The Perils of Regridding: Examples Using a Global Precipitation Dataset

Original language description

Gridded precipitation datasets are used in many applications such as the analysis of climate variability or change and hydrological modeling. Regridding precipitation datasets is common for model coupling (coupling atmospheric and hydrological models) or comparing different models and datasets. However, regridding can considerably alter precipitation statistics. In this global analysis, the effects of regridding a precipitation dataset are emphasized using three regridding methods (first-order conservative, bilinear, and distance-weighted averaging). The differences between the original and regridded dataset are substantial and greatest at high quantiles. Differences of 46 and 0,13 mm are noted in high (0,95) and low (0,05) quantiles, respectively. The impacts of regridding vary spatially for land and oceanic regions, there are substantial differences at high quantiles in tropical land regions, and at low quantiles in polar regions. These impacts are approximately the same for different regridding me
