Flight plan#

  • The flight is planned to take off at 2024-08-13 19:15:00+00:00 UTC and land at 2024-08-13 22:45:00+00:00 UTC.

  • The HALO circle around the ATR-transects will be of radius 70 km centered at 15.5 N, 22.1 W.

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

  • opportunity to sample the Northern edge of the ITCZ

  • nighttime conditions (better range for Raman lidar)

  • not too far from METOP-B (23 UTC)
