Forschungsflugzeug Halo auf Mission in der Arktis

Media Reports & Press Releases |

Um den Klimawandel in der Arktis besser zu verstehen, unterfliegt Halo den europäisch-japanischen Earthcare-Satelliten zum Vergleich von Messdaten. Die Arktis zählt zu den am stärksten vom Klimawandel betroffenen Regionen. Die Temperatur ist hier in den letzten Jahrzehnten etwa viermal so stark angestiegen wie im globalen Durchschnitt. Warum sich die Arktis so viel stärker erwärmt als […]

Successful first mission flight for ASCCI mission

HALO updates |

Today’s first long mission flight of HALO for the ASCCI mission went well. Landing was approx. 18:41 local and thus almost 9:40 hours flight time practically as planned. No major instrument problems were reported in the de-briefing. We will now continue with three ground days as planned and the transfer to Kiruna as a longer measurement flight

‘Cloud machine’: emissions from the Amazon Rainforest and electrical discharges create rain particles

Media Reports & Press Releases |

An international group of researchers, with the participation of Brazilians in particular, has succeeded for the first time in unraveling the physiochemical mechanism that explains the complex system of rain formation in the Amazon, which influences the global climate. It involves the production of aerosol nanoparticles, electrical discharges and chemical reactions at high altitudes that

Gas in the Amazon rainforest accelerates cloud formation

Media Reports & Press Releases |

Trees emit isoprene, which reacts with other molecules and increases the production of cloud condensation nuclei 100-fold A defense mechanism that has emerged and disappeared several times over the evolutionary history of different lines of plants, particularly trees in hot environments, plays a crucial role in Amazonia in one of the most important land climate

HALO mission integration ongoing

HALO updates |

Preparations for the next HALO mission are on the way. During the ASCCI campaign, scientists aim at improving their understanding of: 1. Inter-annual variability of Arctic lower stratospheric ozone depletion and the implications for radiative forcing and surface climate impacts of ozone recovery2. High latitude stratosphere-troposphere exchange and the structure of the high latitude tropopause3.

Above the Clouds: HALO Measurement Campaign Successfully Completed

Media Reports & Press Releases |

Over a period of more than three months, scientists have collected data on cloud formation in the Atlantic with the HALO research aircraft, and repeatedly performed flights underneath the EarthCARE satellite for joint measurements. This campaign, called PERCUSION, was led by the Max Planck Institute for Meteorology and the German Aerospace Center and has now

EarthCARE Validation im vollen Gange!

Media Reports & Press Releases |

Nachdem die ersten beiden Teile der groß angelegten Messkampagne PERCUSION/ORCESTRA unter Leitung des MPI in Hamburg und des DLR in Oberpfaffenhofen, auf Kap Verde und auf Barbados erfolgreich durchgeführt wurden, sammeln sich die Wissenschaftler erneut für den dritten und letzten Teil der Kampagne. Mit dem Blick voraus auf den noch verbleibenden Kampagnenteil mit der intensivierten EarthCARE Validation können die Wissenschaftler bereits einige Highlights verbuchen.
