Meteorological observations
Atmospheric Composition
Planned → passive → active
passiveactive
From planned to active for MOPITT CO observations
The global system produces daily plots of observation-model difference statistics
Time series and geographical plots are generated to monitor the input data, but also to provide feedback to data providers.

NRT production
MACC has continuously delivered daily near-real-time analyses and forecasts. Significant MACC developments are in place for first MACC-II upgrade.
Use of global NRT production
RAQBoundary condition server
WMO SDS-WAS
Developments
• Dual-mode aerosol
• Capability to assimilate CALIPSO aerosol lidar data
• Changes in ozone bias correction (MLS added as anchor)
• Combined assimilation of IASI and MOPITT CO
• Assimilation of OMI SO2 to detect volcanic ash plumes

DELAYED-MODE
Delayed Mode
The aim and challenge of the delayed-mode run is to provide optimal analyzed fields to be used in flux inversions or as boundary conditions for regional studies.A secondary aim is to support development of new retrievals of CH4 and CO2.
Delayed-mode
CO2 CH4
A significant amount of the synoptic variability of the greenhouse gases is driven by the meteorology.
However, the surface fluxes drive the signature of low and high concentrations.

REANALYSIS
Reanalysis
Reanalysis
• 2003 – 2010
• T255L60 = 80 km on 60 levels
• Coupled to MOZART chemical transport model
• Aerosols, reactive gases, and greenhouse gases on top of meteorology
• New emissions (anthropogenic, fires, lightning)
• Use of Variational Bias Correction (VarBC)
Global data server users
Reanalysis data has been downloaded by users around the world.
State of the Climate
Total AOD anomaly 2011 AOD anomaly for biomass burning SON 2011
The aerosol reanalysis has earned its place in the State of the Climate of the American Meteorological Society
Volcanic SO2
Significant progress has been made in the simulation and data assimilation of volcanic ash plumes. The AOD anomaly is complemented by a SO2 plume through the assimilation of OMI data.
Volcanic SO2
The assimilation of OMI SO2 data produces a plume that is confirmed by the IASI SO2 detection.
GLOBAL SERVICES
Web site
Web server distributed over MACC partners. Thousands of plots are generated each day.
Web site use 2011
Monitoring/verification
Input data is monitored and output data is continuously checked against independent observations.
GDA
Changes compared to G-IDAS
• More interaction between GDA and other sub-projects. ECMWF personnel will work on GDA and the sub-project of their specialization
• Stronger focus on data acquisition, data dissemination, meta data development, web, …
• Put procedures in place for running a reliable operational global service
Plans
• GDA.1: Coordination• Coordination of GDA work• Coordination of interaction with other sub-projects• Coordination of interaction with ECMWF developments
• GDA.2: Integration of new developments• Model and data assimilation developments• Integrated global analysis and forecasting system• Adaptation to new input data streams• Adaptation to new output data streams• Interaction with external GMES-related research
developments
Plans
• GDA.3: Global production• Near-real-time production• Delayed-mode production• Reanalyses for atmospheric composition• Support for science community and space agencies
• GDA.4: Global services• Monitoring and verification• Product display, supply, and general web services• User support
