- The project strategy is based on an integrated approach combining an intensive experimental field campaign and spaceborne observations, radiative transfer, and climate modelling with Regional Climate Models (RCM, lien models) better adapted than global circulation models to capture the high complexity of the Mediterranean region.
- In particular, we propose a summer field experiment in summer 2013 based on in situ and remote sensing observations from surface super-sites and airborne platforms including the French ATR42 and F-20 research aircrafts.
- The ADRIMED project is divided in 4 tasks (including the coordination task, T0) of which the three main tasks are summarized in the following figure.

- Task 1 is related to the development of an intensive experimental campaign, based on surface and airborne observations over the Occidental Mediterranean region during summer 2013 (June – July) for creating an updated databases of the physical, chemical, optical (with a focus on absorption properties) properties as well as the vertical distribution of the major “Mediterranean aerosols”.
- Task 2 is dedicated to the utilization of these experimental observations for (1) estimating the 1D local direct radiative forcing of aerosols over the instrumented super sites at the sea-surface, Top of the Atmosphere (TOA) and within the atmospheric layer (ATM) and (2) improving significantly the aerosol parameterizations used in the Regional Climate Models. Such improved version will be used to estimate the aerosol optical properties at the regional scale, which is considered as prerequisite for further investigations on possible feebbacks on the water cycle.
- Task 3 is dealing with feedbacks of the direct radiative effect of aerosols on the Med. water cycle. In a first step, climate simulations will be conducted for past & present time (1990 – 2010). In a second phase, the same kind of simulations will be carried out but using future climate boundary forcing provided by IPCC climate change and emission scenarios.
