Arzaga Meteorological Observatory

The Arzaga Meteorological Observatory has been in operation since November 2022 and is located approximately 122 metres above sea level in the Arzaga district of Milan, Italy. It consists of a weather station and four live cameras facing north-east and south-east.

The weather station monitors the urban climate, defined as “the local climate that differs from that of the surrounding rural areas as a result of urban development.” This means that air temperature, precipitation, atmospheric pollutant concentrations and wind speed often differ from those recorded in the surrounding areas.
Cities are characterised by densely built-up areas, which lead to higher air temperatures and the formation of an urban heat island. Buildings and roads absorb energy from solar radiation during the day and release it as heat during the night.
