Summary

  • For the upcoming flight on Sunday:
    • Moist margins are still uncertain: island of dry air along the EarthCare track
    • Precipitation and high clouds to the south of the island of dry air
    • Safe idea would be to place the circles and waypoints to the south of 10 deg
    • Doldrums also located close to 10 deg
  • For future flights:
    • The arrival of a new easterly wave, makes the northern margin uncertain
