NOAA’s G-IV hurricane hunter jet is preparing for a research Tail Doppler Radar (TDR) mission around Joaquin. The proposed flight track is shown below. They will depart at 1:30PM local time from MacDill Air Force Base, Tampa, FL and fly a seven-hour mission. The goal of this flight is to collect data around Tropical Storm Joaquin. The G-IV will collect tail Doppler radar data that will help us understand the structure of Joaquin. The dots on the flight track (shown in green) represent the aircraft turn points and dropsonde locations. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.
