Assessing the Sampling Quality of a Low-Tech Low-Budget Volume-Based Rainfall Sampler for Stable Isotope Analysis
Fischer, Benjamin M C; Aemisegger, Franziska; Graf, Pascal; Sodemann, Harald; Seibert, Jan (Peer reviewed; Journal article, 2019-09-27)To better understand the small-scale variability of rainfall and its isotopic composition it is advantageous to utilize rain samplers which are at the same time low-cost, low-tech, robust, and precise with respect to the ... -
Meridional and vertical variations of the water vapour isotopic composition in the marine boundary layer over the Atlantic and Southern Ocean
Thurnherr, Iris; Kozachek, Anna V.; Graf, Pascal; Weng, Yongbiao; Bolshiyanov, Dimitri Yu.; Landwehr, Sebastian; Pfahl, Stephan; Schmale, Julia; Sodemann, Harald; Steen-Larsen, Hans Christian; Toffoli, Alessandro; Wernli, Heini; Aemisegger, Franziska (Journal article; Peer reviewed, 2020)Stable water isotopologues (SWIs) are useful tracers of moist diabatic processes in the atmospheric water cycle. They provide a framework to analyse moist processes on a range of timescales from large-scale moisture transport ... -
A new interpretative framework for below-cloud effects on stable water isotopes in vapour and rain
Graf, Pascal; Wernli, Heini; Pfahl, Stephan; Sodemann, Harald (Peer reviewed; Journal article, 2019-01-22)Raindrops interact with water vapour in ambient air while sedimenting from the cloud base to the ground. They constantly exchange water molecules with the environment and, in sub-saturated air, they evaporate partially or ...
