MACC provides support to climate change studies by monitoring atmospheric concentrations of carbon dioxide and methane and their fluxes as well as aerosols.

	Monitoring of Greenhouse Gases and Fluxes Analyses of atmospheric CO2 and CH4 and their surface fluxes running 6 months behind real time.
	Reanalysis of Greenhouse Gases and Fluxes Renalysis of atmospheric CO2 and CH4 and their surface fluxes for the period 2003 - 2010.
	Monitoring of Global Aerosols Daily analyses and 4-day forecasts of global  aerosol.
	Reanalysis of Global Atmospheric Composition Reanalysis of atmospheric composition for the period 2003 - 2010
	Observed Aerosol Optical Depth and Aerosol Speciation Record Aerosol parameters are retrieved from a combination of simultaneous AATSR and SCIAMACHY measurements.
