因此,实验在欧洲、日本两个区域,对2016年的OCO-2、MODIS以及TCCON数据进行分析,以MODIS云层数据为云场景判定真值,通过逐步调整阈值组的方式,使OCO-2卫星数据总体通过率接近当地MODIS云层覆盖率的月均值,并据此分析最优阈值组的季度分布特征。数据表明,更严格的阈值选择提升了筛选结果与MODIS云层数据的匹配度,降低了与地...
A set of 164 atmospheric spectra from the Total Carbon Column Observing Network (TCCON) is used to compare three models, both previous and current versions of absorption coefficient tables (largely derived from recent multispectrum fitting analyses targeted specifically at these bands) as well as a...

with separation for soundings over land and water surfaces suggests the positive model biases in the high latitude regions arise mainly over the ocean surface. Similar plots cannot be made using data from the TCCON or NOAA network sites without significant interpolation in space and time due to th...

然后,采用HASM对OCO-2在2014年9月至2015年8月的各个月观测数据进行空间插值,获取空间分辨率为0.5°×0.5°的各个月均值XCO的空间分布,同时基于地基观测TCCON( Total Carbon Column Observing Network)站的XCO数据对HASM模拟结果进行交叉验证.验证结果表明,HASM模拟的XCO与TCCON站对应观测数据相比,其平均绝对值误差...
Although there are some TCCON sites located in urban areas (http://www.tccon.caltech.edu/site-locations/index.html), its effectiveness at city scale has not been fully evaluated. Because the soundings filtered out by the quality flags in the L1 product have no corresponding XCO2 values, we...
