Buoy Atmospheric Precipitation Sampler

Reliable automated collection and measurement of precipitation from moored buoys has been an elusive goal. Operation of open aperture collectors on ocean platforms is problematic, requiring constant human attention and intervention to prevent sea spray from contaminating the collected samples, and for dealing with freezing conditions in colder climates. Approaches are described that have the potential to automate these measurements over a six week period are proposed that extend the current state-of-the-art. We investigate sample segmentation and quality control screening for detection of sea salt, bird interference or other errors. The proposed system will provide continuous unattended collection and measurement of precipitation in all weather conditions, but will probably have to shut down during higher sea states. A low cost commercial system suitable for buoy deployment worldwide would be the result of this effort.
