Monitoring and Forecasting of Global Atmospheric Composition

MACC monitors the composition of the atmosphere in near-real-time by assimilating observations of various meteorlogical variables as well as reactive gases and aerosols into its data assimilation system. The observations are thus used to constrain a computer model that describs the state of the atmosphere at any one moment.

Verification

The quality of the global near-real-time monitoring and forecasting services is routinely monitored. Various independent observations are used to detect problems early on and also to provide a first indication of the accuracy of the products to the users. The MACC global verification page provides access to the various verification and monitoring plots.
