Ozone and meteorological boundary-layer conditions at Summit, Greenland, during 3-21 June 2000

摘要

The temporal and spatial distributions of boundary-layer ozone were studied during June 2000 at Summit, Greenland, using surface-level measurements and vertical profiling from a tethered balloon platform. Three weeks of continuous ozone surface data, 133 meteorological vertical profile data and 82 ozone vertical profile data sets were collected from the surface to a maximum altitude of 1400 m above ground. The lower atmosphere at Summit was characterized by the prevalence of strong stable conditions with strong surface temperature inversions. These inversions reversed to neutral to slightly unstable conditions between ～ 9.00 and 18.00 h local time with the formation of shallow mixing heights of ～ 70-250 m above the surface.
