Abstract：Photolysisrates（ J. -values） constitute a critical input for simulating ozone photochemical processes within observation-based models （OBMs），and the applicability of their calculation methods under different weather conditions directly affectsboth J. -valueestimationand ozone simulationresults.To addressthelackof systematic evaluation of the performance of the solar-zenith-angle method，the Hybrid method，and the TUV radiative transfer model under varying meteorological conditions，this study utilizes representative multi-day observational data from a monitoring site in northern China to assess the applicability of these three J. -value

calculation approachesacross different weatherregimes.Furthermore，oZone simulations driven by each method are compared within the FOAMmodeling framework. The J. -value simulations indicate that underrainy conditions，the TUVapproach improves accuracyby approximately 70% relative to the other two methods， whereasunderclear-skyconditions，the solar-zenith-anglemethodandtheTUVmodelyieldcomparable performance and are both suitable for application.The ozone simulations further show that under rainfall with stablewind fields，theTUVmethod performs best，with the index ofagreement （IOA）increasing bymore than 60% .Underclear and cloudy conditions，the solar-zenith-angle method is recommended for practical use. When external pollutant transport is present，OBM-based ozone simulations should not rely solely on the choice of photolysis ratecalculation method but must alsoaccount foractual wind speed，wind direction，and associated transport processes.Overall，theresults demonstrate that photolysis ratecalculation methods do have applicability issues for J. -value and ozone simulation under different weather conditions. Therefore，when performing J. -value and ozone simulations，a suitable photolysis rate calculation method should be selected for different weather conditions.
