This research assessed the disparity in anion generation according to the vertical structure of a Zelkova Serrata tree for the purpose of creating a pleasant and green city environment. Measurements for the study were conducted between July and August of 2014 in Chung-ju in the central region of the Republic of Korea. The average anion generation of vertical structure trees during active photosynthesis periods was: L Section (839.0 ea/cm<sup>3</sup>) > M Section (664.6 ea/cm<sup>3</sup>) > U Section (472.0 ea/cm<sup>3</sup>). According to DMRT analysis, significant difference was found in the average between the L, or M Locations and the U Locations. During dormant photosynthesis periods, records showed that the anion production at the M Location (1,212.5 ea/cm<sup>3</sup>) > L Location (1,050.4 ea/cm<sup>3</sup>) > H Location (844.1 ea/cm<sup>3</sup>), According to DMRT analysis, the difference within each location was significant for α=0.05. In a comprehensive analysis of the weather factors in each vertical structure, anion generation during active photosynthesis periods showed a positive correlation with solar radiation and a negative correlation with wind speed. Dormant photosynthesis periods showed negative correlations with both solar radiation and temperature, and positive correlations with relative humidity and wind speed. Predictions from a multicenter retrospective study showed that during active photosynthesis periods, Y<sub>1</sub> = 282.443X<sub>1</sub> + 512.07, and Y<sub>2</sub> = 314.337X<sub>1</sub> + 16.913X<sub>2</sub>, while during dormant photosynthesis periods, Y<sub>1</sub>=391.009X<sub>1</sub> + 840.043, and Y<sub>2</sub>=351.412X<sub>1</sub> + 32.765X<sub>2</sub>.
