Sažetak

To investigate the role of trees in the carbon cycle and point out the importance of preserving the alley, a student research project was designed, and a monitoring system was set up for Marmont Alley in Karlovac. The GLOBE program and the IT group included students who participated in the research project. In the beginning, the height and locations of all trees were measured using the GLOBE Observer application, and their circumference was measured. For each tree, the following were calculated: age, breast diameter, fresh and dry biomass, mass of stored carbon, and mass of absorbed CO2. The calculations were made using Python programming. It was confirmed that the amount of absorbed CO2 increases exponentially with the tree's age, which is why it is important to preserve old trees. Atmospheric factors were measured daily at the school meteorological station (100 m from the alley) and compared with the measured values of the Arduino system weather station with a sensor for measuring air quality determined by the total amount of gases in the atmosphere of Marmont Alley. The results indicated higher gas concentrations were recorded on days with increased air humidity and precipitation. A greater amount of gases was also measured in the late autumn when the trees had shed all their leaves. With this project, the students successfully integrated their biology, chemistry and computer science knowledge in interpreting ecological parameters.
