Niakhar is a complementary site of the AMMA-CATCH observation network, that has been set up to study the longitudinal gradient over West Africa in comlement to the mesoscale sites. It is located in central Senegal, under Sahelian climate in a rural area, 150 km from Dakar. The studies focus on meteo/vegetation interactions in a cultural complex. The AMMA-CATCH site is coupled with the "long-term Collaborative Observatory on agroforestry ecosystem services", managed by partners since 2018.

Concordia is a joint French-Italian research facility opened in 2005 on the Antarctic Plateau, Antarctica (-75.1, 123.33), managed together by PNRA (Italian National Antarctic Programme) and IPEV (Institut Polaire Francais Paul Emile Victor). It is built at 3,233 m above sea level on the third highest summit of Antarctica: Dome C.

The Jiaozhou Bay, covering an area of 390 km2 between 3538′ and 3618′ N and 12004′ and 12023′ E, surrounded by the Qingdao city. As a semi-enclosed, fan-shaped bay, the narrowest place at the channel connecting with the Yellow Sea, from the Tuan Island to the Xuejia Island, is only 3000 m wide. Its average depth is 6-7 m, with most part of the bayshallower than 5 m, and the tidal zone adds up to 125 km2. The tide of Jiaozhou Bay is regular semidiurnal type. The speed of the flood is greater than that of the ebb, and the duration of the flood is shorter than that of the ebb. There are many peninsulas and islands in the bay, so the circulation inside is complicated. After the residual current analysis, six circulation systems were observed in Jiaozhou Bay. Marine biodiversity and productivity is high in the bay. With the development of Qingao City, the population is increasing quickly around Jiaozhou Bay. Farms, factories, highways, ports, tourism etc. can all affect the environments of the bay. Most of the land-sourced input are from several rivers, such as the Dagu, Haibo, Licun and Nan Jiaolai rivers.

Meteorological and snow parameters are recorded hourly since 1961. These parameters are : - Air temperature and relative humidity of air - Incoming and outcoming short and long-wave radiations - Wind speed and direction - Precipitation - Snow depth, snow water equivalent - Settlements and snow temperatures of the different layers of the snowpack Weekly snowpack profiles are also carried out, including major stratigraphic properties of snow (temperature, density, liquid water content, snow type).

It is located in the region of the Grand Causses, south of the Massif Central. The karstic aquifer of Durzon represents a surface of 100 km² which feeds the spring of Durzon. This spring supplies the drinking water of the Aveyron part of Larzac. The observatory has a set of sites dedicated to gravimetric, inclinometric and hydro-geodesic observations, as well as a flow tower for evapotranspiration measurements.

Processing of time series of satellite and airborne images, with different spatial and spectral resolution, in order to derive water quality maps based on physically based algorithms parametrised with specific optical properties of lake Garda. Generation of spatial and temporal information of different water quality parameters of surface water column and coastal zone. Dedicated actives of calibration and validation of satellite images, algorithms and products.

The site is a cropland with a 4-year rotation. Fluxes of CO2 and water vapour are measured by an eddy covariance system. Research activities are carried out by the university of Liège (GxABT).

The Třeboň Wet Meadows is an LTER site of a 1 hectare area. It is a part of a wetland with the total area of 450 hectares situated in the inundation area of a large human-made reservoir (Rožmberk fishpond, 5 km2). The Wet Meadows are a predominantly herbaceous wetland with an up to several meters thick layer of organic sediment, which is superimposed on quaternary alluvial sands and clays. The vegetation cover is formed mainly by tall sedges (Carex acuta, C. vesicaria) and reed Canarygrass (Phalaris arundinacea). During the last 50 years, after cessation of mowing, a distinct stand structure of hummocks and hollows has developed. The hummocks are formed by tussocks of Carex acuta. On the site, wide water level fluctuations are recorded in some years. The relatively regular spring floods and irregular summer floods occur as a consequence of snow melting and summer rains in the catchment area, respectively. Extreme floods occurred in the summer of 2002 and both spring and summer of 2006, when the water level culminated at 2 m above the soil surface. The most frequently recorded position of the water level is at about −0.1 m. From 1977 to 2006, meteorological measurements were executed in a meteorological screen. Starting from 2006, the measurements have been executed with electronic sensors connected to data-loggers. Since that time, the site has been equipped for measuring carbon exchange and fluxes of CO2 and H2O (eddy covariance system, Licor). Since the spring of 2011, the site has been equipped for measuring methane and CO2 emissions from the sedges (automatic static flow chamber with a laser gas analyzer, LGR).The Wet Meadows are included in the integrated carbon observation system (ICOS) as a wetland ecosystem station.

The Sany Bay, covering an area of 120 km2 between 109.3333 and 109.5 E and 18.183 and 18.3 N, surrounded by the Sanya city. It is a typical tropical bay in China. Dongmao Island, Ximao Island and Luhuitou, located in the bay mouth, possess mostly coastal coral reefs. The Sanya River, located in the eastern part of the bay, has many kinds of tropical habitats including coral reefs, mangroves, rocky and sandy shores, mudflats, etc. The coral reefs and mangroves have special resource value and ecological benefits and are, therefore very important to the sustainable social and economical development in these tropical coastal areas. Coral reefs and mangrove areas have important relationships to the regulation and optimization of the tropical marine environments.

Landslides (translational and rotational slides, debris flows, rock avalanches, rock falls, etc.) rank among the most common natural hazards in Lower Austria. As these processes often inherit sporadic phases of activity, it is essential to generate specific long-term measurement series, enabling the analysis of surface and sub-surface dynamics in connection with potential triggering factors. Therefore, in 2014 the project “NoeSLIDE – Monitoring diverse types of landslides in Lower Austria” was initiated. Three subsites are summarized under the parent site "LTER NoeSLIDE".where various types of landslide processes, Hofermühle (complex earth slide - earth flow), Gresten (Salcher landslide) and Brandstatt are monitored with "classic" as well as novel approaches. This includes surface and subsurface monitoring systems. The main research aims comprise implementation of long-term monitoring systems (10+ years) for continuous observation of gravitational mass movements, testing of novel and innovative methods on multiple locations and data availability in a WebGIS application for simple online analyses for authorized users.
