Fig. 9 — Results of cross-validation for mean temperature (TMP). (a) Shows the location and correlation coefficient (r) of each station estimated from nearby interpolants; (b) as for (a), but showing the mean absolute error (MAE); (c,d) show the distributions of r and MAE respectively. In order to improve the mapping of colours, the largest MAE value, 4.27 °C, has been replaced with a black cross (at Pangnirtung, on Baffin Island, 66.15°N, 65.72°W).
