Rain A2 Change between 2000 and 2050 10th Percentile

% change in the long term mean annual total rainfall between 1986-2015 and 2036 - 2065. The mean annual rainfall for each downscaled global circulation model (GCM), i.e. csiro, gfdla20, gfdl21, miroc, mpi and ukmo using the the Cubic Conformal Atmospheric Model (CCAM) developed by CSIRO (Australia) and updated and modified by the CSIR (South Africa) was calculated for each of the 30 year periods. The percentage difference in the 30-year mean annual rainfall between the two periods was calculated for each of the six models as follows: ((rain2050 - rain2000)/rain2000)x100. The 10th percentile is based on these differences. Data are in raster format with a 0.5º resolution using a projected latitude / longitude coordinate reference system with `+proj=utm +zone=48 +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0`.
