Monitoring of Atmospheric Composition and Climate

The EU project MACC develops novel integrated data analysis and modelling systems for the chemical composition of the atmosphere. The MACC data services precede the GMES Atmospheric Service which is planned to become operational by 2014.

The MACC system assimilates observational data from major air pollutants, greenhouse gases, and aerosols into numerical models and generates global and regional forecasts and analyses. Regional modeling is focused on Europe. MACC is coordinated by the European Centre for Medium-range Weather Forecasts (ECMWF) in Reading, United Kingdom.

Daily analyses and forecasts of the chemical composition on the global and on the European scale are produced, but also products from the so-called reanalysis, which retrospectively analyses a longer time period (2003-2012) with a consistent model system. All MACC products can be accessed via the project homepage

IEK-8 is a central MACC partner: The working group Global Modelling coordinates the sub-project on reactive gases and provides the global chemistry transport model MOZART. Coupled to the data assimilation and forecast system at ECMWF, MOZART is applied for global operational forecasts and reanalyses of the reactive trace gases. Cooperating directly with the users, we provide the daily MACC products for reactive gases, aerosols and wildfire emissions via our „Web Coverage Server“ JOIN to be used as boundary conditions for regional modellers world-wide. Moreover, the group contributes with it’s expertise in atmospheric chemistry and emissions, particularly trace gases and aerosols from forest and savannah fires.

The working group Regional and Inverse Modelling leads the sub-project on regional data assimilation and provides in cooperation with Rhenish Institute for Environmental Research in Cologne (RIU) daily forecasts of European air quality with the regional chemistry transport model EURAD-IM.
