Technical Abstract: The international workshop on soil moisture monitoring, analysis and prediction for hydrometeorological applications was sponsored by the Global Energy and Water cycle Experiment (GEWEX) of the World Climate Research Program and the Biospheric Aspects of the Hydrologic Cycle (BAHC) of the International Geosphere-Biosphere Program. The primary aim for this workshop was to consider the potential for implementing a global system during this decade and to identify the priorities for the research needed to achieve such a global system. The workshop considered that a global system should provide measurements and/or estimates of volumetric soil water content on at least a daily basis at a 50-km resolution and at vertical resolutions consistent with vegetative rooting depths within the resolution grid. It was generally agreed that a global soil moisture monitoring system would be model based with the in-situ and remotely sensed dmeasurements used primarily for validation and evaluation of the model-derived fields. The consensus of the workshop participants was that a global system for soil moisture is needed and, furthermore, a rudimentary system could be implemented on an experimental basis with tools currently available. However, many future improvements were recommended as essential to make such a system successful and operational. Among the several workshop recommendations, it was strongly recommended that the development of a global model to produce model-derived estimates of soil moisture should be started immediately.
