6. Near-real-time

7. Meteorological observations60 50 40 30 20 10

8. Atmospheric Composition
Sbuv 17, 18 and 19 only; MOPITT CO active in flv2; OMI NO2 active in flv2; GOME-2 SO2 passive in flv2; OMI SO2 active in flv2; MIPAS O3 active in flv2; MIPAS passive in f93i

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

10. Atmospheric Composition
Sbuv 17, 18 and 19 only; MOPITT CO active in flv2; OMI NO2 active in flv2; GOME-2 SO2 passive in flv2; OMI SO2 active in flv2; MIPAS O3 active in flv2; MIPAS passive in f93i

11. NRT production
MACC has continuously delivered daily near-real-time analyses and forecasts. Significant MACC developments are in place for first MACC-II upgrade.

12. Use of global NRT production
Boundary condition server
RAQ
WMO SDS-WAS

13. 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
Dual-mode aerosol
Aerosol lidar data

14. Delayed-mode

15. 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.

16. 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.

18. Reanalysis

19. Reanalysis

20. 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)

21. Global data server users
Reanalysis data has been downloaded by users around the world.

22. 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

23. 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.

24. Volcanic SO2
The assimilation of OMI SO2 data produces a plume that is confirmed by the IASI SO2 detection.

25. Global services

26. Web site
Web server distributed over MACC partners. Thousands of plots are generated each day.

27. Web site use 2011

28. Monitoring/verification
Input data is monitored and output data is continuously checked against independent observations.
