This study aims to examine the relationship between meteorological factors, specifically temperature, solar radiation, and ozone concentration levels. Levels of surface ozone were monitored (O) in Chonburi, Thailand (located at 3.2017° N, 101.2524° E), from January 2010 to December 2020. Thailand's coastal tropical environment provided a unique setting for the study. The study revealed a distinctive seasonal trend in ozone levels, with the highest concentrations occurring during the winter and the lowest in the rainy season, on average. The increase of O in the summer was primarily attributed to intense ground-level solar radiation and higher temperatures of around 30-35 °C, enhancing O concentrations ranging from 200 to 1400. During the winter, there is an increased elimination of the O concentration by higher levels of NO. The study also examined the relationship between ozone levels and various meteorological factors to identify which had the most significant impact on ozone formation. The analysis showed that the ozone concentration has a strong negative correlation with relative humidity but is positively correlated with solar radiation, temperature, and wind speed.
本研究旨在探讨气象因素之间的关系，特别是温度、太阳辐射和臭氧浓度水平。2010年1月至2020年12月期间，在泰国春武里（北纬3.2017°，东经101.2524°）监测了地表臭氧水平（O）。泰国沿海的热带环境为该研究提供了独特的背景。研究揭示了臭氧水平呈现出明显的季节性趋势，平均而言，冬季臭氧浓度最高，雨季最低。夏季O浓度的增加主要归因于强烈的地面太阳辐射以及约30 - 35°C的较高温度，使得O浓度在200至1400之间升高。在冬季，较高水平的NO增加了对O浓度的消除。该研究还考察了臭氧水平与各种气象因素之间的关系，以确定哪些因素对臭氧形成影响最为显著。分析表明，臭氧浓度与相对湿度呈强烈负相关，但与太阳辐射、温度和风速呈正相关。
