Flight plan#

  • The flight is planned to take off at 2024-08-25 19:15:00+00:00 UTC and land at 2024-08-25 22:45:00+00:00 UTC.

  • The HALO circle around the ATR-transects will be of radius 70 km centered.

  • flight track designed for coordination with SAR on Sentinel-1 at 19:42 UTC (to study coherent structures near the ocean surface)

  • nighttime conditions (better range for Raman lidar)

  • two circle locations shown depending on whether ATC can accomodate requested changes
