BELLS is a low-frequency ground-based lightning network. The lightning sensors and central processor are based on Vaisala technology. Only lightning records that fulfill certain quality criteria, e.g., length of the semi-major axis, minimum number of sensors participating, are included.
Seasonal physiological and carbon‑related measurements of suspension feeders (Mytilus edulis and Balanus crenatus) from laboratory experiments in the Belgian marine environment
UNDER EMBARGO - This dataset contains seasonal physiological measurements from controlled laboratory experiments on two dominant suspension-feeding species expected to colonise floating offshore structures: the blue mussel (Mytilus edulis; AphiaID 140480) and the wrinkled barnacle (Balanus crenatus; AphiaID 106215). The measured parameters include clearance rates, respiration rates, faecal pellet production rates, and faecal pellet sinking velocities. Mussels were collected from an aquaculture longline at the Westdiep SeaFarm, while barnacles were manually retrieved from the intertidal beachhead at Raversijde (Oostende, Belgium). All experiments were conducted using natural seawater collected from offshore sites in the Belgian part of the North Sea. Measurements were repeated across multiple seasons to capture temporal variability in physiological performance. The dataset was produced within the SWiM and EcoMPV projects and is suitable for reuse in ecosystem and biogeochemical modelling, including simulations of phytoplankton dynamics associated with large-scale offshore marine photovoltaic (MPV) developments.
Greater North Sea, incl. the Kattegat and the English Channel
Physiological measurements were obtained from controlled laboratory incubations following standardised protocols. After an acclimation period, faecal pellets were collected using a vacuum-based siphoning system and subsequently used to determine sinking velocity in still-water columns by timing their descent over fixed distances. Pellet lengths were measured from microscope images analysed in ImageJ. Respiration rates were derived from changes in dissolved oxygen concentration, which were continuously monitored using calibrated Firesting optical oxygen sensors placed in stirred incubation chambers. Clearance rates were calculated from changes in particle concentration measured with a Coulter counter, and faecal pellet production was quantified from the dry mass and carbon content of pellets collected over known time intervals. All physiological rates were standardised to organism dry weight and carbon content, determined after drying soft tissues. Quality control procedures included calibration of sensors prior to measurements, the use of replicates and procedural controls, verification of calculation procedures, and the dataset underwent standard quality checks before harmonisation and archiving.
Networks of automatic lidar-ceilometer systems
The ceilometer CL51 employs a pulsed diode laser LIDAR technology, where short, powerful laser pulses are sent out in a vertical or near-vertical direction. The reflection of light (backscatter) caused by clouds, precipitation or other obscuration is analysed and used to determine the cloud base height, the cloud layer height and the amount of clouds (in octas) in different layers.
The cloud base height, the cloud layer height and the amount of clouds in different layers are computed by the Vaisala CL51 algorithm based on raw backscatter data (time resolution: 6 s and vertical resolution: 10 m). The sky condition algorithm is calculated every five minutes based on data collected during the last 30 minutes. The last 10 minutes are double-weighted to make the algorithm more responsive to variations in cloudiness. The algorithm uses cloud base height and timing information to find cloud base height close each other. These cloud base height are combined into clusters and a height value is calculated for each cluster. This height gives the base height of a cloud layer represented by the cluster. The algorithm reports layers by combining clusters whose heights are close to each other and then selecting clusters that cover the greatest amount of sky.

Govroam access points localization (WMS)
Govroam is a " wifi roaming " solution. This service offers to the users a simple and secure access to the wireless network of their institution, but also to networks of other participating institutions. A user from an organization that participates in govroam will be able to connect to any wireless access point broadcasting govroam. The data provided here makes it possible to locate these access points.
The map shows the location of Wi-Fi access points that broadcast govroam. This list is established on the basis of the information provided by the administrators of these access points (address of the building, local, ...). It is subject to change depending on the installation / uninstallation of new access points.

Total number of private households - Wallonia
The number of private households according to official statistics, per administrative unit (region, province, district and municipality) for Wallonia.
Definitions: In general, a household, in the statistical sense of the term, refers to all the occupants of the same dwelling, without these persons necessarily being linked by family ties (in the case of cohabitation, for example). A household may consist of only one person. Statistics: Household information is extracted by Statbel from two separate data sets. The first dataset contains the reference persons of the households. The second dataset contains the relationships of the household members to the reference person. From this dataset, Statbel also retrieves information on whether the household is a private or collective household. The datasets presented here are for private households only.
