A total eclipse traversed from Oregon to South Carolina on 21 August 2017. The atmospheric response to the total eclipse was observed as a partial eclipse by the Oklahoma Mesonet at 120 automated weather stations across the state of Oklahoma. The observations were recorded by the Mesonet in 1-Minute intervals. The maximum and minimum temperature values were determined for each site at 1.5 m and 9 m. The maximum and minimum temperature was determined by finding the minimum temperature and establishing a maximum temperature that occurred before the minimum. A maximum temperature change was then calculated for each site. After plotting the calculated temperature on a map of Oklahoma, the gradient was found to be related to occlusion percentages. Additionally, the stability was quantified for each site and plotted on a map of Oklahoma. A stability value found to be related to occlusion percentages across the state as well.
