CRU temperature time series at the four locations in the African highlands. The bold line shows the trend obtained for each of these data with SSA. Because the latitude of Muhanga is almost on the boundary between two grid points in the CRU global grid, both the grid points above and those below the latitude of 3.00 S were considered. All results remain the same for these two time series, and we report here only the results for the grid point centered at 2.75 S (a, Kericho; b, Kabale; c, Gikongoro; d, Muhanga).
