Data Status Level 1: Clean version of level 1 algorithm implemented at PDS on

Data Status Level 1: Clean version of level 1 algorithm implemented at PDS on 16 th 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 Envisat Validation Workshop, ESRIN – 9 -13 December 2002 Page 3

Cal/Val Status Level 1 • Independent calibration constants converging Validation advanced No problems observed

Cal/Val Status Level 1 • 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 • • Envisat Validation Workshop, ESRIN – 9 -13 December 2002 Page 4

Cal/Val Status Level 2 1. Large scale validation & algorithm comparison not started 2.

Cal/Val Status Level 2 1. Large scale validation & algorithm comparison not started 2. Lack of routine production of Level 2 data 3. Harald, 22 orbits collocated data 4. No unexpected problems observed with limited data set 5. Works perfectly in swell dominated areas 6. Optimised in swell dominated areas 7. Little more optimisation required for non swell dominated areas Envisat Validation Workshop, ESRIN – 9 -13 December 2002 Page 5
