Weather-driven evolution of atmospheric emissions, concentrations and deposition over Europe from 1990 to 2022

These data provide the weather-driven evolution of atmospheric emissions, atmospheric concentrations and deposition across Europe over 1990–2022 using an enhanced version of the CHIMERE chemical transport model. The model includes meteorology-dependent anthropogenic emissions, varying 8-day leaf area index from satellite data over the whole period, and updated parameterizations for deposition as well as soil and biogenic emissions. The data were generated by assuming constant anthropogenic practices (2018 selected as a reference year) over the whole and therefore isolate the effect of meteorology on results. Evolution of emissions due to change of practices or to reduction of emission factors are therefore not taken into account.

These data were used to study the weather-driven trends during the period. The results and the methodology are presented in "Couvidat et al. (2026, submitted to ACP): Determination of weather-driven trends of atmospheric emissions, concentrations and deposition over Europe during the last decades"

Data are splitted into 3 tar archives:

• emissions.tar: NetCDF of annual biogenic emissions (isoprene, monoterpene, sesquiterpene and the sum of all VOC), soil NO emissions and fungal spore emissions
• surface_concentrations.tar: NetCDF files of SOMO35, AOT40 and annual surface concentrations of O3, NO2, PM10, PM2.5, Fungal spore, Sea salts, Secondary Inorganic Aerosols (SIA), Secondary Organic Aerosols(SOA), Anthropogenic Primary Particles (TPM)
• deposition.tar: NetCDF files of annual deposition (dry, wet and total) of reduced nitrogen (NHx), oxidized nitrogen (NOx) and oxidized sulfure (SOx)
