Accordingly, this study aimed to investigate the relationship between temperature and air pollutants in Tehran, Iran, in order to determine whether warming is associated with an increase in air pollutants.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:115%"><span style="unicode-bidi:embed"><span calibri="" style="font-family:"><b><i><span style="font-size:10.0pt"><span style="line-height:115%"><span new="" roman="" style="font-family:" times="">Materials and Methods</span></span></span></i></b><span style="font-size:10.0pt"><span style="line-height:115%"><span new="" roman="" style="font-family:" times="">: During 2015-2019, Iran Air Quality Monitoring Station (AQMS) and the Landsat 8 satellite were employed to retrieve data on pollutants such as PM, CO, O₃, NO₂, SO₂, and air quality index (AQI), as well as climate-related metrics including ambient temperature and land surface temperature (LST). Pearson correlation coefficient and linear regression model were used to analyze the data.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:115%"><span style="unicode-bidi:embed"><span calibri="" style="font-family:"><b><i><span style="font-size:10.0pt"><span style="line-height:115%"><span new="" roman="" style="font-family:" times="">Results</span></span></span></i></b><span style="font-size:10.0pt"><span style="line-height:115%"><span new="" roman="" style="font-family:" times="">: A positive correlation was found between temperature variables and PM₁₀ (&rho; = 0.29, p = 0.001) and O₃ (&rho;= 0.55, p = 0.001) pollutants.
