In the stratosphere, ozone molecules play an important role absorbing ultraviolet radiation from the Sun and shielding Earth from dangerous rays. But in the troposphere, near ground-level, ozone molecules are both air pollutants, threatening the health of living things, and greenhouse gases, trapping heat and contributing to climate change. With our research, we sought to compare select weather parameters with surface ozone to determine which impact ozone levels. This would better allow researchers and scientists to prevent future increases in ozone levels. This led us to our research question, to what extent do select weather parameters impact local surface ozone levels? To successfully complete our research, we took daily measurements at our school’s soccer field using the PASCO wireless weather station and the Pocket Lab weather device. It was found that ozone correlated with pressure, relative humidity, and temperature. However, there was no real correlation between light intensity and surface ozone levels.

The team learned a lot about tropospheric versus stratospheric ozone and performed a well conceived investigation. Be careful about cause and effect with correlations. When you concluded that “the more ozone the more heat is retained,” I suspect what you are really seeing is greater surface ozone generation on hot days. I also suspect that the calculation of a Pearson correlation would indicate a moderate negative correlation between light intensity and ozone in your October plot. Additional data collection will help. I enjoyed your poster and was impressed with your attention to detail.
