The concept for sensor web is to link together ground and space-based instruments to enable autonomous collaborative observation collections. These observations can be triggered via a variety of sources. Typically, scientific events of interest trigger observation campaigns in an ad hoc sensor constellation and supply multiple data acquisitions as rapidly as possible and in as much depth as possible in a given time period. This is accomplished through a seamless set of software and communications interactions in a system of linked sensors.

The next-generation science and exploration systems will employ new observation strategies that will use multiple sensors in a dynamic environment to provide high quality monitoring, self-consistent analyses and informed decision making. The sensor web experiments described herein provide a prototype to explore the nature of automation necessary to enable dynamic observing of Earth and other planetary phenomena. The tools being developed improve our ability to autonomously monitor multiple independent sensors and coordinate reactions to better observe the dynamic phenomena. These systems enable users to specify events of interest and how to react when an event is detected. The systems monitor streams of data to identify occurrences of the key events previously specified by the scientist/user. When an event occurs, the system autonomously coordinates the execution of the user-desired reactions between different sensors. The information can be used to rapidly respond to a variety of fast temporal events without human intervention.
