Average monthly precipitation during the wet season is 260 mm (10 inches). (globalsurfers.com)
It was valuable because it was produced from easily available data, total monthly precipitation (P) and evaporation (E) to produce a P / E Index. (drtimball.com)
We illustrate the inconsistent relationship between RMSE and MAE by appraising errors associated with the spatial interpolation of monthly precipitation totals, evaluated over 5 years, at locations across South America (Figure 1). (eos.org)
