and when available from other projects and are quality assured. AATSR global AOD products are under development
but first results show that the values are very high as compared to ground based measurements from AERONET which
are commonly used as ground truth. TOA radiance and AOD will be made available to Task 1 to evaluate the aerosol
radiative forcing calculated from RCMs and to refine the representation of aerosol optical properties within the climate
models.
Task 6.4: Climate change meteorology (lead: MetO, MPIC)
Meteorological data for driving the CTM simulations in WP5 will be provided from the GCMs and RCMs used in this
WP6, running for present-day conditions as well as one of the standard future scenarios (which will be chosen to be
consistent with those planned for the IPCC 5 th Assessment Report). This will be most important for the regional
modelling where changes in the local climate might significantly affect the chemistry and transport of pollutants.
