Ice clouds as a climate factor – research aircraft HALO examines cirrus clouds and vapour trails. Unanswered questions about the formation of clouds and their impact on the climate are currently setting limitations on the validity of global climate forecasts. To make a detailed analysis of the climate effects of natural ice clouds and the vapour trails created by air traffic, the HALO (High Altitude and LOng Range) research aircraft embarked on the first of a total of 12 measurement flights on 24 March 2014. For four weeks, as part of the ML-CIRRUS (Mid-Latitude Cirrus) mission, ice clouds (also known as 'cirrus') will be measured at altitudes of between eight and 14 kilometres above Europe and the North Atlantic.
