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.
The HALO research aircraft heralds a new chapter in the history of German atmospheric research and Earth observation.
In the icy environment high above the Arctic and working in close cooperation with other German research institutes, scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are going to investigate the complex processes involved in climate change and their impact on the polar atmosphere.
Thunderclouds over rainforests are an important element in the climate system. The DLR research aircraft HALO spent the period from the beginning of September to the beginning of October 2014 in Manaus, a city in the Brazilian state of Amazonas, measuring the emergence, development and properties of tropical clouds.
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.
