The G-IV is scheduled to fly a synoptic surveillance mission today with a take-off time of 1730 UTC (1:30 local) from Barbados. It will land in MacDill Air Force Base, Tampa, FL after their eight hour mission. The jet will fly around Tropical Storm Erika and will be sample the upper level trough to northwest. The data collected from these types of flights helps us understand the atmospheric weather conditions that Erika may encounter. The data also goes into NOAA’s weather forecasts models to improve the track and intensity forecasts for Erika. Here is the proposed G-IV flight track. The dots along the flight track indicate the dropwindsonde launch locations.
