In addition to its network of meteorological stations, the Slovenian Environmental Agency also operates automatic hydrological and ecological stations. While these two types of stations are primarily designed to monitor other environmental variables, some are also equipped with air temperature sensors.
For four selected locations, I compared temperature measurements from paired meteorological and ecological stations to analyze their differences and identify the conditions under which the largest discrepancies occur. The analysis revealed that, in most cases, the ecological stations tend to report slightly higher air temperatures than the corresponding meteorological stations.
Further investigation indicated that these discrepancies are closely related to wind speed and global solar radiation. The most pronounced differences were observed during periods of low wind combined with strong solar radiation, suggesting that localized heating effects near the ecological stations may influence the recorded values. The highest differences in measured air temperature reach up to 3 °C.
