The research aircraft HALO (High Altitude and Long Range) is a joint initiative of German environmental and climate research institutions. HALO is funded by grants from the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), the Helmholtz Association, the Max Planck Society (MPG), the Leibniz Association, the Free State of Bavaria, and the Karlsruhe Institute for Technology (KIT), the Research Center Jülich and the German Aerospace Center (DLR).

HALO conducts scientific investigations of the earth's atmosphere. It enables measurements in atmospheric heights that are important for life on earth in a quality that has never been achieved before. The investigations significantly contribute to understanding for instance ozone chemistry and the exchange of air pollutants. HALO mainly carries out measurements in the troposphere and the lower stratosphere and is also used for earth observation.

Since the end of 2013, measurement flights have been taking place regularly, in which the MPI for Chemistry is significantly involved or which it coordinates. An example is the CAFE-Africa mission in 2018 that aimed at determining the impact of the massive emissions caused by biomass combustion in southern Africa to investigate the oxidation capacity of the atmosphere over the tropical and southern Atlantic.
