TAMDAR v Radiosonde • For the first look we manually searched and sorted TAMDAR data and operational radiosonde ascents for comparison with the RSKOMP radiosonde comparison software. • Radiosonde ascents were selected from stations that were closely located to airports where aircraft fitted with TAMDAR units operate, • and sonde ascents chosen that were within an hour of take off or landing.
