UKCA-MODE aerosol (StdTrop+aerchem): Evaluation against observations

This page gives an overview of model evaluation conducted with the UKCA StdTrop + Aerchem chemistry coupled to the GLOMAP-mode aerosol scheme at v7.3 (N96L38).

In each case, the UKCA simulated aerosol property is compared to that from an equivalent run with the CLASSIC aerosol scheme which is used in HadGEM2-ES.
