Characterization of Brown Carbon absorption in different European environments through source contribution analysis

This dataset provides modeled OA mass concentrations and absorption coefficients across 12 European stations, generated using the Multiscale Online Nonhydrostatic Atmosphere Chemistry (MONARCH) model.

The data is provided in NetCDF format and includes the following:

1. Mass Concentrations: For each station, the dataset includes OA mass concentrations categorized by emission sources:

   • Residential (poaresi)

   • Traffic (poatraf)

   • Shipping (poaship)

   • Fires (poagfas)

   • Other sources (poaothr)

   • Secondary organic aerosols (SOA)

2. Absorption Coefficients: The absorption coefficient of BrC at 370 nm (AbsBrC370) is calculated for each station. The dataset includes two approaches:

   • Aggregated data across all stations

   • Data separated by individual stations
     Additionally, results are provided for specific cases (Case 4 and Case 5).
