Flying in coordination – NOAA’s G-IV jet and NASA’s Global Hawk

NOAA’s G-IV jet and NASA’s Global Hawk are currently flying a coordinated mission over the Gulf of Mexico. The purpose of this mission is to compare measurements from the GPS dropwindsondes that are launched from the Global Hawk against the dropwindsondes launched from the G-IV jet. This test allows us to check the accuracy of the instruments. Below is the proposed flight track for the jet. The Global Hawk will over over the G-IV doing the same flight pattern. The green dots denote the dropwindsonde locations. The red dots on the map represent the locations where weather balloons are launched twice a day.
