Presentation Transcript

  1. Aerosol_cci Phase 2 Datasets, applications, plans Thomas Holzer-Popp (DLR),Gerrit de Leeuw (FMI & UHEL), & the Aerosol_cci team

  2. Overview • Available datasets • ATSR-2 / AATSR 17 years / 3 algorithms • Validation ongoing • Full validation / one algorithm • GOMOS 10 years stratospheric extinction profiles • Validation ongoing • Different resolution on user request • IASI round robin datasets 2013 / 4 algorithms • Evaluation started • POLDER GRASP multi-pixel algorithm as reference 2008 • Plans in year 2 • Full cycle: validation, improvement, second full re-processing • 4 internal usercasestudies • MACC assimilation • AEROSAT inter-comparison (-> GEWEX aerosolassessmentphase 2) • Consistencyanalysiswithother CCI ECVs

  3. ATSR time series Evaluation report

  4. Uncertainties

  5. Anomalies Indonesian fires Siberian fires

  6. ”Trends”

  7. Validationvs AERONET L2 data: ±30 min, 35 km from AERONET stations ATSR-2 (1995-2003) AATSR (2002-2012)

  8. Differences to AERONET 2008

  9. Consistency: Overlap ATSR

  10. Stability vs. AERONET L3 (1x1 deg) – selected sites

  11. GOMOS / stratosphere GOMOS time series version GOMOS_AERGOM.v.2.14

  12. Temporal resolution New time series with adapted grid (v2.15) (5°latitude x 60° longitude x 1 km altitude x 5 days)

  13. IASI June 2013 datasets

  14. PARASOL / GRASP as reference Beiging Oklahoma Banizoumbou Mongu • 4 selected regions (1200 km x 1200 km) + Africa • 1 year (2008) of POLDER-3 data processing with GRASP • Banizoumbou: • Surface: Grassland. Aerosol: Coarse mode is dominated (dust). • Mongu: • Surface: Savanna. Aerosol: Fine mode is dominated (biomass burning). • Beijing: • Surface: Urban. Aerosol: Fine and Coarse modes (industrial/dust). • Cart_Site (Oklahoma): • Surface: Grassland. Aerosol: Fine and Coarse modes (rural).

  15. New in P2: case studies simulated regional aerosol direct radiative forcing (Kinne et al., 2013) EMAC moldel radiative forcing of stratospheric aerosol (Brühl et al., 2012/3 AAI record for West-Africa (Tilstra et al., 2011). Red GOME-1, Brown SCIAMACHY blue GOME-2A Changes in liquid water path due to anthropogenic aerosol (ECHAM6-HAM2; Lohmann, et al. 2010)

  16. MACC-III assimilation experiment (1 year) No assim AATSR MODIS MOD+ATS

  17. 3rd AEROSAT meeting ESA / Frascati 8+9 October 2015 in associationwith AEROCOM and CCMI -> time forinteractionwithmodelers
