China has become the world’s largest emitter of NO〈sub〉〈i〉x〈/i〉〈/sub〉, which mainly comes from vehicle exhaust, power plants, etc. However, there are no official ground-based measurements before 2013, so satellites have been widely used to monitor and analyze NO〈sub〉〈i〉x〈/i〉〈/sub〉 pollution here. Aerosol is the key factor influencing the accuracy of the satellite NO〈sub〉〈i〉x〈/i〉〈/sub〉 product. Our study provides a more accurate way to account for aerosol's influence compared to current widely used products.
