Xianghe HCHO MAX-DOAS MMF data with monthly CAMS model profiles as a priori

MAXDOAS vertical profile data of HCHO at XIANGHE (39.75° N, 116.96° E, CHINA) from BIRA.IASB instrument nr 007 and uv channel 002 for the year 2020. Data retrieval performed using the Optimal-Estimation-based Mexican Maxdoas Fit algorithm (MMF; Friedrich et al., 2019, https://doi.org/10.5194/amt-12-2545-2019) with a monthly a priori profile coming from the CAMS model.
