Volatile organic compounds (VOCs), which participated in photochemical reactions, were main precursor of photochemical pollution, and also the critical pollutants that currently affected China’s urban air quality. The pollution situation of VOCs was complex and had many unknown factors, due to the lack of convenient and fast monitoring measurement. The technology of solar occultation flux based on FTIR(SOF-FTIR)was used to rapidly scan pollution areas for real-time monitoring, and it was found that vertical column density peak values of most VOCs was ranged from 10 ppm·m to 60 ppm·m, and local pollution was easily formed.
