    This is the comprehensive data report from a series of tracer experiment carried out in the Copenhagen area in 1978/79 under neutral and unstable atmospheric conditions. The report contains sulphurhexafluoride of tracer concentrations and meteorologicalmeasurements The tracer was released without buoyancy from a tower at a height of 115 meters and then collected 2-3 meters above ground-level at positions in up to three crosswind arcs of tracer sampling units, positioned 2-6 km from the point of release. Three consecutive 20 min averaged tracer concentrations were measured, allowing for a total sampling time of 1 hour. The site was mainly residential having a roughness length of 0.6 m. The meteorological measurements performed during the experimentsincluded standard measurements along the tower of tracer release as well as the three-dimensional wind velocity fluctuations at the height of release.
