Ekman Bolin Centre Database 2023 Datafile Atmosphere Aerosols Aerosol-cloud interaction Large-eddy simulations Susceptibility regimes Stratocumulus-topped marine boundary layer Earth science > Atmosphere > Aerosols > Cloud condensation nuclei Annica Ekman 2023-05-12T13:31:51+00:00 English 1 The data are provided in a large (7.6 GiB) zip file. The directories of the directory tree is used to indicate the model setup. The file tree containing all sets of sensitifity simulations looks like the list below. ##### Directory structure - `FDT` simulations with fixed timestep - `dt_1e-1_r0_1e-6` dt = 0.1 s, r0 = 1 micrometer - `dt_1e-1_r0_rwet` dt = 0.1s, r0 from wet aerosol PSD - `dt_1e-1_r0_rwet_noREN` dt = 0.1s, r0 from wet aerosol PSD, no renormalization - `LRD` large domain simulations - `r0_01e-06` - `r0_05e-06` - `r0_10e-06` - `SMD` small domain simulations - `r0_010e-7` - `r0_020e-7` - `r0_030e-7` - `r0_040e-7` - `r0_050e-7` - `r0_060e-7` - `r0_070e-7` - `r0_080e-7` - `r0_090e-7` - `r0_100e-7` - `rwet` In each of the above direcories, a set of simulations are stored where the directory name indicated the prescribed aerosol number concentration (in #/kg) e.g.,: - `10e07` - `10e08` - `10e09` - `10e10` - `50e07` - `65e06` The output data contains (a) 3D output (for the last simulated hour 18000 s to 21600 s), (b) profiles, and (c) time series for relevant atmospheric variables (e.g., cloud droplet number density, aerosol number density, updraft velocity, relative humidity, etc.). - `DYCOMS_MPI.nc` 3D output (for the last simulated hour 18000 s to 21600 s; NetCDF file) - `T_S` time series (text file) - `profiles_tot.nc` profiles (NetCDF file) The output data contains * 3D output (for the last simulated hour 18000 s to 21600 s; NetCDF File with filename `DYCOMS_MPI.nc`), * profiles (NetCDF File with filename `profiles_tot.nc`), and * time series (Text file with filename `T_S`), for relevant atmospheric variables (e.g., cloud droplet number density, aerosol number density, updraft velocity, relative humidity, etc.). With this dataset and the code from the GITHUB repository [matschwa/2023-LES-susceptibility](https://github.com/matschwa/2023-LES-susceptibility) all plots and analysis from the paper by Schwarz et al. (2023) can be reproduced. The MIMICA model is described by Savre et al. (2014). The DYCOMS-II field study is described by Stevens et al. (2003). The transition from the aerosol- to the updraft-limited susceptibility regime was first described by Reutter et al. (2009).
