  1. Envisat Validation Workshop ASAR Wave Mode: Introduction & Status Nicholas Walker

  2. Data Status Cal Val Status The agenda Topics

  3. Level 1: Clean version of level 1 algorithm implemented at PDS on 16th Nov Data fed into the Ifremer Collocation System Bad data removed from collocation system Level 2: The Level 2 operational processing algorithm will be delivered at the PDS today, 12/12/2002 To be installed next week Data Status

  4. Independent calibration constants converging Validation advanced No problems observed Behaves as expected Harald, 60-70 orbits, several thousand imagettes FINAL recommendations for parameter optimisation including changing look bandwidth Cal/Val Status Level 1

  5. Large scale validation & algorithm comparison not started Lack of routine production of Level 2 data Harald, 22 orbits collocated data No unexpected problems observed with limited data set Works perfectly in swell dominated areas Optimised in swell dominated areas Little more optimisation required for non swell dominated areas Cal/Val Status Level 2

  6. Harald Johnsen (NORUT) Optimisation of Level 1 products & preliminary validation of Level 2 products Bertrand Chapron, Fabrice Collard (Ifremer) Ocean geophysical features inferred from ASAR Frank Melger (ARGOSS) Preliminary performance of the WVS & WVW ASAR Wave products Susanne Lehner, Johannes Schulz-Stellenfleth (DLR) First results on wind speed & sea state measurements from ASAR Wave data Jean Michel Lefevre, Lotfi Aouf (Meteo France) Preliminary results on assimilation of level 2 products Daniele Hauser (CETP) The VALPARESO experiment, status & overview of the collected data set Agenda
