Monitoring and Comparative Analysis of NO<sub>2</sub> and HCHO in Shanghai Using Dual-Azimuth Scanning MAX-DOAS and TROPOMI

This study employed dual-azimuth scanning MAX-DOAS to monitor vertical column densities of NO<sub>2</sub> and HCHO in Shanghai during the summer and winter of 2023, and compared the results with Sentinel-5P TROPOMI data. Dual-azimuth scanning revealed a generally consistent trend in gas...
