Data on pollen is very valuable for many scientific questions relating to climate change, ecology and allergology. This data is analysed according to European standards by analysts at the Medical University of Vienna. At the Biologische Station Neusiedler See, a so-called pollen trap is used, which is positioned on the roof of the station and is maintained on a weekly basis. Air is sucked in and pollen particles adhere to a rotating adhesive film, allowing not only the detection of certain pollens, but also their temporal classification. This makes this method suitable for determining the pollen count and pollen forecasting.

Sudurnes Science and Learning Center focuses on bird studies, marine invertebrates, and seashore ecology. The Center cooperates with the Icelandic Marine Research Institute utilizing automated analyses of zooplankton (ZooImage) for taxonomic purposes. Other studies are mainly on aquaculture animals such as the European lobster, arctic char, and cod, where the Center carries out its own projects and/or participates in service programmes using the facilities at the Center. The main focus of The University of Iceland´s Research Centre in Sudurnes is on research and teaching in marine biology and ecotoxicology, emphasizing on postgraduate students. The Southwest Iceland Nature Research Centre collects and stores information and data regarding the nature in the southwest region of Iceland. The main focus has been on ecological research, mainly on bird ecology and benthic invertebrates. The Nature Research Centre takes part in monitoring breeding success in seabirds in Iceland as well as monitoring migratory waders that go through the Sudurnes region. Climatic data are available for the area at The Icelandic Meteorological Office since 1953.

Drained peatland, peat cutting stopped in 1979 but drainage ditches remain open. In the area of the tower footprint the peat body was not cut but is degraded due to oxygenation. Water levels draw down to as much as -60 to -70 cm in the end of summer and ca. -20 to -10 cm in winter. The site will be rewetted in the coming year

CEN Radisson Ecological Research Station (Station de recherche ecologique de Radisson). The station is the property of the Radisson municipality. It is run and operated by the following three member institutions of the Centre d'études Nordiques (CEN: Centre for Northern Studies): Université Laval, Université du Québec; Rimouski and Centre Eau, Terre et Environement of the Institut national de la recherche scientifique. The station has a long-term lease with the municipality. The CEN secretariat based at Université Laval oversees the management of the station. This station is part of the CEN Network, more precisely the Qaujisarvik Network of stations, and is the most southerly station of the network at 53°N. The vast expanse of the Québec territory, adjacent to James Bay, is administered by the Société d'énergie de la Baie James which is a subsidiary of Hydro Québec. Hydro Québec is responsible for emergency services and requires an annual logistical and security plan for all visitors.

The Czech Arctic Research Station of Josef Svoboda is situated in the High Arctic. The mean annual temperature is -6 °C, and the mean annual precipitation is 150-200 mm. Petuniabukta, where the field camp is located, is in the central part of the Svalbard archipelago, which is more continental and drier than the western part. There is a steep elevation gradient in the area (the highest mountains reach 1000 m a.s.l.). Various habitats can be accessed within walking distance in the study area, i.e. sandy beaches, waterlogged tundra, seepages, dry tundra, bird cliffs, lakes, snow-melt and glacial streams, glaciers, etc. Rich wildlife, incl. gulls, kittiwakes, terns, barnacle geese, eiders, reindeer, arctic foxes, and polar bears are present as well. Research mainly focuses on biodiversity and ecosystem dynamics. Relatively long research records on plant ecology, phycology, parasitology, and bioclimatology exist. Today, studies on geomorphology and hydrology are developing in the area. Regular meteorological measurements were established in 2007.

The site Heraklion Kornarou (ICOS code GR-HeK) is located in the city center of Heraklion, on the island of Crete, Greece, and is therefore classified as an urban site, mainly compact low rise LCZ3 in the Local Climate Zone (LCZ) scheme. The business areas and Heraklion's main thoroughfares, which are used for both commercial activity and commuter traffic, are concentrated in the northern part of HECKOR. The southern part is distinguished by residential districts with high building density and sparse, small scale vegetation areas, as well as by roadways with low traffic loads. Additionally, in an approximately 400m distance away but also inside the flux footprint, there is another notable feature of Heraklion's urban landscape, the Venetian walls (16th century). Commercial activity is a major contributor to the yearly carbon dioxide fluxes, especially during morning rush hours on weekdays and at lower levels at night and on weekends.
