AB: A search has been conducted for near-surface ozone plumes extending roughly northeastward from New York City, by employing ozonesondes carried by a boat on western Long Island Sound. This water-borne search pattern avoids the local sources densely distributed on land in the suburban counties and small cities in Westchester, Long Island, and Connecticut. The observations are done using ECC 2Z ozonesondes and Vaisala 80-15 radiosondes normally used for ozone profiles in the troposphere and stratosphere. The sensors were placed forward on the boat, to avoid ozone produced by the boat's own engine. Several straight traverses were made between the north and south shores. These were extended into bays and harbors where it was possible without much bending of the trajectory, in order to lengthen the runs and carry them close to shore. These runs proceeded (somewhat diagonally, zig-zagging) from west to east, followed by a straight 30 mile direct radial transit approaching New York City southwestward. The data has been examined to look for aligned peaks on the transverse runs at the various radial distances from New York City, which would indicate the existence of ozone plumes transported northeastward from the city. Concentration variation in the radial direction was also examined. The study is expected to be extended to eastern Long Island Sound and the New York bight, south of Long Island
