OPTIMAL SAMPLER SITING FOR ATMOSPHERIC TRACER EXPERIMENTS TAKING INTOACCOUNT UNCERTAINTIES IN THE WIND-FIELD

The problem of sampling sites for atmospheric tracer experiments were considered in Fedorov and Pitovranov (working paper WP-85-65, Internat ional Institute for Applied Systems Analysis, Laxenburg, Austria, 1988 ). There it was assumed that the wind direction during an experimental tracer release could be accurately predetermined and would remain con stant for the duration of the experiment. In general, this assumption of a constant wind field is not met. In this work we develop an approa ch which overcomes this deficiency. The monitoring network design prob lem is considered for cases which include prior uncertain wind fields during a designed experiment.
