Data for "Effect of elevated tropospheric ozone on soil carbon and nitrogen: A meta-analysis"
收藏资源简介：
These data were extracted from 41 peer-reviewed studies to quantify the impact of O<sub>3</sub> on ten variables associated with soil C and N, i.e., total C (TC, including soil organic C), total N (TN), dissolved organic C (DOC), ammonia N (NH<sub>4</sub><sup>+</sup>), nitrate N (NO<sub>3</sub><sup>-</sup>), microbial biomass C (MBC) and N (MBN), rates of nitrification (NTF) and denitrification (DNF), as well as C/N ratio. The data were acquired from 17 experiments performed at 25°28' N to 60°49' N latitude and 88°14' W to 123°24' E longitude. The mean annual temperature (MAT) ranged from 1.1 °C to 26.6 °C, and the mean annual precipitation (MAP) ranged from 460 mm to 1280 mm. The average increment in [O<sub>3</sub>] across all studies was 27.6±18.7 nL/L.<br>
