Lidar measurements of the 2D cloud structure below the research aircraft
Cloud-free areas are shown in light blue and white. Everything from dark blue shows the clouds along the flight path, with the intensity of the backscattered light increasing from dark blue to dark red. The illustration highlights the complex structure and interplay of low clouds over the open ocean and ice clouds above. At the beginning of the flight path, the low clouds (height up to approximately two kilometres) are
clearly separated from the ice clouds (lower edge at approximately 2.5 kilometres). However, as the flight progresses, the upper edge of the deep clouds increases so that they are now directly connected to the overlying ice clouds.
