In Iceland you hear one phrase very often: 'petta reddast', which can be translated as "it will all work out okay". With that in mind, we started planning the flight to have a closer look at strong changes in the horizontal and vertical gradients of the wind speeds in the atmosphere, which is one of the key objectives of the ADM-Aeolus WindVal campaign.

When operating from Iceland, the ideal target region for such an endeavour is in or near a jet stream (fast flowing current in the atmosphere with a meandering shape) over the North Atlantic that is within range of the aircraft. The situation on Friday 15 May 2015 offered a great opportunity to address this aim and coordinate with the NASA DC-8 to observe strong jet stream winds. We have total of four wind lidar systems on the two aircraft, the DC-8 and DLR’s Falcon. read more
