A new measurement of CO sub(2) eddy flux in the nearshore atmospheric surface layer

Abstract

Fluxes of CO sub(2) in the atmospheric surface layer have been measured at a shoreline site by the eddy correlation method using a new CO sub(2) sensor with greater sensitivity than the ones used in earlier studies. In this experiment, preliminary to more extensive measurements at an offshore site, 13 upward and downward fluxes were observed to respond to differences in pCO sub(2) between water and air. As in an earlier study, a negative correlation of CO sub(2) flux was found with hourly change in wind speed.
