  Information - HS11.5 Soil moisture estimation using field instrumentation, remote sensing and modelling

Event Information
We invite presentations concerning soil moisture estimation, including remote sensing, field experiments, and land surface modelling. The technique of microwave remote sensing has made much progress toward its high potential to retrieve surface soil moisture at different scales. From local to landscape scales several field or aircraft experiments, PORTOS-91/93/96, SGP97/99, EUROSTARRS 2001, SMEX-02-04, SMOSREX and coSMOS-2005 were organized to improve our understanding of active and passive microwave soil moisture sensing, including the effects of soil roughness, vegetation, spatial heterogeneities, and topography. At continental scales several passive and active microwave space sensors, such as SMMR (1978-1987), AMSR(2002-), and ERS/SCAT (1992-2000) have already provide information on surface soil moisture. Further investigations in L-band passive microwave with SMOS (2008) and in active microwave with Metop/Ascat (2007) promise to open new possibilities in the quantification of the soil moisture from regional to global scales. Comparison between soil moisture simulated by land surface models, in situ observations, and remotely sensed soil moisture is also relevant to characterization of continental scale soil moisture dynamic (e.g., GSWP2). We encourage presentations related to soil moisture remote sensing, including field experiment and theoretical advances in microwave modelling; root zone soil moisture retrieval and soil moisture assimilation in land surface models; and inter-comparison and inter-validation between land surface models and remote sensing approaches.

Selected papers of this session will be invited to submit full-papers to a special issue “Remote Sensing in Hydrologic Sciences” of the Hydrology and Earth System Sciences (HESS) journal at or shortly after EGU08. Deadline for the submission of the full-papers is 31/05/2008. HESS is a peer-reviewed international journal and is listed in ISI.

Please do not forget to apply for support applications (note early deadline) and for Young Scientists’ Outstanding Poster Paper (YSOPP) awards.
