Land Surface Processes (LSP) play a key role in the climate system. Monitoring and characterizing these processes, in particular those related to sustainable development, agricultural production, habitat, ecosystem and forest studies, and natural hazards from space requires state of the art physically-based algorithms and image analysis techniques to provide reliable and accurate information. Typical bio-geophysical variables include Leaf Area Index, Fraction of Absorbed Photosynthetically Active Radiation, surface albedo, biomass, height of canopy, surface temperature, or soil moisture, etc ... Land surface products are directly generated by space agencies and are now available to user communities. These scientific developments will, in turn, require a sustained program of calibration and validation on the ground, but will carry on a wide variety of new applications including those addressing climate changes (for instance, these new RS products permit the climate change or the carbon cycle communities to improve their models).
This symposium will focus on the following aspects:
1) Validation and accuracy of land surfaces parameters derived from remote sensing data:
- protocol & benchmarking methods (including calibration of data)
- inter-comparison of similar remote sensing products
- scale issues versus spatial resolution of remote sensing data
2) Evaluation of land surface products for environmental and global change studies.
- with in-situ measurements (scale issues etc...)
- Applications (assimilation and/or comparisons etc ...)
3a) Use of the remote sensing data in thematic analysis and environmental monitoring such as natural hazards over land surfaces (i.e., earthquakes)
3b) Use of the remote sensing data in thematic analysis and environmental monitoring such as:
- environment sustainability (i.e., limnology, terrestrial ice fields or fire detection and impacts)
- Ecosystem, habitat, forest and agriculture
4) Perspectives
- New techniques (or missions) for characterizing the environment/land surface processes
- Development of new tools (or missions) to propose other remote sensing data and products
