The impact of urban trees on temperature regulation in the downtown area of Junín de los Andes, Argentina, in different seasons of the year was investigated. The research questions were: How much does surface temperature and air temperature change in the downtown area of the city of Junín de los Andes, in the different seasons of the year? How does the distribution of trees vary on the sidewalks in the city center and in San Martín Square? How does tree coverage influence: a) surface temperature and b) air temperature? How does cloud type and coverage influence surface and air temperature?
The GLOBE Program atmosphere and biosphere protocols were applied to collect data in 4 downtown streets and in San Martin square. Measurements included tree height and circumference, land cover, land surface temperature and air temperatures. The results reveal an uneven distribution of trees on the sidewalks and the Square stands out with the highest coverage. Significant temperature differences were detected between stations. The data revealed a significant correlation between tree cover and the decrease in land surface temperature in summer, demonstrating its impact on urban thermal regulation. The samplings were influenced by the ENSO phenomenon and low cloud cover in autumn, winter and summer
