The WegenerNet climate station network Feldbach region is a pioneering weather and climate observation experiment at very high resolution located in Eastern Styria near the city of Feldbach in Southeast Austria, a region characteristic for experiencing a rich variety of weather and climate patterns. The network comprises 156 meteorological stations measuring temperature, precipitation, and other parameters, in a tightly spaced grid within an area of 23 km x 18 km centered near the city of Feldbach (46.93°N, 15.90°E). With its stations every about two square-km (area of about 300 square-km in total), and each station with 5-min time sampling, the network provides regular measurements since January 2007. As of 2010 a complementary meteorological-hydrological network of several stations was added in the mountainous upper Styrian region of National Park Gesaeuse as contribution to the LTER site Johnsbachtal (the "sister site" LTER_EU_AT_029_001 of this site LTER_EU_AT_029_002, both affiliated with the LTSER Platform Eisenwurzen). As part of the Johnsbachtal site, the WegenerNet Johnsbachtal consists of fourteen mountain-proof stations within a region-scale of about 10 km, ranging from valley altitudes below 700 m to mountain tops higher than 2100 m. The WegenerNet at both sites together provides strong value for both alpine foreland and mountain region studies.

The Oueme mesoscale site (Benin) is part of the AMMA-CATCH observation network. Its characteristics are as follows a 14000 km² basin in sudanian climate on a crystaline basement. The studies focus on the hydrological cycle, the water budget and the hydrological processes.

The Gourma mesoscale site (Mali) is part of the AMMA-CATCH observation network. Its characteristics are as follows :a 30000 km² endoreic area in semi arid climate. The studies are dedicated to vegetation monitoring in a pastoral environment.

The meteorological sensors are located on the roof of the main building of the Biological Station (N 47,7691; E 16,7662; Position (elevation): 122 msl) in the close vicinity of Lake Neusiedl. The parameters that are on-line recoded every 15 minutes are as follows: Air humidity (%RH), Global radiation (W/m²), Air temperature (°C), Wind speed ([Average] (km/h), Wind direction (°), Rain yearly (mm), Precipitation (mm); time resolution: 15 minutes. There are also two traditional weather stations at the station and on the jetty, which are maintained by the Hydrolographic Service Burgenland and enable parameters such as temperature, humidity, precipitation and water level to be recorded. In addition to the Adcon weather station on the roof of the station, there are currently 3 other stations in operation in Seewinkel. These positions are: • Unterer Stinkersee (N 47,8018; E 16,7842) • Neudegg (N 47,7029; E 16,8098) • Östliche Fuchslochlacke (N 47,7907; E 16,8624)

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.

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).

Pianosa Island (Long. 10° 04' 44” E and Lat. 42° 35' 07” N) is the fifth, by extension, of the seven islands of the Tuscan Archipelago National Park with a total area of 10.2 km2 and a coastal perimeter of approximately 20 km. The island is almost completely flat, with some small undulations. The highest elevation is 29 m above sea level (a.s.l.), while the average is about 18 m a.s.l. The climate of Pianosa is influenced by its flat morphology that prevents the condensation of moist air, resulting in a mean annual rainfall considerably lower than on the other islands of the Tuscan Archipelago; furthermore, due to the high permeability of the soils, the rain is quickly drained. On the basis of an historical meteorological dataset (1951-2009), mean air temperature is 15.8 °C and mean annual rainfall is 497 mm, ranging between a minimum of 176 mm (1999) and a maximum of 716.2 mm (1984). A clear seasonal precipitation pattern shows a maximum from October to December followed by a decrease with a minimum value in July. The first historical record of Pianosa island dates back to the Roman age, when the Emperor Ottaviano, in the 6-7 A.C., forced the grandson Agrippa Postumo to live on Pianosa island. Following the decadence of the Roman Empire, during the periods of Barbarians’ invasions, the island was abandoned. The name of Pianosa island newly appeared in some documents of the Repubbliche Marinare of Pisa and Genova (XII and XIII century) that reported the remarkable strategic position of the island. The 27th August 1802, Napoleone Bonaparte established that the islands of Elba, Capraia, Pianosa, Palmaiola and Montecristo were united to the territory of the French Republic. Bonaparte visited Pianosa twice and found it the most interesting of the other islands, appreciating its richness of vegetation and animals. In 1858 Pianosa became an Agriculture Penal Colony, where the prisoners were forced to work in the fields. During the ’70s the jail of Pianosa became a maximum security penitentiary. Only in the ’80s, representatives of the Government and members of the civil society started to propose to close the prison and to return Pianosa to the competent civil authority. In view of this, the number of the prisoners was drastically reduced and, consequently, several agriculture activities progressively stopped. In the 1997 the territory of Pianosa was formally included in the National Park of the Tuscan Archipelago and since than it is a site for natural conservation. In 1998 the penitentiary was completely dismissed

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.
