Global Soil-Biogenic NOx Emissions

This data set consists of gridded monthly mean global NOx biogenic emissions from soils at a 1 x 1 decimal degrees spatial resolution, averaged over the 1985-1995 ten years period. A global temperature and precipitation dependent empirical model of soil-biogenic NOx emissions was constructed using 6-hour general circulation model forcing. New features of this model included synoptic-scale modeling of 'pulsing' (the emissions burst following the wetting of a dry soil), a biome dependent scheme to estimate canopy recapture of NOx, and an explicit linear dependence of emission on N fertilizer rate for agricultural soils. This data set is part of the ECCAD GEIAv1 database. Source: Yienger, J.J., and H. Levy, II. 1995. Global inventory of soil-biogenic NOx emissions. J. Geophys. Res., 100: 11447-11464.

本数据集包含空间分辨率为1×1十进制度的网格化逐月全球土壤生物源氮氧化物（NOx）排放均值，统计时段为1985年至1995年共十年的平均结果。本研究依托6小时步长的大气环流模式强迫场，构建了依赖全球温度与降水的土壤生物源NOx排放经验模型。该模型的新增特性包括：对"脉冲效应"（即干土壤湿润后出现的排放爆发）开展天气尺度模拟、采用依赖生物群系的方案估算冠层对NOx的再捕获能力，以及明确农业土壤的排放强度与氮肥施用量呈线性相关关系。本数据集隶属于ECCAD GEIAv1数据库，来源文献为：Yienger, J.J. 与 H.
