Issue with the _a2 emission in the RCP85 simulations
The _a2 emissions were incorrectly set in the RCP85 simulations. This leads to the _a2 number not matching with the mass for the emissions. As result, more mass gets added but the number of aerosols stays the same meaning particles would initially get larger. However, this has a minimal impact on the total aerosol burden because of a much smaller total mass in _a2 for sulfate than in _a1 (accumulation mode) and therefore has a very small impact.
The influence of this error was tested in an additional RCP85 scenario simulation in which the _a2 emissions were correctly set and the influence of the incorrect _a2 emissions on climate properties was found to be minimal.
