Abstract

CO₂ anthropogenic emissions are estimated for St. Petersburg and Moscow megacities based on OCO-2 satellite CO₂ measurements. The CO₂ emission rates for St. Petersburg amount to 80 and 74 t/km² per day on March 1, 2016, and May 12, 2018, respectively. The CO₂ emission rate for Moscow is estimated as 123, 179, and 186 t/km² per day for August 25, 2018, June 22, 2018, and March 26, 2017, respectively. The comparison of our results with the estimates for other megacities has shown the emission estimates for St. Petersburg to be close to those for Los Angeles and Berlin, and estimates for Moscow to be close to those for London. The estimation errors are mainly caused by the anthropogenic contribution, which varies from 30 to ~90%.

基于OCO-2卫星测量的莫斯科和圣彼得堡人为CO 2排放量估算

摘要

根据OCO-2卫星的CO ₂测量值，估计圣彼得堡和莫斯科特大城市的CO ₂人为排放量。2016年3月1日和2018年5月12日，圣彼得堡的CO ₂排放量分别为每天80 t / km ²和74 t / km ²。莫斯科的CO ₂排放率估计为123、179和186 t / km ²分别为2018年8月25日，2018年6月22日和2017年3月26日。将我们的结果与其他特大城市的估算值进行比较，结果表明，圣彼得堡的排放量估算值接近洛杉矶和柏林的排放量，莫斯科的估算值也接近伦敦的排放量。估计误差主要是由人为贡献引起的，从30％到〜90％不等。
