Depending on the position of the Sun, the time of day and various other factors, the thin, high cirrus clouds over the Arctic have a predominantly warming effect. So far, however, almost no cirrus cloud measurements have been conducted at high latitudes, and climate models do not take these into account to a sufficient degree. […]

Wie sehr belasten Flugzeuge die Atmosphäre? DLR-Forscher nutzen die in Corona-Zeiten klare Luft, um es mit Messflügen herauszufinden. Christiane Voigt hetzt aus dem Hangar über die Betonfläche. Die Sonne steht tief und blendet, Lärm dröhnt über das Rollfeld. Sie muss schreien, um die neue Lage mit der Crew zu klären. Eigentlich war alles auf die

Der Corona-Shutdown war fraglos gut für die Luftqualität in Deutschland, eines der sichtbarsten Merkmale dafür: der unglaublich blaue Himmel in den vergangenen Wochen. Einen der Hauptgründe dafür benennen nun Wissenschaftler des Mainzer Max-Planck-Instituts: Das Fehlen der Kondensstreifen, weil die Luftfahrt am Boden lag. Genau dafür interessiert sich nun die Forschungsmission „Bluesky“: Mit einem Forschungsflieger wurden
Activities in congested urban areas all over the world were reduced this spring as a result of the COVID-19 pandemic. Only a few aircraft have continued to fly. As such, Earth’s atmosphere is significantly less polluted by emissions from human transport and industrial activities than it was previously. In the BLUESKY mission, scientists are investigating how clean
Two research aircraft investigate reduced concentrations of pollutants in the air The COVID-19 pandemic is not only affecting almost every aspect of our daily lives, but also the environment. A German team, led by the Max Planck Institute for Chemistry and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), now wants to

The SouthTRAC measurement campaign with the German research aircraft HALO was successfully performed in the region of South America and the Antarctic Peninsula end of 2019. This region is a hotspot of middle atmospheric gravity waves. An overview and first results of the data analysis were presented to the international community by members of our matrix group „Middle
Researchers solve puzzle of how mountain-generated atmospheric waves wind up in hot spot The Southern Ocean is famously stormy, home to waves taller than telephone poles. Yet 50 kilometers overhead, the weather is just as tempestuous, if less obviously so. Powerful waves in the air break and crash, dumping energy into the stratosphere and disrupting

The EUREC4A field study is aimed at solving one of the great mysteries in relation to climate change When it comes to predicting the extent of global warming by the end of the century, clouds are one of the greatest uncertainty factors. Cumulus clouds in lower layers of the atmosphere, reflect sunlight, thereby cooling the

From 20 January through 20 February 2020, the EUREC4A (Elucidating the role of clouds-circulation coupling in climate) field study will investigate trade wind clouds in the Tropical Atlantic. EUREC4A is a French-German initiated field study led by Prof Bjorn Stevens, Director at the Max Planck Institute for Meteorology (MPI-M) and head of the department “The
KIT, DLR, FZJ, and the Universities of Mainz and Frankfurt coordinate measurement campaign with the HALO research aircraft to study the southern atmosphere and its impacts on climate change Business Announcement Karlsruher Institut für Technologie (KIT) Trace gases, such as ozone and water vapor, are effective greenhouse gases and play an important role in climate
