WebIn the present study, we investigate the effects of signal to noise (SNR), slit function (FWHM), and aerosol optical depth (AOD) on the accuracy of formaldehyde (HCHO) vertical column density (HCHOVCD) using the ground-based direct-sun synthetic radiance based on differential optical absorption spectroscopy (DOAS). We found that the effect of SNR on … Web26 de fev. de 2024 · Among these strategies, photocatalytic oxidation is by far the most promising method owing to its high HCHO removal efficiency, energy-saving power, and mild reaction conditions (Yu et al. 2013).
