microHH large-eddy simulation data of reactive CO2 and NO2 plumes from an idealized industrial point source for four emission strengths

This dataset contains output from large-eddy simulations (LES) of reactive trace gas plumes from an idealized industrial point source, performed with the microHH model (branch main_kpp, commit 70ec6af5). Four scenarios with different CO2 emission strengths are provided: 2, 2.5, 5, and 12.5 Mt/yr. For each scenario, the dataset includes 3D concentration fields for CO2, NO, NO2, and O3, 3D wind velocity fields (u, v, w), vertical profile statistics, and the model configuration file. The simulations use a domain of 16384 × 8192 × 4096 m at 64 m uniform resolution with KPP photochemistry (15 species), a 5 m/s westerly background wind, and a ~440 m deep convective boundary layer representative of Riyadh, Saudi Arabia in winter. The data support the assessment of synergistic CO2 and NO2 satellite observations for industrial emission quantification in the context of the TANGO mission. The dataset is described in: Borsdorff et al. (2026), TANGO CO2 and NO2 Observations: Synergistic Usage to Improve Emission Quantification and Characterize Atmospheric Chemistry, Atmos. Meas. Tech.
