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) Combined assimilation of IASI and MOPITT CO Assimilation of OMI SO2 to detect volcanic ash plumes Dual-mode aerosol 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 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.
