-------- Forwarded Message -------- Subject: Invitation to Model Intercomparison Case Study on Mixed-Phase Cloud Chamber -- International Cloud Modeling Workshop (ICMW) 2024 in South Korea Date: Mon, 30 Oct 2023 15:00:00 -0600 From: Sisi Chen <sisichen(a)ucar.edu> CC: Wang, Aaron <aaron.wang(a)pnnl.gov>, Steve Krueger <Steve.Krueger(a)utah.edu> Dear colleagues and friends, We cordially invite you to participate in a model intercomparison case study that will be featured in the upcoming International Cloud Modeling Workshop (ICMW) 2024 in July. This specific case study focuses on the cloud chamber simulation of mixed-phase clouds, and aims to foster a detailed understanding of mixed-phase processes within a controlled environment. Workshop Schedule and Venue: Date:8 to 12 July 2024 Location:Yonsei University, South Korea. This workshop precedes the International Conference on Clouds and Precipitation (ICCP) in Jeju, South Korea. More information is available at https://iccp2024.kr/ <https://iccp2024.kr/> Case Description & Science Objectives: This case is focusing on the model intercomparison of mixed-phase processes in the Pi cloud chamber. The detailed case description with model configuration can be found in this Google Document: PI chamber mixed-phase case description <https://docs.google.com/document/d/1Q_I0hx31kulrDaIFoezJGIQTEVyBYBtNVQuhSom…>(let us know if you could not access the file). The objectives of this case study are to answer: * How well do models represent mixed-phase processes, in particular those processes that determine the interactions of (supercooled) liquid and ice? * How supercooled liquid responds to various ice nucleus injection rates? * What is the critical point (microphysical conditions) when cloud glaciation happens? We anticipate that the collective insights gained from this intercomparison effort will significantly contribute to the fundamental and process-level understanding of mixed-phase cloud processes. Participation: Individuals/groups who are interested in cloud modeling using DNS, LES, parcel models, theoretical models, ML emulators, and other numerical tools are all welcome to participate in the model comparison project. Feel free to forward it to others who are interested in participating. If you are interested in participating in the model intercomparison, please reply to Sisi Chen (sisichen(a)ucar.edu <mailto:sisichen@ucar.edu>) by December 20, 2023, with your Name, Institution, and Email.You will then be added to the group mailing list for further information and updates. Overall Timeline: Oct 2023 Announcements & invitations Dec 20, 2023 Confirmation of participation May 1, 2024 Results received from the participants May-July 2024 Data post-processing & communication with participants July 8-12 2024 International Cloud Modeling Workshop in Seoul Post workshop Paper summarizing the case We’d also like to bring to your attention that there will be aCloud Chamber Workshop and Cloud Probe Workshopon the weekend following the ICMW and preceding the ICCP, from 13 to 14 July 2024 at the National Institute for Meteorological Studies (NIMS).

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

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)
