This repository contains the datasets and analysis scripts used in the manuscript "Evaluating Turbulent and Microphysical Schemes in ICON for Deep Convection over the Alps: A Case Study of Vertical Transport and Model–Observation Comparison”. The files include the processed ICON simulation, observational datasets and scripts used to generate the figures presented in this study. The description of each zipped data is mentioned below Topography.zip: Contains topography dataset and plotting code for Figure 1 Potential vorticity on the 350 K isentropic surface, 850 hPa pressure vertical velocity, and geopotential height from ERA5 hourly reanalysis for synoptic background conditions for Figure 2. Spatial_convection.zip: has Brightness temperature at 10.8 μm on 2021-07-08, 15:00 UTC from ICON simulations (with different turbulence and microphysics paramaterziation) and observations for Figure 3. Diurnal_convection.zip: Contains diurnal time-series data of brightness temperature at 10.8 μm for 8 July 2021 over the region 44.75°–47.75°N, 5.85°–10.5°E, derived from ICON simulations and observations for comparison. Spatial_overshooting_cross_tropopause.zip: Contains 10 CSV files organized into two datasets: (1) brightness temperature difference (BTD) fields and (2) spatial locations of cross-tropopause overshooting cloud tops. BTD (6.2 μm − 10.8 μm) is calculated as the brightness temperature difference between the water vapour (6.2 μm) and infrared (10.8 μm) channels at 15:00 UTC from ICON simulations and observations. The location files contain the coordinates of overshooting cloud tops identified using the common BT(6.2 μm − 10.8 μm) > 0 criterion, combined with the Cb-TRAM method for observations and the tropopause-crossing criterion for ICON simulations. Overshooting_fraction_area.zip: Contains 5 CSV files (4 for ICON simulations and 1 for satellite observations) with time-series data of the area fraction of overshooting cloud tops identified using the common BT(6.2 μm − 10.8 μm) > 0 criterion, combined with the Cb-TRAM method for satellite observations and the tropopause-crossing criterion for ICON simulations, obtained on 8 July 2021 over the study region. The archive also includes the code used to generate Figure 6. Diurnal_Ice_water_path.zip: Contains 5 csv files (4 for ICON simulations and 1 for satellite observations) with time series of mean ice water path over the region 44.75°–47.75°N, 5.85°–10.5°E. Also includes the code used to generate Figure 7. Cloud_Ice_water_vapor_above_tropopause_timeseries.zip: Contains 4 CSV files (corresponding to the 4 ICON simulations) with time-series data of mean cloud ice content (QI) above 1 km relative to the lapse-rate tropopause and water vapor content (QV, g m⁻²). The archive also includes the code used to generate Figure 8. Spatial_QI_above_tropopause.zip: Contains 4 NetCDF files (corresponding to the 4 ICON simulations) with the spatial distribution of QILRT at 15:00 UTC on 8 July 2021, representing cloud ice content above the lapse-rate tropopause. The archive also includes the code used to generate Figure 9. Timeseries_CAPE_vertical_wind_500hPa.zip: Contains 4 CSV files with time-series data from the 4 ICON simulations over the box region 44.75°–47.75°N, 5.85°–10.5°E for 8 July 2021, including the mean, 95th percentile, and maximum values of CAPE and 500 hPa vertical wind. The archive also includes the code used to generate Figure 10. VCS_turbulent_kinetic_energy.zip: Contains 4 NetCDF files with vertical cross-section data of turbulent kinetic energy (m² s⁻²) and potential temperature at 14:00 UTC. The archive also includes the code used to generate Figure 11. VCS_Cloud_Ice_Cloud_water.zip: Contains 4 NetCDF files with vertical cross-section data of vertical wind, cloud water content (QC), cloud ice content (QI) (g kg⁻¹), potential temperature (K), and lapse-rate tropopause altitude at 14:00 UTC. The archive also includes the code used to generate Figure 12. Hydrometeors_w.r.t_tropopause_before_during_convection.zip: Contains 4 NetCDF files with vertical profile data showing the mean differences between convective (14:00–16:00 UTC) and pre-convective (06:00–09:00 UTC) environments, relative to the lapse-rate tropopause, for total water (QT), ice water content (QI), water vapor (QV), and cloud water content (QC) over the selected region across the 4 ICON simulations. Positive values indicate enhanced mixing ratios during convective conditions. The archive also includes the code used to generate Figure A1. Hydrometeor_profiles.zip: Contains 4 NetCDF files with vertical profile data of total water (QT), ice water content (QI), water vapor (QV), and cloud water content (QC) relative to the lapse-rate tropopause over the selected region across the 4 ICON simulations. These profiles characterize the vertical distribution of hydrometeors and moisture during the study period. The archive also includes the code used to generate Figure A2.
