Mobile measuring instruments: Caught in flight

Methane (CH4) is one of the main causes of global warming, but the contribution of the individual methane sources is still not exactly known. Such…

What breath reveals: detecting diseases with infrared sensors / prestigious prize for chemists

'The body's metabolism is reflected in the compounds present in the exhaled breath. On the basis of minuscule molecules, which are chemically altered or…

Atmospheric research infrastructure ACTRIS to European updated research infrastructure roadmap

ESFRI led evaluation panels and working groups assessed in 2015 the candidate projects by their scientific excellence, pan-European relevance, socio-economic…

EU invests 10 million euros into a research infrastructure for aerosols, clouds and trace gases

A total of 31 partners from 21 European countries are participating in the “Aerosols, Clouds, and Trace gases Research Infrastructure” (ACTRIS-2). The Leibniz…

Laser sniffs out toxic gases from afar

Scientists have developed a way to sniff out tiny amounts of toxic gases — a whiff of nerve gas, for example, or a hint of a chemical spill — from up to one…

How pigeons may smell their way home

To navigate, birds require a ‘map’ (to tell them home is south, for example) and a ‘compass’ (to tell them where south is), with the sun and the Earth’s…

How the detergent of the atmosphere is regenerated

Hydroxyl (OH) radicals – known as the detergent of the atmosphere – decompose isoprene in the air. This leads to the creation of new OH radicals, which are…

Coastal Waters Produce Halogenated Organic Molecules that Exacerbate Stratospheric Ozone Depletion

Coastal waters of the tropical Western Pacific produce natural halogenated organic molecules involving chlorine, bromine and iodine atoms that may damage the…

Research aircraft Polar 5 returned from spring measurements in the high Arctic

Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the…
