Abstract:Key physical and chemical factors in formation of O3 were studied with photochemical mechanism RADM2 and CBM-Z. Using the box model with various combinations of these factors, the look-up table was produced to depict the concentration variation of O3 and its precursors(VOC, NOx). The look-up table was applied in regional air quality model CALGRID to simulate tropospheric ozone over Pearl River Delta in January, April, July and October, 2006. It is found that employing look-up table scheme could significantly increase the computational efficiency, saving 45%~48% operation time. Meanwhile, the results coincided well with those calculated directly by photochemical mechanism. O3 and NOx were well simulated using look-up table based on RADM2 and CBM-Z, respectively.
