Changes in Observed Daily Precipitation over Global Land Areas since 1950

Abstract Estimates of observed long-term changes in daily precipitation globally have been limited due to availability high-quality observations. In this study, a new gridded dataset precipitation, called Rainfall on Gridded Network (REGEN) V1–2019, was used perform an assessment the climatic at each global land location (except Antarctica). This study investigates number wet days (?1 mm) and entire distribution wet- all-day records, addition trends annual seasonal totals from between 1950 2016. The main finding is that has intensified across majority areas throughout wet-day distribution. means when it rains, light, moderate, or heavy become more intense most globe. Widespread increases frequency are Asia United States, widespread intensity Europe Australia. Based comparison spatial pattern frequency, intensity, totals, we propose light moderate characterized by whereas extreme primarily changes. uncertainty estimates REGEN, highlights all results context grids with
