  1. Data Exploitation and Modeling for the Upper Troposphere and Lower Stratospherewww.cost723.org

  2. Scope and Structure • Altitude region around the tropopause is crucial for earths energy balance (water vapor cooling below, ozone heating above). • Chemical, microphysical, and dynamical processes not well understood . • Model and data studies for the UTLS altitude region. • Assimilation as the central tool to consolidate models and observations. • 3 Workgroups for the 3 areas. • Common workshops for all workgroups. WG2 WG1 WG3

  3. Countries Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Finland, France, Germany, Greece, Italy, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, UK

  4. Chairmen and Working Groups • Chair: William Lahoz (University of Reading) • Vice-chair: Bernard Legras (LMD) WG1: Data and measurement techniques(S. Buehler) WG2: An assimilated ozone and humidity dataset(W. Lahoz) WG3: Assessing the state of the UTLS and understanding the relevant processes(B. Legras)

  5. Sofia Workshop What do I expect? Strengthening of links between Bulgaria and other European scientists Overview of WGs 1-3 Examples of COST 723 work Exploration of collaborations: between COST 723 partners; between COST 722 & 723 COST 722: “Short-range forecasting methods of fog, visibility & low clouds” Preparation for a new COST action: e.g. integration of in situ networks and satellite data (Nik Kaempfer)

  6. Data Exploitation and Modeling for the Upper Troposphere and Lower Stratospherewww.cost723.org WG1 Activities

  7. Overview • Focus on humidity measurements • Improvements of different techniques and intercomparisons • In Situ • Ground Based • Satellite • Summary and Conclusions

  8. In Situ • MOL Lindenberg (RS80, RS92) • FMI Sodankylä (LAUTLOS campaign)

  9. Ground Based • Uni Bern (Microwave) • CNR-IMAA Potenza (LIDAR) • CNR-ISAC Rome (LIDAR)

  10. Satellite • Chalmers Göteborg (Odin SMR) • HIPC Prague (Odin SMR isotopes) • Uni Bremen (AMSU-B)

  11. Summary and Conclusions • A lot of ongoing activities (19 publications so far on www.cost723.org/publications) • Intercomparisons give valuable insights • Inside a technique by different instruments • Across different techniques • A pity to stop the good collaboration now  Suggestion for a follow-up action

  12. WG2: An assimilated ozone and humidity dataset • Our role/goal: • DA used to incorporate novel observations (e.g. ozone & stratospheric water vapour in UTLS), & evaluate research satellite data (e.g. Envisat). • Incorporate chemical data (e.g. ozone, water vapour from Envisat) into DA systems.

  13. Activities: • How to incorporate chemistry? • GCM assimilation (DARC, Met Office, ECMWF; 3d-var, 4d-var) – linear chemistry • CTM assimilation (KNMI, BIRA-IASB, U. KÖLN, UPMC; var methods, variants of KF) • Coupled GCM/CTM assimilation (MF; 4d-var) • Links with ASSET EU project (http://www.darc.nerc.ac.uk/asset)

  14. Activities: • Envisat cal-val • GCM (MIPAS: DARC/Met Office, ECMWF) • CTM (SCIA/MIPAS/GOMOS: KNMI, BIRA-IASB, UPMC) • http://envisat.esa.int/workshops/acve2/presentations • Ozone intercomparison project • ASSET partners • Paper submitted to ACPD: Geer et al. (2006), accepted • http://darc.nerc.ac.uk/asset

  15. What comes from these studies: key ideas in chemical DA • Ozone DA key driver in NWP & chemical models; not as much benefit as originally hoped in NWP • Key reason: relatively poor information content of ozone data available from current operational satellites -> Need more data (IASI, GOME-2,…) • Important area for NWP & chemical model DA: estimation of B • Needs to take account of physical & chemical principles & statistical data • One of biggest challenges in DA • Bias an important issue in DA -> estimation of biases a major challenge • Observations & models confronted to identify & attribute biases • Implementation of bias correction schemes active field of research

  16. Model deficiencies in transport & chemistry limit value of DA • V. difficult for assimilated data to represent processes on timescales much longer than typical assimilation cycle – O(weeks to months) • Expanding area for future DA activities is likely to be air quality • Experience gained in stratospheric chemical DA -> starting point for tackling technical problems associated of tropospheric chemical DA • Currently a wealth of constituent data from research satellites • Danger that this will diminish just as DA techniques to exploit those data reaching maturity -> What happens after Envisat & Eos Aura?

  17. Finally… • DA invaluable for use of stratospheric constituent measurements: • Fills gaps between observations • Allows use of heterogeneous measurements • Numerical model -> information to be propagated forward in time: combination of measurements available at different times & locations • Properly applied, DA can add value to observations & models, compared to information that each can supply on their own • DA underpins evaluation of impact of current observation types using OSEs, and future global observing system using OSSEs • DA ADDS VALUE • BUT, for proper use, limitations must be borne in mind

  18. Achievements: • Assimilation of Envisat data & cal-val • Intercomparison of ozone analyses • Address complexity of chemistry for DA • Ozone forecasts (stratosphere/troposphere) • Publications • Summer schools (lectures & organization) • Invited presentations at international meetings

  19. Summary • COST 723 WG2 is on a good track. • A lot of work via ASSET (Envisat) • Links with SPARC community (workshop in Oct 2006) • Plans for Eos Aura • New COST action?: integration between in situ network and satellite data
