Multimodel GCM-RCM Ensemble-Based Projections of Temperature and Precipitation over West Africa for the Early 21st Century

Table 2

Mean bias and spatial root mean square difference (RMSD) at different subdomains considered in Figure 1(b) for CMAP, CRU, and GPCC rainfall with respect to GPCP. Observational datasets (CMAP, CRU, and GPCC) are interpolated to GPCP grid. Bias is expressed as percentage of GPCP value while RMSD as mm/day.
