Preliminary results from a campaign at Villum Research Station in spring 2016 were reported in the August issue of the Danish journal “Dansk Kemi”.

The atmospheric particles that constitute the Arctic Haze in spring in North Greenland are strongly hygroscopic. Their ability to absorb water from the air determines their size, and accordingly their ability to scatter and absorb light and influences their role in cloud formation - properties that affect regional climate.

A unique data set has been acquired during a campaign at Villum Research Station in April-May 2016, shedding light over the hygroscopic properties of Arctic Haze particles.

The research was conducted by Robert Lange and Andreas Massling, Department of Environmental Science, Aarhus University.
