Rain 1986-2015 Median

The modelled current long term annual climate conditions for the 30-year period 1986-2015. The total daily rainfall values simulated by six different global circulation models (GCMs), i.e. csiro, gfdl20, gfdl21, miroc, mpi, and ukmo were downscaled with the Cubic Conformal Atmospheric Model (CCAM) developed by CSIRO (Australia) and updated and modified by the CSIR (South Africa). The daily rainfall values were summed to yearly totals and the mean annual total rainfall were calculated for each downscaled global circulation model for the 30 year period. The median values are the 50th percentile values of the mean annual rainfall values for the six downscaled GCMs. 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`.
