The updated model code can be found at zenodo.org (DOI:10.5281/zenodo.7944174). The data can be used to replicate the results shown in the manuscript. Contained are results produced by the updated CAABA/MECCA (version 4.5.6-rc.1) and reference data from CAABA/MECCA version 4.5.5. In version 4.5.6-rc.1, new biogenic and anthropogenic species are introduced to the model (limonene and long-chained alkanes) with refined multiphase chemistry, while new reaction pathways are added for existing compounds (isoprene, benzene and IEPOX). The output is generated to evaluate model results in terms of temperature- and NOx-dependency.The data include the reference runs at 278K and 298K ("OLD_278.nc" and "OLD_298.nc" ), the base runs with the updated model ("BASE_278.nc" and "BASE_298.nc") and model runs at varying NOx concentrations ("LNOX.nc", "MNOX.nc" and "HNOX.nc").CC0 WaiverBASE_278.ncCAABA/MECCA version 4.5.6-rc.1 output at 278 Kapplication/x-netcdfBASE_298.ncCAABA/MECCA version 4.5.6-rc.1 output at 298 Kapplication/x-netcdfHNOX.ncCAABA/MECCA version 4.5.6-rc.1 output at 298 K and high NOxapplication/x-netcdfLNOX.ncCAABA/MECCA version 4.5.6-rc.1 output at 298 K and low NOxapplication/x-netcdfMNOX.ncCAABA/MECCA version 4.5.6-rc.1 output at 298 K and medium NOxapplication/x-netcdfOLD_278.ncCAABA/MECCA version 4.5.5 output at 278 Kapplication/x-netcdfOLD_298.ncCAABA/MECCA version 4.5.5 output at 298 Kapplication/x-netcdf
