Global model data for "Revealing uncertainties in defining the sensitivity of cloud formation to aerosol changes" by Virtanen A., et al. (2024)

The data includes simulated global model data sampled at the measurement stations. ECHAM-HAM, ECHAM-SALSA, and UKESM data is in CSV text format, NorESM data is in NetCDF format. Python scripts cumulative_M7.py and cumulative_SALSA.py calculate cumulative historgrams for activation dry diameters for ECHAM-HAM and ECHAM-M7.

Usage of Python scripts: cumulative_M7.py <station_name> cumulative_SALSA.py <station_name>
