  1. COST ASSET ASSET (ASSimilation of Envisat data) W.A. Lahoz DARC, Reading, UK http://darc.nerc.ac.uk/asset Thanks to ASSET partners for plots COST Action #723

  2. COST ASSET • What is it? • Aims • Partners • Achievements • Examples • Future work COST Action #723

  3. COST ASSET WHAT IS IT?: • FV EU programme: EVK2-CT-2002-00137 • 36 months (Jan 2003-Dec 2005) • 13 partners (10 contractors, 3 assistant contractors) • U. Reading co-ordinator • 1,766,324 Euros COST Action #723

  4. COST ASSET PARTNERS: • Contractors: U. Reading, MF-GAME, ECMWF, KNMI, UPMC, BIRA-IASB, UKOELN, CNR.IFAC, NILU, CNRS-GAME • Assistant contractors: Met Office, IMK Karlsruhe, CERFACS • 7 countries (UK, France, The Netherlands, Belgium, Germany, Italy, Norway) • Heritage: DARE, SODA COST Action #723

  5. COST ASSET AIMS: Exploit & develop EO data to: • Develop European capability for chemical/UV forecasting Assess strategies for exploiting research satellite data by NWP systems • Provide analyses for coupled/chemistry studies Study distribution & variability of chemical species by exploiting research satellite data COST Action #723

  6. COST ASSET ACHIEVEMENTS: • Envisat data assimilated into NWP & photochemical models. QC-datasets incorporating Envisat data produced. Special contribution to studies of Sep 2002 SH major warming. • Envisat data evaluated using DA techniques. Information on data quality communicated to Envisat cal-val teams. • ASSET PIs lectured at 1st Envisat Data Assimilation Summer School held at ESRIN August 2003. TRAINING • ASSET database set up at NILU. Repository of datasets produced by ASSET project. COST Action #723
