SUMMARY of CONCLUSIONS
The main conclusions of the workshop are recalled
below. For more details refer to the relater splinter sessions
1. Salinity
-
update Klein & Swift
-
find 3 areas for cal/val
-
improved modelling (ITT studies)
-
assess accurately wind effect
-
work in warm (tropical pacific programme) and cold
(Nowegian sea) areas
2. Land
-
improve modelling of forest
-
address mixed pixels issue
-
influence of roughness and rugged terrain
-
Impact of snow, dew and frost
3. Image reconstruction
-
investigate stokes parameters
(dual or full pol)
-
potential error sources
-
calibration on sun/moon
-
Gaps in existing simulator
-
build reference scenarios
-
mandatory studies:
-
Develop hardware and simulator elements
-
more work on reconstriuction algorithms is required
-
make an instrument model available
-
build images for comparison of resampling procedures
4. Simulator
-
important to assess
instrument and ground segment
-
make a real end to end simulator
-
correct deficiencies and gaps in forward models (will
require work on modelling and campaigns) WS, foam, angular behaviour
-
forward algorithms:
-
do we have all we need (texture, roughness, ...)
-
retrieval matched to direct model
-
models should be very fast
-
need global maps
-
Tau-Omega model is robust and viable, it should be
used
5. Cal Val activities
-
moon an sun calibration
-
constant scene, "realistic" scene, fabricated scene
-
area well documented
-
Ice sheets
6. Burning issues
-
what is the range of view angles across scan necessary
and how to formulate it to the industry
-
dwell time and radiometric specifications
-
Reconstruction make info on instrument available
-
Resampling issues and pixel optimisation
-
Demonstrator
-
Cal Val and vicarious calibration
-
definitions of resolution and swaths
-
need for full pol and importance of ambiguities
