Spredning af lugt fra svinestalde. Meteorologi- og Lidar feltmålinger fra fuldskala tracerdiffusionsforsøg fra stald ved Roager i juni 1999 og 2000

摘要

In June 1999 and in July 2000 Risø National Laboratory performed a series of full scale field trials with joint tracer gas and aerosol plumes, together with the National Committee for Pig Production (DS), and the National Environmental Research Institute(NERI). The purpose was to study and to find ways to mitigate the fluctuating odour transmissions n the immediate surroundings (less than 300 meters) of a big Danish Pig fattening production unit. The experiments were performed from three differentventing duct heights on the roof in order to intercompare three different roof-based venting strategies. This data report contains 1. Local micrometeorological wind and temperature measurements from an In situ placed sonic anemometer 2. Description ofthree different sets of venting ducts 3. Generation of artificial aerosol plumes for the Lidar scanning 4. Lidar measurements of concentration fluctuations downstream from the pig farm. 5. Data processing, data interpretation, and conclusions (inDanish).
