Atmospheric Composition

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

Atmospheric Composition

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 Boundary condition server RAQ WMO SDS-WAS

Developments • Dual-mode aerosol • Capability to assimilate CALIPSO aerosol lidar data • Changes in ozone bias correction (MLS added as anchor) Dual-mode aerosol • Combined assimilation of IASI and MOPITT CO • Assimilation of OMI SO 2 to detect volcanic ash plumes Aerosol lidar data

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 CH 4 and CO 2.

Delayed-mode CO 2 CH 4 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 • T 255 L 60 = 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 (Var. BC)

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 SO 2 Significant progress has been made in the simulation and data assimilation of volcanic ash plumes. The AOD anomaly is complemented by a SO 2 plume through the assimilation of OMI data.

Volcanic SO 2 The assimilation of OMI SO 2 data produces a plume that is confirmed by the IASI SO 2 detection.

GLOBAL SERVICES

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 subprojects. 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
