Parameterization of Zelkova serrata stomatal conductance model to estimate stomatal ozone uptake in Japan
چکیده انگلیسی

To parameterize stomatal conductance or ozone uptake modeling in the Eastern Asian tree species Zelkova serrata, measurements of stomatal conductance were carried out in several Japanese sites across the growing season. The new parameterization improved the stomatal conductance model performance relative to a previously proposed model. The results were used to compare the spatial distribution of AOT40 and Z. serrata stomatal ozone uptake in Japan. Including a soil moisture function improved the model in the short periods with low precipitation. In addition, elevated vapor pressure deficit and soil moisture deficit due to high temperature, and high ozone exposure induced stomatal closure. The consequent decoupling of stomatal ozone uptake from high ozone exposure suggests caution in using AOT40 as a standard for Z. serrata protection in Japan.


► We parameterized stomatal conductance of Zelkova serrata for ozone uptake modeling.
► The new parameterization improved the performance of stomatal conductance model.
► The result was used to compare the spatial distribution of AOT40 and stomatal ozone uptake in Japan.
► Stomatal ozone uptake of Z. serrata was limited by vapor pressure deficit, soil moisture deficit and ozone.
► Our result suggests caution in using AOT40 as a standard for Z. serrata protection in Japan.
