最近，美国国防部气象卫星计划(DMSP)业务直线扫描系统(OLS)的稳定光产品和辐射定标产品已用于以高空间分辨率绘制全球化石燃料二氧化碳(CO2)排放图。然而，利用索米国家极轨伙伴(NPP)卫星上的可见光成像辐射计组件(VIIRS)传感器提供的新一代夜间光数据进行的研究很少，该传感器比传统的DMSP-OLS夜间光数据具有更高的空间分辨率和更宽的辐射探测范围。因此，这项研究首次评估了NPP-VIIRS数据在估计全球二氧化碳排放(不包括发电厂排放)空间分布方面的潜力。然后，通过分解模型，根据人口统计和三种不同类型的夜间灯光数据(NPP-VIIRS、DMSP-OLS的稳定光数据和辐射校准数据)得出三张全球辐射图，以进行比较分析。与北京、上海和广州的土地覆盖参考数据的对比结果表明，NPP-VIIRS数据的MAP排放面积与人工地表具有更高的空间一致性，并且显示出更合理的二氧化碳排放分布。此外，与DMSP-OLS数据的两张图相比，NPP-VIIRS数据的排放量图更接近火神清单，并与美国次行政单位层面的二氧化碳排放实际统计数据显示出更好的一致性。这项研究表明，NPP-VIIRS数据可以成为研究二氧化碳排放的空间分布以及多尺度上的社会经济指标的有力工具。
Recently, the stable light products and radiance calibrated products from Defense Meteorological Satellite Program’s (DMSP) Operational Linescan System (OLS) have been useful for mapping global fossil fuel carbon dioxide (CO2) emissions at fine spatial resolution. However, few studies on this subject were conducted with the new-generation nighttime light data from the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the Suomi National Polar-orbiting Partnership (NPP) Satellite, which has a higher spatial resolution and a wider radiometric detection range than the traditional DMSP-OLS nighttime light data. Therefore, this study performed the first evaluation of the potential of NPP-VIIRS data in estimating the spatial distributions of global CO2 emissions (excluding power plant emissions). Through a disaggregating model, three global emission maps were then derived from population counts and three different types of nighttime lights data (NPP-VIIRS, the stable light data and radiance calibrated data of DMSP-OLS) for a comparative analysis. The results compared with the reference data of land cover in Beijing, Shanghai and Guangzhou show that the emission areas of map from NPP-VIIRS data have higher spatial consistency of the artificial surfaces and exhibit a more reasonable distribution of CO2 emission than those of other two maps from DMSP-OLS data. Besides, in contrast to two maps from DMSP-OLS data, the emission map from NPP-VIIRS data is closer to the Vulcan inventory and exhibits a better agreement with the actual statistical data of CO2 emissions at the level of sub-administrative units of the United States. This study demonstrates that the NPP-VIIRS data can be a powerful tool for studying the spatial distributions of CO2 emissions, as well as the socioeconomic indicators at multiple scales.
