Avião especial realiza experimento sobre influência da floresta no clima da Amazônia MANAUS – Foi dada a largada para um grande experimento científico inédito na Amazônia, o chamado Cafe-Brazil – Chemistry of the Amazonian Atmosphere-Field Experiment in Brazil. Por dois meses, dezembro e janeiro, a atmosfera amazônica será analisada em detalhes, com um avião especial, cujos […]
Airborne Campaign Solves Parts of the Riddle of Clouds Cumulus clouds in trade-wind regions cover nearly 20 percent of our planet, producing a cooling effect. Until recently, it was assumed that global warming would reduce the surface covered by these clouds, amplifying the warming. However, a team around Dr. Raphaela Vogel from Universität Hamburg was

Heute wollen wir euch eine weitere Messkampagne vorstellen.Von dem Forschungsflugzeug HALO haben wir euch vor einiger Zeit schonmal berichtet (15.10.2021 & 05.11.2021). Damals im Zusammenhang mit der Messkampagne CIRRUS-HL.Diesmal war HALO nicht alleine unterwegs und hatte auch ein paar andere Geräte an Bord, aber eins nach dem anderen.Erstmal zum Kampagnen Namen HALO-(AC)³. Der erste Teil

Im Frühjahr 2022 fand die großangelegte Forschungskampagne HALO-(AC)³ in der Arktis ausgehend von Kiruna/Nordschweden und Ny-Ålesund/Spitzbergen statt. Mehr als 100 Wissenschaftlerinnen und Wissenschaftler, 3 Forschungsflugzeuge, Ballon und Bodenmessstationen waren im Einsatz, um die arktische Verstärkung, die immer rasantere Erwärmung der Arktis, in Zeiten des Klimawandels zu erforschen. Dabei schauten die Forschungsteams besonders auf die nordwärts gerichteten Warmlufteinschübe

Methane is produced by oil and gas extraction, coal mining, landfills, farming, wetlands, and thawing permafrost areas. But what are the exact numbers for each source? To find out, the HALO research aircraft has been operating over Canada – with researchers from the University of Bremen on board. “Methane in the Earth’s atmosphere is considered

Coal mining, oil and gas production, landfill and agriculture are all anthropogenic sources of the greenhouse gas methane, which is the second most important contributor to climate change after carbon dioxide. A methane molecule has an up to 86 times stronger climate impact than carbon dioxide. This is compounded by Earth’s large wetlands and thawing

TROPOS analysis: Wildfire smoke becomes increasingly important for climate models due to climate change The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the previous record wildfires in Canada
Lockdowns in early summer 2020 meant that the amount of soot in the atmosphere, which is harmful to the climate and to health, almost halved uring the first lockdown of the coronavirus pandemic, soot concentrations in the atmosphere over Western and Southern Europe almost halved. This is apparent from the comparison of two measurement campaigns carried

The goal of the HALO-(AC)3 campaign is to gain a better understanding of the air mass transformations within a Warm Air Intrusion (WAI) and Cold Air Outbreak (CAO). During a WAI, warm and moist air is transported into the Arctic. During a CAO cold and dry air is transported out of the Arctic. On the 11th of

What a successful day! P5, P6 and HALO had their first joint research flight on Sunday! If you ask yourself “What is HALO? And what is special about a joint flight?” then read on… First, let’s start with something you already know from the previous posts: P5 and P6 are polar aircraft, which participate in
