The impacts of enhanced nitrogen (N) deposition on global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

Uptake of nitrogen forms by diploid and triploid white poplar depends on seasonal carbon use strategy and elevated summer ozone

Miaomiao Wang, Guolei Li, Zhaozhong Feng, Yong Liu, Yansen Xu & Mercedes Uscola
This dataset contains data from an experiment described in the paper: "Miaomiao Wang, Guolei Li, Zhaozhong Feng, Yong Liu, Yansen Xu, Mercedes Uscola. Uptake of nitrogen forms by diploid and triploid white poplar depends on seasonal carbon use strategy and elevated summer ozone. Journal of Experimental Botany, erab317, https://doi.org/10.1093/jxb/erab317". In the study, we investigated the mechanisms of N forms acquisition in response to developmental phase allowing us to analyze the plasticity in N forms preferences...

Application of turbulent diffusion term of aerosols in mesoscale model

Wenxing Jia
The presence of unfavorable meteorological conditions triggers pollution, and then further weakens turbulence, especially in the stable boundary layer (SBL), which is a frequent situation in heavy pollution episodes in China. The inapplicability of the classical Monin-Obukhov similarity theory (MOST) and the uncertainty of the planetary boundary layer height can lead to large deviation of turbulent diffusion in the SBL in numerical simulations. However, in current mesoscale models, no term has been used to accurately...
