Title: Radon, as a tracer for mixing height dynamics - an overview and RADO perspectives

Abstract: This paper analyses the various existing experiments using the natural isotope Radon – 222 in estimating the planetary boundary layer (PBL) dynamics and particularly the regional pollutants mixing height. The paper will propose an instrumental set-up in frame of RADO project (Romanian 3D Atmospheric Observatory) based on meteorological tower instrumentation (standard meteo station with 30 and 60 m measuring levels) supplemented by eddy covariance for extensive studies and using well established relationships for assessing mixing height from surface measurement. This will include also daytime comparisons with MAP3D (Mesoscale Air Pollution 3D model) simulations in Bucharest-Magurele station area. Finally LIDAR observations for PBL height validation will be used for development of local Radon tracing function. Further potential development of RADO will be argued.

Key words: Radon, surface emission, atmospheric tracer, planetary boundary layer
