Investigation of microclimate and spatio-temporal structure

• f surface thermal inversions

in the winter conditions of the Arctic (Apatity-case study)

CITES-2019, May 26 – June 6, Moscow, Russia

Motivation

Boundary layer inversions are closely connected with urban air quality

Apatity, Russia Fairbanks, USA

Field measurements
