AZores Observation NETwork: AZONET
Operational (year-round For MBL Stations, Summertime For Pico Mountain)
The MBL stations are available for collaborative year-round measurements. The Pico Mountain station currently has limitations on space and power usage and is currently operational only during summer. However, it is being expanded and will be available for year-round collaborative measurements in the future.

Surface In-Situ Networks
A set of observation platforms for atmospheric composition and radiation measurements in the marine boundary layer and lower free troposphere of the central North Atlantic region, based in the Azores Islands (Portugal). Included are the Pico Mountain observatory on Pico Island and marine boundary layer observatories on Terceira Island.
