How are TAMDAR observations collected?
Observations are taken at specified pressure altitude levels (remotely programmable by AirDat) as the aircraft takes off and climbs to cruise altitude. At cruise, observations are switched to a time-based protocol (also remotely programmable) and then switched back to pressure-based levels as the aircraft descends to land. As they are made, observations are transmitted to AirDat’s data center and are typically available for model assimilation or analysis within a minute of the time of observation.
