Meteorological and radiological measurements on fishing vessel
20 August 2021
The Hong Kong Observatory has been operating automatic weather stations and radiation monitoring stations at different locations of Hong Kong, most of them being over the land. In order to enhance the observation over the sea and extend the coverage of monitoring, the Observatory is conducting a trial in cooperation with a fisherman organization. A set of anemometer and radiation sensor was installed on a fishing vessel to measure enroute winds and radiation levels when the vessel traverses the Hong Kong waters and the northern part of the South China Sea. The measured data are transmitted back to the Headquarters in real-time using the latest satellite communication technology. Based on the performance of the trial, the Observatory will optimize the system and deploy it to more vessels to enhance its weather and radiation monitoring services.
