Another successful research day

Aeolus satellite track oveppass east of Sal Island at sun set, so we needed 2 hours to get there. We flew altitudes between 5000 and 10000 ft, half of the time in dark, before joined another RNAV approach at Sao Vicente. Another successfull research day well coordinated with French and German Falcons and Lidar ground teams in Sao Vicente.
