Today everything was well prepared, the helicopter was refueled and we could take off from the Concorde helipad at 09:15 local. A few cumulus clouds were in our operational area but we started with a profile up to 2200 m. The cloud situation was extremely inhomogeneous and it looked like every cloud had its own cloud base and to define cloud top was even more difficult. The cloud edges were very fuzzy and sometimes clouds nearly dissipated before we could penetrate them a second time. Finally, I let the pilots decide which cloud was best to sample since they have the better view from the cockpit. At the end we made two horizontal legs in 500 and 420 m above the ocean which was close to the lowest cloud base.
The picture shows the cloud situation from ACTOS' point of view - very small cumuli with diameters of maximal 200 m.
