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 […]

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
Above the Clouds: HALO Measurement Campaign Successfully Completed Weiterlesen »
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.

From the beginning of August to the end of September the Meteorological Institute contributed to the HALO aircraft campaign PERCUSION. The cloud systems of the intertropical convergence zone were studied using the German research aircraft HALO from Cape Verde and Barbados islands, i.e. from both sides of the Atlantic, and with the new ESA satellite
The HALO research aircraft from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has successfully completed the first phase of its most challenging mission to date, in terms of flying and science, over Cabo Verde. Since the beginning of August 2024, HALO (the High Altitude and Long Range research aircraft) has been
MPI-M researchers and their partner institutions are currently performing atmospheric measurements over the equatorial Atlantic with eight coordinated measurement campaigns. They want to find out what controls the structure of the tropical rain belt, how it will change in the future and what this means for weather patterns. A variety of state-of-the-art research platforms are

Special features of the Arctic climate, such as the strong reflection of the sun’s rays off the light snow or the low position of the sun, amplify global warming in the Arctic. However, researchers are often faced with the challenge of modelling the underlying climatic processes in order to be able to provide reliable weather
Der erste Teil der groß angelegten Messkampagne PERCUSION/ORCHESTRA neigt sich dem Ende. Fast 4 Wochen war dabei das deutsche Forschungsflugzeug HALO auf den Kap Verden stationiert und hat dabei zahlreiche Daten gesammelt um die Instrumente des EarthCARE Satelliten validieren zu können. Dafür ist das Forschungsflugzeug HALO mit einer ähnlichen Payload bestückt, wie die EarthCARE-Payload. Für die Vergleichsmessungen werden dabei
