Abstract

Biases in satellite-based precipitation data are often region-specific and such information is important for quantifying input errors in hydrological models. Therefore, this study examines biases in daily precipitation data for a watershed in the southeastern United States. The AA. observed biases that occur seasonally and by magnitude. Seasonally, precipitation correlates well in most seasons but summer, likely due to the sporadic nature of convective precipitation that is a common precipitation mechanism in this region during the summer. Daily precipitation biases are around 5 mm, but the sign of the bias varies by season, with positive biases in all seasons but fall. Additionally, the AA. found that satellite-based data tend to overestimate light precipitation relative to the multi-gauge average, which more often records no precipitation
