Which measurement instruments can be usefully combined to observe a height profile of the entire troposphere, especially during cloud cover and precipitation? How could we use such measurements to parameterize precipitation evaporation, for example? ===== Projects ===== ==== Current ==== **Process-level Understanding of Sublimation and Evaporation of Precipitation** as part of the (AC)3 project.\\ Duration: 06/2024 - 12/2027\\ Funded by: DFG Deutsche Forschungsgemeinschaft\\ [[https://ac3-tr.de/pages/e05.html|Show details]] ==== Completed ==== **A novel synergistic retrieval approach to enable tropospheric temperature and humidity profiling under all weather conditions for an improved quantification of evaporation rates**\\ Duration: 04/2020 - 03/2023\\ Funded by: DFG Deutsche Forschungsgemeinschaft\\ [[https://fob.uni-leipzig.de/public/details/forschungsprojekt/5981?lang=en&fis_persid=af81co51|Show details]] ===== CV ===== ==== Professional career ==== * since 04/2020: Scientific employee at Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany\\ * 01/2020 - 03/2020: Scientific employee at the Leibniz Institute for Tropospheric Research (TROPOS)\\ * 01/2017 - 12/2019: Scientific employee at Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany\\ * 01/2013 - 01/2017: PhD student at Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany\\ ==== Education ==== * 01/2013 - 01/2017: PhD in meteorology, Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany, thesis: “Optimal estimation of water vapour profiles usinga combination of Raman lidar and microwave radiometer”.\\ * 10/2010 - 12/2012: Master of science in meteorology,Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany, Master thesis: “Bestimmung der vertikalen Aerosolverteilung über PuntaArenas, Chile (53.2°S, 70.9°W)”.\\ * 10/2006 - 09/2010: Bachelor of science in meteorology,Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany, Bachelor thesis: “Stadtklima und Luftschadstoffe in Leipzig”.\\ ===== Research Interests ===== * Remote sensing * Raman lidar * Mikrowave radiometer * Cloud, rain, and wind profiling radar * Spaceborn lidar observations with CALIOP on board of CALIPSO * Inverse modelling * Atmospheric retrieval algorithm development * Synergy of measurement systems * Sublimation and evaporation of precipitation with special focus on Arctic clouds * Derivation of aerosol optical properties based on Raman lidar technique ===== Publications ===== **2025** Roschke, J., Witthuhn, J., Klingebiel, M., Haarig, M., **Foth, A.**, Kötsche, A., and Kalesse-Los, H.: Discriminating between “drizzle or rain” and sea salt aerosols in cloudnet for measurements over the Barbados cloud observatory, Atmos.
