Data for "Effect of elevated tropospheric ozone on soil carbon and nitrogen: A meta-analysis"

These data were extracted from 41 peer-reviewed studies to quantify the impact of O₃ 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 (NH₄⁺), nitrate N (NO₃^-), 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 [O₃] across all studies was 27.6±18.7 nL/L.<br>

本数据集提取自41篇同行评议研究，旨在量化臭氧（O₃）对10项与土壤碳、氮相关变量的影响，具体包括总碳（TC，涵盖土壤有机碳）、总氮（TN）、可溶性有机碳（DOC）、氨态氮（NH₄⁺）、硝态氮（NO₃⁻）、微生物生物量碳（MBC）与微生物生物量氮（MBN）、硝化速率（NTF）、反硝化速率（DNF）以及碳氮比。数据集源自分布于北纬25°28′至60°49′、西经88°14′至东经123°24′范围内的17组实验。实验区域的年平均气温（MAT）区间为1.1℃至26.6℃，年平均降水量（MAP）区间为460毫米至1280毫米。所有研究中臭氧浓度的平均增幅为27.6±18.7纳升每升（nL/L）。
