(a) Mean absolute errors (L1-norm) of 16 test cases (black crosses) calculated using different resolution in time and space. The data point at 50 m DTM resolution and 3 h integration time-step serves as a benchmark; cf. lower left cross. The black dashed line shows the location of the profile displayed in (b) and the black circle indicates our chosen DTM resolution of 180 m pixel−1. The mean absolute errors are color-coded. (b) Profile showing the mean absolute error with increasing resolutions at a fixed time-step of 12 h. Our adopted DTM resolution is indicated as a black circle.
