  • 4th CCI collocation Meeting

    Ozone_cci Phase 2 Objectives

    Michel Van Roozendael and

    Ozone_cci team

    ESA/ESRIN, Frascati, Italy 4-6 February 2014

  • WMO O3 assessment 2014 •  Profile trends in WMO Ozone Assessment 2014

    •  Chapter 2: Global Ozone (Co-authors: M. Weber, J. Urban; contributing authors: R. van der A, M. Coldewey-Egbers, D. Loyola)

    •  Chapter 3: Polar Ozone (Lead author: M. Dameris; contributing authors: R. van der A, M. Weber)

    2001-2011

  • Ozone_cci team in Phase-2 3 2 EO Science Teams EOST-1 (Nadir) EOST-2 (Limb)

    VALT (Validation) CRG (Climate

    Research) SET (System Engineering)

  • Tropospheric

    Team organisation in Phase-2

  • Overall organisation concept

  • Planned Improvements in Phase-2

    Ø  Consolidation of ozone products portfolio à longer time-series

    Ø  Continued improvement of retrieval algorithms for nadir UV sensors à soft calibrations, cloud correction scheme, add OMI (and OMPS), harmonise columns and profiles (one single nadir EOST).

    Ø  Include IASI instrument (improved information content in UTLS).

    Ø  New focus on tropospheric data products, using 4 different approaches à nadir profiles (UV and TIR), CCD, limb-nadir matching, assimilation

    Ø  Extend altitude range of limb products à UTLS and mesosphere

    Ø  Link/merge European data sets to historical US data series.

  • Plans for nadir sensors •  EOST-1 & 2 merged into one single nadir EOST •  IASI added to UV sensors •  Year-1: Consolidation of CRDP

    Ø  Full processing GOME, SCIA, GOME-2 profiles Ø  Extended total column processing to OMI Ø  Adapt IASI FORLI scheme for CCI consistency

    •  Year-2: New algorithms Ø  Improve soft calibrations for columns and profiles Ø  Improve consistency of column/profile algorithms, incl. clouds Ø  Improve data assimilation schemes (ingest all nadir sensors)

    •  Year-3: Final (re)processing Ø  Complete reprocessing GOME, SCIA, GOME-2, OMI, IASI Ø  Merge/ assimilate full CCI and NASA data series

  • Plans for limb sensors (I) •  Year-1: Continuation and consolidation of CRDP

    –  Reprocessing of data/new data versions –  Update of HARMOZ and other L3 data à “covering all

    years” •  Year-2: Development of new algorithms

    –  Improvements of Level 3 data / Lifetime data record –  Special UTLS datasets (e.g. tropopause referenced

    datasets) –  Extension into the mesosphere (diurnal/daytime variation) –  Tropospheric ozone (e.g. limb-nadir matching) and

    comparison w/ other data

  • Plans for limb sensors (II) •  Year-3: Final processing and inclusion of US

    sensors –  Final processing of L3 datasets (stratosphere,

    mesosphere, troposphere) –  Updated level 3 and merged data including US

    sensors (HALOE, SAGEs, MLS, OMPS) –  Inclusion of mesospheric data in the merged data –  Trends and variability studies

  • Troposphere/UTLS developments

    •  TWG: Tropospheric Working Group •  Involves EOST, VALT and CRG teams •  Coordinates development of new tropospheric products,

    provides forum for exchange between teams •  5 different approaches to tropospheric product

    development planned in Phase-2: Ø  OE nadir profiling (UV, TIR, optional combined UV/TIR)

    Ø  Tropical tropospheric ozone based on cloud clearing (CCD) Ø  Limb-nadir matching approach Ø  Tropospheric ozone from assimilated nadir fields

    Ø  Special UTLS (tropopause-referenced limb product)

  • Processing system in Phase-2

    Main features Ø  flexible harmonized

    distributed and scalable system.

    Ø  easy way to integrate algorithm improvements.

    Ø  acceleration of reprocessing campaigns

    Ø  configuration management Ø  standardised validation

    routines Ø  product access capability

  • CRG - Evaluation and prediction

    Satellite data

    E39C-A „free running“

    Dameris and Loyola, 2011

  • CRG outlook for phase-2 •  Links to international activities:

    Ø  WCRP Coupled Model Intercomparison Project Phase 5 (CMIP5); ü  IPCC 5th assessment report (2013); Ø  SPARC/IGAC Chemistry-Climate Model Initiative (CCMI); ü  UNEP/WMO Scientific Assessment of Ozone Depletion: 2014.

    •  Use data available from climate, chemistry-climate (CCM) and chemistry-transport model (CTM) simulations: Ø  For example: CCMI Ref-C1SD* (1980-2012) ü  Analyses of short-term fluctuations and long-term trends; ü  Among others: column versus profile trends;

    •  Contribution of CRG to establish consistent ECVs Ø  confrontation of multiple ECV parameters to the output of the Chemistry-

    Climate Models operated by the Ozone_cci CRG
