Good quality data on precipitation are a prerequisite for applications like short-term weather forecasts, medium-term humanitarian assistance and long-term climate modelling. In Sub-Saharan Africa however, terrestrial climate station networks are frequently insufficient as in the Cuvelai-Basin in Namibia and Angola. As part of SASSCAL task 16, this study analyses six rainfall products with respect to their performance in a crop model (APSIM) to obtain nutritional scores of a household's requirements for dietary energy and further macronutrients.
