Components of gradient flux calculated OCS flux for June 14, 2011. (A) gOCS: OCS gradient (black; pptv⋅m⁻¹), confidence intervals of the OCS gradient (gray bars, which are barely visible). (B) gH₂O: H₂O gradient (dark blue; pptv⋅m⁻¹), confidence intervals of H₂O gradient (gray bars). (C) FH₂O: H₂O flux (blue; mmol⋅m⁻²⋅s⁻¹), 15% error on eddy covariance measurements (gray bars). (D) gFOCS: OCS gradient flux (pmol⋅m⁻²⋅s⁻¹), 2-h average (black), and 30-min gFOCS (gray points with SE as gray bars). (E) FCO₂: CO₂ flux (as NEE including storage contribution) (μmol⋅m⁻²⋅s⁻¹), 30-min FCO₂ (small light green points), 15% error on eddy covariance measurements (green bars), 2-h mean (dark green points).
