788.11J Presentation “Atmospheric Observatory” Presented by Seyfettin Yasin Bilgin
The Main Idea Distributed networks of short-range radars offer the potential to observe winds and rainfall at high spatial resolution in volumes of the troposphere that are unobserved by today’s long-range weather radars. By scaling the wireless sensor network technologies upward and 30-km radar technologies downward OTG – Of The Grid radar and wireless radar network
The Main Achievements Source its prime power needs using energy harvesting (solar panels) rather than existing power infrastructure Transport its data and control communications via wireless ad-hoc communications network rather than existing network communication infrastructure Manage its energy consumption by adapting its functionality to the environmental conditions
The Challenges Trade off between sensitivity and time requirements 5 minutes intervals needed for tracking fast events Limited-sector scans instead of full volume surveillance
