CSPs: Kinetic energy of raindrops in the CSPs: characteristics of rain events
Abstract:
Rain was captured in open field and in vegetated conditions parallel to measurements in the Comparative study plots (CSPs). Throughfall as well as sandloss from splashcups can be used to derive kinetic energy from raindrops.
