The new High Altitude and LOng Range Research Aircraft (HALO) research aircraft heralds a new chapter in the history of German atmospheric research and Earth observation. HALO is based on a Gulfstream G 550 ultra long range business jet. The combination of range, cruising altitude, payload and comprehensive instrumentation make the aircraft a globally unique research platform.

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 research aircraft embarked on the first of a total of 12 measurement flights on 24 March 2014.
Clouds can both warm and cool Earth's atmosphere. In current climate models, detailed conditions for cloud cover as a climatic factor are still not clearly understood. There is a shortage of precise measurements on how the water, humidity, ice particles and aerosols that form water droplets are distributed in towering cumulus clouds.
