open position at German Aerospace Center, Institute of Atmospheric Physics
by Simon.Unterstrasser＠dlr.de 25 Jul '23

25 Jul '23

Dear colleagues, There is an open PostDoc position at DLR (German Aerospace Center) Oberpfaffenhofen, Institute of Atmospheric Physics in the group for high-resolution contrail modelling. The project duration is three years. We have been employing a particle-based ice microphysics code for many contrail-related modelling studies over the last >10 years. See e.g. http://www.pa.op.dlr.de/~/SimonUnterstrasser/publikationen.html The present research topic is on understanding contrails from airplanes with hydrogen combustion, where the initial formation process differs from that of conventional contrails from kerosene combustion. The work is part of a larger collaborative effort using contrail in-situ measurements, LES models and GCM. Eventually, we come up with an estimate of the contrail mitigation potential of a decarbonized aviation using hydrogen as energy carrier. Clearly, this work is of interdisciplinary nature and a background on aerosols, cloud microphysics and/or CFD is welcome. More information can be found here: https://www.dlr.de/dlr/jobs/desktopdefault.aspx/tabid-10596/1003_read-51393/ Even though the job description is in German, the position is clearly open to persons with no German language skills. Feel free to forward this mail to interested PostDocs. If you have questions on the position, do not hesitate to contact me. Thank you and best wishes, Simon -------------------------------------------------------------- Dr. Simon Unterstraßer Deutsches Zentrum fuer Luft- und Raumfahrt e.V. in der Helmholtz-Gemeinschaft Institut fuer Physik der Atmosphaere Muenchner Strasse 20 D-82234 Wessling Telephone +49 8153 28 2553 Telefax +49 8153 28 1841 E-mail simon.unterstrasser(a)dlr.de<mailto:simon.unterstrasser@dlr.de> Internet http://www.pa.op.dlr.de/~SimonUnterstrasser/

AGU Fall Meeting: Session of Interest
by Fabian Hoffmann 24 Jul '23

A109 - Processes of (Sub) Cloud Scales: Modeling, Observations and Parameterizations https://agu.confex.com/agu/fm23/prelim.cgi/Session/188746 Session Description: Clouds continue to challenge our understanding and are major sources of uncertainty in numerical weather prediction and climate projection. Key to addressing such outstanding challenges associated with clouds are to understand the processes that occur at space-time scales of individual clouds or smaller, including entrainment/detrainment, turbulent mixing, turbulence, cloud microphysics, radiation, aerosol activation/deactivation, and boundary layer processes. The temporal and spatial scales of these processes are essentially smaller compared to the time and grid scales in numerical models. These sub-grid cloud processes pose particular challenges to numerical simulations, observations, as well as parameterization development. Representations of these sub-grid cloud processes will likely become more important as weather and climate models increase their resolutions. This session focuses on process-level modeling, observations (both laboratory and field), and parameterizations of such (sub) cloud processes. Also invited are studies on unified treatment of different processes, process coupling, and integration from observations, theories to models. Sincerely, Chunsong Lu (Nanjing University of Information Science and Technology) Yangang Liu (Brookhaven National Laboratory) Lulin Xue (National Center for Atmospheric Research) Alexei Korolev (Environment Canada Toronto)
