title: Enviro-HIRLAM model output for November 2023 - Black Sea / Ukraine case study (reference simulations)

description: Case study: two cyclones over the Black Sea and the southern part of Ukraine (18-20.11.2023 first cyclone, 26-27.11.2023 – second deep cyclone).

 

Model configurations: reference (REF) run without aerosol effects for three horizontal resolutions (nested domains) – 15 km, 5 km, and 2 km.

Other model output with different configurations: indirect aerosol effects included (IDAE) & no anthropogenic emissions and with indirect aerosol effects included (IDAE_NA) are shared as separate datasets via the following links: https://doi.org/10.5281/zenodo.15593004 and https://doi.org/10.5281/zenodo.15593157

The presented dataset contains the seamless Environment – HIgh-Resolution Limited Area Model (Enviro-HIRLAM) model output for 9 simulations with different configurations. The model description can be found by the following link: https://doi.org/10.5194/gmd-10-2971-2017.

 

Model output and variables description is presented in the file: Enviro-HIRLAM_Forecast_Outputlist74.pdf (archived with data).

The description of the vertical grid (40 levels) is presented in the file: Enviro-HIRLAM_VerticalGrid_FourtyLevel.pdf (archived with data).

 

Periods of data available for download: 17-21.11.2023 and 25-28.11.2023.
