SOBRINO, J. A.,received the M.S. and Ph. D. degrees from the University of Valencia, Spain, in 1986 and 1989, respectively, all in physics. He is Professor of Physics and Remote Sensing, University of Valencia, since 1994, and presently is leading the Global Change Unit (http://www.uv.es/ucg) at the Department of Thermodynamics, University of Valencia, Spain, and the international WATERMED project. His research interest include atmospheric correction in visible and infrared domains, the retrieval of emissivity and surface temperature from satellite images, and the development of remote sensing methods for land cover dynamic monitoring. Author of more than 50 papers and referee of several international remote sensing journals

SU, BOB, is a senior scientist in remote sensing and hydroclimatology. His current research focuses on remote sensing  and numerical modelling of land surface processes and interactions with the atmosphere, and applications in water, climate and environmental management. He has acted as project manager and co-investigator of several projects supported by the Dutch Remote Sensing Board, the Dutch Ministry of Agriculture, Nature and Fishery, the Royal Dutch Academy of Sciences and the European Space Agency (ESA). These projects include: Advanced Earth Observation-Land Surface Climate, NWP (Numerical Weather Prediction)-Microwave Soil Moisture, ENVISAT- Land Surface Processes, ENVISAT-Evaporation, ENVISAT-Sampling, Heat and Water Balance in Arid and Semi-Arid Regions, and ESA's Land Surface Processes and Interactions Mission, CHINA_CGMS: an information infrastructure for promoting efficient irrigation practices in the North China Plain and CHINA_DROUGHT: Drought monitoring and prediction over continental China. He is a member of American Geophysical Union (AGU), International Association of Hydrological Sciences (IAHS), IEEE Geoscience and remote sensing Society, Dutch Society of Earth Observation and Geo-information, and member of European Geophysical Society (EGS) and served as its secretary for remote sensing, Geo-information and data assimilation in 2001. He has published more than 140 papers in refereed journals and conference proceedings and acts as reviewers for several international journals (Remote Sensing of Environment, International Journal of Remote Sensing, IEEE Transactions on Geoscience and Remote Sensing, Physics and Chemistry of the Earth, Hydrological processes). Currently he is co-ordinator of the science team for the GMES Service Element: Service for Advanced Geo-information on Environmental Pressure and State – SAGE.

LI, ZHAO-LIANG, received the B.S. degree in photogrammetry in 1985 from WuHan Technical University of Surveying and Mapping, China, the M.S. degree in imaging processing and computer graphics in 1987, and his Ph.D. degree in terrestrial environmental physics in 1990, both from the University of Louis Pasteur, Strasbourg, France. Since 1992, he has been a research scientist at CNRS, Illkirch-Graffenstaden, France. He has participated in many national and international projects such as NASA funded MODIS, EC funded programs EFEDA, HAPEX-Sahel, REKLIP, WINTEX and ESA funded program LSPIM. He serves as referee of several international journals and is a member of several scientific committees. His main research activities are in radiative transfer simulation, modelling of the earth system, application of remote sensed data in land-surface-atmosphere interactions. He has published more than 25 papers in international referred journals on atmospheric corrections in visible to thermal infrared domains.
