摘要：Long–path differential optical absorption spectroscopy is one of the best–suited monitoring techniques for the initialization and validation of photo chemical grid models. This technique has proven to be useful as well for tracking pollution episodes and for long-term monitoring of criteria and non-criteria air pollutants. DOAS is a highly specific, non-invasive technique particularly appropriate for the detection of very reactive species, such as fonmaldehyde, nitrous acid, nitrate and hydroxyl radicals. In addition, once a DOAS system is furnished with the appropriate reference spectra, it requires no further gas calibration in the field.
