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 cumulative_SALSA.py
