Implication

Observational study reveals a daily ozone decay rate driven primarily by ultraviolet photolysis in the marine boundary layer, highlighting major photochemical sinks over remote oceans.

Key Points

Quantify the rate and driving chemical mechanisms of diurnal ozone loss within the subtropical marine boundary layer.
Measured boundary layer ozone decay during a Lagrangian field experiment over the eastern Atlantic under partly cloudy conditions.
Modeled net ozone budgets by evaluating ultraviolet photolysis, hydroperoxyl radical interactions, surface deposition, and hydrocarbon photooxidation.
Observed a diurnally averaged ozone decay rate of approximately 0.11 day⁻¹ in the marine boundary layer.
Determined that photolysis by ultraviolet radiation serves as the primary driver of ozone loss, complemented by significant secondary sinks and counteracting photochemical production.
