Porpoise dives around cloud base

Today we performed (probably) our second last flight. After the low level leg at a height of 50 m (ACTOS height) above the sea, we started the profile up to 8000 ft (helicopter height). During this time almost all clouds in our measurement area disappeared. Only north of Ragged Point nice cumulus clouds were located above the sea with a cloud top at 6500 ft. So, we decided to chase these clouds. Afterwards, we flew back to our measurement area and investigated conditions around cloud base east of Ragged and Deebles Point. We started with a horizontal leg at a height of 3000 ft, followed by four porpoise flights between 1500 ft and 3000 ft and finished with a horizontal leg at 1500 ft (helicopter height). Before the last leg, the mini CCNC was switched to the scanning mode. We finished the flight with a low level leg above sea heading to the airport.
