Rado-Cluj is a ground-based fixed site located in the north-western part of Romania, in Cluj-Napoca at the Faculty of Environmental Science and Engineering (Lat.: 46.76833°N, Long.: 23.55139°E, elevation: 405 m). The site can be considered representative for the whole Transylvanian territory, and the Pannonian Basin, given the limited coverage of other similar sites in the area.

The main sources of local emissions are represented by heavy traffic and heating facilities during winter, with few emissions related to industrial facilities. Due to the temperate continental climate, the monthly average air temperature in Cluj-Napoca can vary greatly, ranging between −2.1 °C in January and 21.1 °C in July, with a mean annual air temperature of 10.3 °C. The wind direction in Cluj-Napoca is largely influenced by the local topography, being fairly consistent with the Someșul Mic
