5 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 5 Needs for improvement identified after Phase 1 AATSR / ATSR-2 Improvement for AOD > 0.2 Cloud masking / coverage Consistent uncertainties GOMOS Higher temporal resolution Higher coverage (weak stars)

6 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 6 Lv3 AOD vs AERONET 2008 (3 AATSR, MODIS)

7 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 7 ADV and SU are overall similar, with ORAC closer to MODIS. Regionally larger differences. ATSR-2 differences larger: under study 3 ATSR time series MODIS as reference

21 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 21 AAI regional time series

22 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 22 Conclusions Updated validated full mission time series available 3x ATSR AOD 17 year GOMOS stratospheric extinction 10 year New datasets added / round robin conducted IASI mineral dust Complementary datasets One more evolution cycle in 2015/2016 Test AATSR ensembles Further round robin exercises started AAOD (AAI, glint, mixing) layer height (O2A-band, IASI spectra)

23 Aerosol_cci > Thomas Holzer-Popp > ESA Living Planet Symposium, Bergen, 1 July 2010 slide 23 Cross ECV interactions In this session GHG / O3 -> explore aerosol correction in their retrieval Fire -> emission source of aerosol -> quantify surce term (mass fluxes, emission height) Other ECVs Clouds -> aerosol-clioud interaction studies (ACPC) OC, LC -> consistent surface model / aerosol model
