The Cyprus Atmospheric Observatory station in Nicosia currently consists of two containers on the grounds of the Cyprus Institute at the Athalassa campus, in Aglantzia. The containers are stacked on top of each other, with sampling instruments located in the top container.

This station serves two purposes to CAO: First, it is a testing ground where instruments can be developed/tested/optimized/repaired. This is necessary when adapting instruments to new platforms, such as UAVs; when instruments are going to/coming back from campaigns; when instruments are not operating up to the high standards required for research work; or when performing comparison between multiple instruments measuring the same/similar variables. The second function of this station is to operate as an air quality station, with parameters such as CO, SO2, NOX, O3, PM2.5 and PM10 concentrations being monitored constantly (Thermo 4# C series and 1405-DF TEOM instruments).

The station will be relocated on the top floor of the Climate and Atmosphere Research Centre building once construction is finalised in 2022/23.
