Overview
 AirDat LLC has developed and deployed a proprietary atmospheric
observing system called TAMDAR (Tropospheric Airborne
Meteorological Data Reporting)
 The TAMDAR system delivers a unique real-time high resolution
data stream for improved atmospheric analysis and weather
forecasting
 Key components of the system include an aircraft mounted sensor,
dedicated global satcom, and ground processing systems
 Our satcom solution provides real-time global tracking of aircraft, as
well as voice and data communication with each aircraft at all times
 This real-time global communication capability is flexible, and allows
retrieval of aircraft performance/systems information
 The system has been in operation on commercial aircraft since 2004
