Weather conditions and seasonal variability of limited surface visibility at Greenland coastal locations
Abstract Adverse weather has been shown to be spatially and temporally variable across high‐latitude locations. The current study provides a unique investigation of limited surface visibility time periods at five coastal Greenland locations from 1979 to 2018 and identifies the coincident adverse wea...

Abstract Adverse weather has been shown to be spatially and temporally variable across high‐latitude locations.
