摘要:

全球大气二氧化碳浓度2°x2.5°栅格模拟数据集(1992-2020)是以2002-2012年全球对流层CO2浓度卫星遥感产品(AIRS,AIRx3C2M 005)为基础,对改进的CO2浓度正弦估算模型进行逐像元参数计算;在此基础上,利用基于像元的模型进行CO2浓度模拟回溯至1992,预测至2020。最后,利用站点观测数据对产品精度进行验证与分析。该数据集覆盖范围为60°S – 88°N,180°W-180°E,空间分辨率为2° x 2.5°。数据集由两部分组成:(1)1992-2020年全球逐月CO2浓度均值数据集;(2)1992-2020年全球逐年CO2浓度均值数据集。数据集以.nc格式存储,由58个数据文件组成,数据量为31.5 MB(压缩为1个文件,23.9 MB)。
