AN PRELIMINARY APPROACH TO PHOTOCHEM-ICAL REACTION IN THE INTERNAL BOUNDARY LAYER

Taking Maoming Oil industrial area which is not far away from the South-China Sea as an example, the continued high level pollution of NOx and HC formed under the internal boundary layer and their effects on photochemical reaction in low-level atmosphere are studied. By way of photochemical reaction modelling and comparision with the monitoring results, some distribution features of photochemical oxidants such as O3 etc. are analyzed.
