Kidson Medal Award

The 2018 Edward Kidson Medal has been awarded to Dr Kevin Trenberth for his paper “How often does it really rain?” (DOI:10.1175/BAMS-D-17-0107.1). The paper uses a new near-global satellite and observed surface precipitation data set at high spatial (0.25 degrees) and temporal (hourly) resolution to address the question of over what fraction of time or over what fraction of space is it actually raining at the same time. It draws many useful inferences about the frequency of precipitation, including the impacts of global warming on precipitation frequency and intensity.
