Atmospheric chemistry fully integrated

On 18 September MACC-III implemented the new Composition-IFS (C-IFS) model in the pre-operational global forecasting system. C-IFS fully integrates the atmospheric chemistry in the already existing model for meteorology, aerosols and greenhouse gases, providing a much more consistent and efficient modelling system. This has been a major step in the development of the MACC global forecasting system and it will ensure more accurate and timely forecasts for our users in the future.

In the middle of September several European countries were surprised by measurements of high sulphur dioxide concentrations at ground level. The MACC-III assimilation and forecasting system provided support to the French authorities by showing the volcanic origin of the SO2. More on this can be found in the corresponding News article.
On 1 August MACC-II was succeeded by MACC-III. This new member of the series of MACC projects is funded through the European Union's H2020 programme and will run until 31 March 2015. By then it is expected that the Copernicus Atmosphere Monitoring Service will be ready to start the operational phase. Documents describing the status at the end of the MACC-II project can be found in this News article.
MACC-II has worked with media agency to produce a set of articles and two video news releases explaining how the MACC-II systems work and serve users, in particular in the field of air quality and solar energy applications. This strong communication effort has helped to promote MACC-II among a very wide audience. Links to all the articles and videos can be found on the MACC-III web site.

Service Developments

The dissemination of the regional model ensemble forecasts has been moved forward in time. The first 48 hours of the forecasts are now available before 07 UTC with the 49-72 and 73-96 hour forecasts following at 08 UTC and 09 UTC, respectively.

The global assimilation and forecasting system has been migrated to the new Cray supercomputer at ECMWF. This powerful computing system will allow running the MACC-III global forecasting system at higher resolution in the near-future.

Copernicus Atmosphere Monitoring Service

Negotiations between the European Centre for Medium-Range Weather Forecasts (ECMWF), co-ordinator of MACC-III, and the European Commission to establish a Delegation Agreement for the Copernicus Atmosphere Monitoring Service are progressing well. We will keep you informed as things develop further.
