The G-IV jet and the P3 aircraft are gearing up to fly and collect data in and around Karl. These flights provide us with insight to the evolution of Karl. The various instruments onboard the aircraft measure different atmospheric parameters that together give us a better picture of Karl. The G-IV will take off at 1:30PM (1730 UTC) followed by NOAA43 taking off at 2:00PM (1800 UTC). Below are the proposed flight tracks. The dots on the flight track (shown in green) represent the aircraft turn points. 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.
