Accuracy of alert systems to detect environmental disasters based on remote sensing satellite observations.

摘要

Monitoring of oil and gas spill together with the control of pollution in oil and gas plants are key features for the security of oil and gas installations, for human health, air quality control and ultimately for the development of effective control strategies. Advances in remote sensing technologies can help to identify parties potentially responsible for pollution and to identify minor spills before they cause widespread damage. However, no single sensor has the capability to provide all the needed information, and combinations of sensors are currently used for monitoring and alert. Integrated systems, including ground based, airborne and space borne systems are the most promising candidates for efficient future contingency and alert plans. In particular, Doppler Wind lidar profiles can give a unique set of information to improve the operational use of other sensors in the frame of oil spill response. Oil companies and shipping operators are responsible for controlling spilled oil and cleaning polluted areas. In the event of an oil spill, information about the size and extent of the spill is critical to assist the government and industry in oil spill contingency planning and reducing economic losses
