and surrounding region



High-resolution (daily timestep, 0.22° grid) climate data are available* for Uganda and the surrounding region from Regional Climate Model (RCM) experiments conducted in UCL Geography by Lucinda Mileham using PRECIS (Providing REgional Climates for Impacts Studies) developed at the Hadley Centre of the UK Met Office. Please consult the PRECIS website for further details of this regional climate model.



RCM experiments using PRECIS were conducted cover the region defined by latitudes 7.3°S to 8.0°N and longitudes 26.0°E to 39.0°E. This region includes a 250 km buffer zone for the modelled domain. Please note that data from the buffer zone should not be used as errors can arise close to boundary between lower-resolution GCM boundary data and higher-resolution RCM data.

Data download

To download climate data, please clicking on the following link - Uganda PRECIS (RCM) experiments - to access the data directories. Filenames in the data directory reflect both the climate variable and model run (see below) used to generate that variable. Datafiles are available in netcdf format and can be read by all common climate data analysis tools such as GRADS, CDO, NCL, R, MatLab and IDL.
