Today we performed again an early flight and took off at 9:30 local (13:30 UTC). 
The LIDAR quicklook from Deebles Point (picture on the right, thanks to MPI Hamburg!) looked very promising and indicated a lifted layer with enhanced depolarization ratio at ca. 2 km above sea level and another layer reaching from sea level to about 1 km. Since there were no clouds we decided to focus on these layers.
Close after takeoff the Helicopter turned towards our measurement area south of Grantley Adams International Airport (GAIA, picture below). On our way to the reserved area we performed a low level leg at about 800 ft above sea level, so ACTOS wa
s at about 300 ft. Afterwards, we ascended to 10000 ft to make a full vertical profile and stayed there for at least ten minutes. Thereafter, we started our "aerosol layer chasing" and performed several horizontal legs at 6000 ft, 2000 ft, 1500 ft and again a low level leg. The data will tell us, if we caught the different layers.
Unfortunately, HELIOS is still forced to stay on ground but today there were lots of cirrus clouds... Finally, although there were no clouds within our duration my first research flight was a very interesting one.
PS: Clouds are back and ACTOS is again airborne at the moment...
