SUMMARY:Dynamic Adaptive Meshes in ESM Applications: From Shallow-Water to
  Chemistry-Climate Models
DESCRIPTION:Kerstin Hartung (DLR), Daniel Caviedes Voullieme (Forschungsze
 ntrum Jülich), and Patrick Jöckel (Deutsches Zentrum für Luft- und Raumfah
 rt e.V. (DLR))\n\nIn this contribution to the mini symposium on“Dynamic ad
 aptive scalable methods in Earth system modeling” we discuss the challenge
 s and potential benefits of adaptive meshes in Earth system models conside
 ring two applications. Firstly, MESSy, the Modular Earth Submodel System, 
 is a software framework used for global and regional chemistry-climate mod
 eling. For this application AMR methods are of potential interest since se
 veral 100 to 1000 of chemical tracers increase the memory and runtime requ
 irements compared to general circulation models by at least a factor 10. A
 s a step towards a full AMR chemistry-climate model simulation, MESSy was 
 connected to the AMR library t8code and the flow solver Trixi.jl. An evalu
 ation of the integration will be shown based on an idealized flow test cas
 e. Second, SERGHEI (Simulation EnviRonment for Geomorphology, Hydrodynamic
 s, and Ecohydrology in Integrated form) is a multi-dimensional, multi-doma
 in, and multi-physics model framework. Its shallow-water component is used
  for hydrological and environmental hydrodynamic simulations and is curren
 tly exploring AMR. We describe the implementation and the implications it 
 has in the design of SERGHEI, as well as preliminary results of AMR applie
 d to shallow water problems.\n\nDomain: Climate, Weather, and Earth Scienc
