【摘要】 针对地面监测点位过少,不能满足大区域范围土壤酸沉降通量研究需求的现状,建立了基于OMI痕量气体遥感数据和地面观测数据的区域酸沉降通量估算方法,并对青岛市硫元素和氮元素沉降通量进行了估算。结果表明,新方法能够实现大区域范围土壤酸沉降通量的估算。与传统估算方法相比,新方法采用大气痕量气体遥感监测数据,是对酸沉降通量常规研究手段的有益补充。更多还原

【Abstract】 To solve the problem that the lack of ground monitoring data could not meet the spatial needs for the study of atmospheric acid deposition fluxes, a method for estimating regional acid deposition fluxes based on the OMI atmospheric satellite remote sensing data and the ground observation data was proposed. With the proposed method, the sulphur and nitrogen deposition fluxes of Qingdao City were estimated. The results showed that the acid deposition on soils on a regional scale could be evaluated with the proposed method. Compared to the traditional methods,the proposed method provided the study of atmospheric acid deposition with the supplementary basis and reference.更多还原
