The "age of stratospheric air" measures the speed of the global transport circulation in the stratosphere, which is crucial ...

A research team has uncovered surprising evidence of cross-border pollution reaching the Arctic, originating from an ...

Chinese researchers traced 2023 Icelandic volcanic emissions to Arctic smog, showing 80% of Ny-Ålesund’s sulfur dioxide came from the eruption. A research team led by Professors Si Fuqi and Yuhan Luo ...

In addition, there are many trace gases with much shorter lifetimes that are also on the agenda of this matrix group. Examples of these are ozone, nitrogen oxides, carbon monoxide, sulphur dioxide and ...

Illustration showing how trace gases are detected in the field using a mobile dual-frequency comb laser spectrometer. The spectrometer sits in the center of a circle which is ringed with ...

We develop and employ new and advanced optical technologies, including spectroscopic instruments for trace gas detection, and advanced algorithms for the next generation of ground-based and airborne ...

Researchers have developed a new portable Raman analyzer that can accurately measure very low concentrations of hydrogen gas ...

Atmospheric aerosols and clouds play important roles in determining the Earth’s climate. Trace gases and aerosols, constitute only a tiny fraction of the atmospheric mass, however they interfere with ...

The research team relied on advanced tools like the Environmental Trace Gases Monitoring Instrument, which is installed on two Chinese satellites. These satellites provide global daily scans ...
