Current web-based weather event and satellite data portals provide large amounts of data over a historical timeline. However, users of these portals often get access to data only through limited, pre-defined queries based on a strict set of criteria and event trajectories. Desirable capabilities, such as spatial-temporal analysis, efficient satellite data retrieval, and ad-hoc queries on trajectory data, are not available in these information systems and data archives. In this paper, the authors describe their current work on and progress in the development of a sophisticated moving objects database infrastructure designed primarily to allow ad-hoc querying of dynamic atmospheric events (e.g., hurricanes and storm systems) and the efficient retrieval of satellite (e.g, QuikSCAT, TRMM) measurements.
