Temporal- and spatial-scale and positional effects on rain erosivity derived from point-scale and contiguous rain data

Franziska K. Fischer et al.
Data sets

Properties of erosive rains measured at 115 meteorological stations in Germany during 2001 to 2016 and the same properties as obtained from 1 km² rain radar pixels covering the location of the respective rain gauge Franziska K. Fischer, Tanja Winterrath, Karl Auerswald https://doi.org/10.13140/RG.2.2.26158.36168

Short summary
The potential of rain to cause soil erosion by runoff is called rain erosivity. Rain erosivity is highly variable in space and time even over distances of less than 1 km. Contiguously measured radar rain data depict for the first time this spatio-temporal variation, but scaling factors are required to account for differences in spatial and temporal resolution compared to rain gauge data. These scaling factors were obtained from more than 2 million erosive events.
