Reply to comments on ”Simulating ozone dry deposition at a boreal forest with a multi-layer canopy deposition model”
“In SOSAA, the horizontal wind velocity (u and v), temperature (T ), specific humidity (qv), turbulent kinetic energy (TKE) and the specific dissipation of TKE (ω) are computed every time step (10 s) by prognostic equations. In order to represent the local to synoptic scale effects, u, v, T and qv near and within the canopy are nudged to local measurement data at SMEAR II station with a nudging...

A multi-layer ozone (O3) dry deposition model has been implemented into SOSAA (a model to Simulate the concen-trations of Organic vapours, Sulphuric Acid and Aerosols) to improve the representation of O3 concentration and flux withinand above the forest canopy in the planetary boundary layer. We aim to predict the O3 uptake by a boreal forest canopy undervarying environmental condit...

1. Comments: (1) Authors state that they have implemented a multi-layer dry deposition model into SOSAA, which is a 1D chemical transport model. SOSAA is described in Section 2.3.1, which lists different modules and references but does not explain the model types or physical principles. The key elements of SOSAA relevant to the present study, especially turbulent mixing and the derivation of ed...
متن کاملSub-canopy deposition of ozone in a stand of cutleaf coneflower.
Although there has been a great deal of research on ozone, interest in exposure of native, herbaceous species is relatively recent and it is still not clear what role the pollutant has in their ecological fitness. The ozone exposure of a plant is usually expressed in terms of the concentration above the canopy or as a time-weighted index. However, to understand the physiological effects of ozon...
متن کاملForest thinning experiment confirms ozone deposition to forest canopy is dominated by reaction with biogenic VOCs
[1] Ecosystem ozone uptake can occur through stomatal and surface deposition and through gas phase chemical reactions. In a California pine forest, thinning dramatically enhanced both monoterpene emission and ozone uptake. These simultaneous enhancements provide strong evidence that ozone reactions with unmeasured biogenically emitted volatile organic compounds (BVOCs) dominate ozone uptake, an...
