One of the missions of CESBIO is to contribute to the development and utilization of Space-based observations of the Biosphere. CESBIO's contribution can be organized into three main categories :
1) The development of methods which use data from existing space instruments and the innovative use of these data :
it concerns :
- Improvement of data quality (corrections, calibration) based on the state of the art in measurement physics.
- Improvement of methods used to estimate the caracteristics and properties of the surface used in models, and/or increasing remotely sensed data use.
- Improvement of innovative methods which permit the computation of new quantities from existing instruments.
2) Innovative mission proposals or the participation in the definition of future missions
The CESBIO is from its origin source of proposals for new space missions dedicated to the observation of land surfaces.
- VENuS mission : (Vegetation and Environnement monitoring on a New Micro-Satellite).
- BIOMASS mission : Biomass Monitoring Mission for Carbon Assessment.
- The Living Planet Program : Soil Moisture and Ocean Salinity Mission (SMOS) and the following SMOS-next mission
- CESBIO is also very involved in the proposed space mission Mistigri
3) Airplane and ground-based instrumentation
In order to respond to these needs, the CESBIO is participating in the development of ground and airplane based sensors corresponding to a satellite instrument with the goal of developing algorithms for calibration or evaluation. Moreover, the CESBIO is participating in the definition and specification for developing and testing ground and airplane based simulators which are utilized by teams for projects in the laboratory.
CESBIO's contribution is primarely on the development and application of new ground based instrument concepts
