Workshop Concluded Successfully!
The workshop was a success, with the
participants very receptive and active in their participation
and discussion. Please follow the link button to the right or
click on the following to see materials presented at the
workshop (http://geo.obspm.fr/workshop/).
In addition to the development of a common emissivity modeling
framework, participants in the First International Workshop of
Remote Sensing and Modeling of Surface Properties recommended
the archival and documentation of all existing land surface
emissivity data bases from IR and microwave wavelengths at a
centralized website for public access for an efficient
intercomparison and evaluation of the modeled, satellite-derived,
and in situ emissivity estimates.
Subject of the
workshop
Remote sensing and modeling
of radiometric and geophysical surface properties,
including the impacts of assimilating
surface-sensitive measurements.
-
Microwave and infrared spectra and
all surface types are of interest:
This focused meeting will have no
parallel sessions and only oral sessions. The
workshop format will encourage open discourse with
plenty of time for questions, and
discussions.
Venue
The meeting will convene in
the 'salle Cassini' in the 'bâtiment
Perrault' on the campus of L'Observatoire de
Paris.
Registration
There will be a 50 Euro registration fee, payable in
cash either the Monday preceding the conference in the
salle Cassini from 4 - 6pm, or on Tuesday morning starting
at 8:45am. The registration fee will cover lunches at
the Observatoire for the 3 days, room costs, and coffee breaks.
Meeting topics
The following non-exhaustive list of
scientific topics is suggested:
- Description of methodologies to assimilate
surface-sensitive radiances in NWP centers (both
in operational and research modes), including
cloud screening approaches and surface
temperature handling.
- Description of emissivity/reflectivity models
(both MW and IR, over land, ocean, snow and ice),
used or usable in NWP frameworks.
- Description of available land emissivity
databases/atlases (MW and IR). Description of the
parameterization of angle and frequency
dependences.
- Intercomparison/validation of physical models
and directly retrieved emissivities (including
land, ocean, and ice surfaces).
- Synergistic use of physical models and
retrieval-based emissivities (for the
parameterization of the angle/frequency
dependence for instance).
- Document data assimilation impact studies
performed using surface-sensitive radiances (IR
and MW).
- Review the output fields available from
operational land surface modeling systems, and
target fields necessary for forward modeling of
infrared and microwave emissivities. Discuss
aggregation of global soil and vegetation
databases for use in emissivity modeling.
- Retrieval of land surface temperatures from
infrared and/or microwave observations and the
impact of the emissivity assumptions on these
estimates.

This workshop is sponsored by the l'Observatoire
de Paris and by the Satellite Meteorology and
Climatology Division (SMCD) of the NOAA/NESDIS
Office of Research and Applications.
