Macrophysical properties and a climatology of Arctic coastal fog in East Greenland
Arctic summer fog is a major transportation hazard and has implications for the cryospheric energy balance. In this thesis, the climatology and macrophysical properties of fog along the coast of East Greenland are explored, and local to mesoscale environmental conditions studied to explain regional...

Arctic summer fog is a major transportation hazard and has implications for the cryospheric energy balance.
