This report presents the high-resolution nature runs covering a domain centred around the town of Berlin. These nature runs are nested in the European runs (described in the first part of Deliverable D2.4), themselves nested in the global Tier-1 runs (Deliverable D2.2). These simulations are produced using two separate models, COSMO-GHG and LOTOS-EUROS. COSMO-GHG computes the meteorology and tagged tracers for multiple anthropogenic and biogenic sources. The meteorological outputs drive the offline model LOTOS-EUROS, which computes reactive trace gases and aerosols on top of the tagged tracers.
