During the measurment of atmospheric environment with differential optical absorption spectroscopy, stray light of the sun will be added to the measurment spectrum and the Fraunhofer structure in the solar radiation could affect the measurement of NO, CH2O, HONO etc. But if it is treated as a k ind of `component' of atmosphere and retrieved with other atmospheric components together, its ef fect on the measurement could be restricted to a minimum.
