Abstract:
A wind deceleration and protective shroud that provides representative samples of ambient aerosols to an environmental continuous air monitor (ECAM) comprising:a cylindrical enclosure having a first end and a second end, said second end being mounted to an input on said ECAM, said cylindrical enclosure defining at least three apertures located radially about its periphery; at least three nozzles having first and second ends, said first end extending into said cylindrical enclosure through each of said at least three aperture and said second end open to receive ambient air flows and direct said air flows upward through said cylindrical enclosure; a sloped platform located inside said cylindrical enclosure supporting said first end of said at least three nozzles and causing any moisture entering through said at least three nozzles to drain out through said at three one nozzles; wherein said flow of air creates a cyclonic flow up through said cylindrical enclosure until said flow of air reaches said first end of said cylindrical enclosure and is directed downward to said input of said ECAM.
