Abstract


The effect of optical path length (OPL) and pressure variation on the ozone gas absorption cross section (OACS) is been reported. The current available line list on the spectralcalc online simulator tool was used to simulate the results obtained. Simulation results show that at 255.442 nm where the absorption of light is at its peak, the OACS maintained a value of  as the pressure was changed successively from 0.1 to 3.0 atm while the OPL is increased from 0.75 cm through 130 cm. However, at a higher wavelength of 296.73nm where light absorption is weakest in the UV, both OPL and pressure variation had no effect on the OACS as it maintained a constant value of . Therefore, OACS is independent on pressure and OPL.
