  3. Deliverables

  4. Deliverables

  5. Milestones

  6. Near-real-time

  7. Meteorological observations 60 50 40 30 20 10 0

  8. Atmospheric Composition

  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

  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.

  17. CH4 assimilation in delayed-mode run GOSAT IASI SCIAMACHY

  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.

  29. GDA

  30. 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

  31. 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

  32. 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

  33. Exciting improvements

  35. Delayed-mode system Improved prior fluxes Satellite data Data Assimilation In-situ data Flux inversion Optimized fluxes Forward run Boundary conditions

  36. Optimized CO2 flux run

  37. Reanalysis • Continuation of MACC reanalysis for 2011 and 2012 • Focused short reanalyses using new ESA-CCI data sets • Interact with ECMWF Reanalysis group on future developments

  38. Web and data services • Redesign of web site • User-friendly interface for data • Operational data streams on ftp More routine monitoring and verification plots available for users and validation groups.
