Summer and winter mean relative humidity given in %. The relative humidity fields are available for the present target year 1975, which corresponds to the middle of the 30-year period 1961-1990.

Foreign real estate - Owners' profile corresponds to the dataset describing the profile of Belgian taxpayers (natural persons) holding real estate abroad. This dataset is composed of five classes. The first shows, at national level, by age and sex category, the number of individuals holding a real right that allows enjoyment over foreign property, the total number of foreign properties held by these individuals, and the number of properties by foreign country or territory. The number of properties takes into account the shares actually held. The second class presents this information at the level of the three regions. The following classes do the same for provinces, arrondissements and communes. The dataset is freely downloadable as zipped CSV files.

UNDER EMBARGO - This dataset contains the data on porewater nutrients, sediment granulometry, and pigment concentrations that were collected in the C-power offshore wind farm in spring, summer, and autumn of 2022 for the OUTFLOW project. Data were gathered at increasing distances from the scour protection layer (SPL) of a wind turbine, 7, 15, 25, and 75 m away from the edge. Cores were collected by divers, and a boxcore was used for samples 75 m away. From these cores, porewater nutrients were collected with rhizon samplers, and cores were slices in 0.5 to 2 cm slices, and each slice was analyzed for total organic carbon, total nitrogen, granulometry, and algal pigment concentrations.

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 Belgian seismic network of the Royal Observatory of Belgium (ROB), with about 45 permanent stations, is mainly dedicated to the monitoring and the scientific study of the seismic activity in Belgium. The ROB is also managing 3 stations in the Grand-Duchy of Luxemburg (in cooperation with the European Center for Geodynamics and Seismology). Earthquakes worldwide with magnitude greater than 4.5 – 5.0 are routinely recorded by the Belgian seismic network. The measurements on these recordings are sent to international seismological centers (EMSC and ISC) where data from stations worldwide are analyzed to furnish a global catalogue of earthquakes and phase arrival time models. We also provide real-time seismic signals from some Belgian stations to data exchange centers like ORFEUS (Observatories and Research Facilities for European Seismology) and IRIS (Incorporated Research Institutions for Seismology).To complement the seismic network, the Belgian accelerometric network was installed early in the 2000ies to furnish reliable data when strong ground motions saturate traditional seismometers. This network consists of 19 stations, is sensitive to accelerations of 1E-5 g (g is gravity at the Earth’s surface) and is an important tool for professionals in the field of earthquake engineering and engineering seismology (seismic hazard assessment). Currently, since 2014 the service is installing another network (“AcceleROB“) of 90 low-cost accelerometers. These sensors are calibrated to be sensitive to accelerations of 1E-3 g, which should be observed during any earthquake of local magnitude ML=3 or larger.

The Royal Decree of 20 March 2026 establishing the marine spatial plan for the period 2026 to 2034 in the Belgian marine areas defines 1 measuring pole: Measurement poles (Art. 25§2). It replaces the 2020 Marine Spatial Plan. Please refer to the Belgian official gazette ("Moniteur belgeBelgisch Staatsblad") for official reference information.

Network of marks whose planimetric coordinates are known with precision according to the reference systems which are used in Belgium.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 2. This dataset contains measurements on the 7-Ethoxyresorufin-O-deethylase (EROD) activity in Limanda limanda, Imposex (OTIN in Mytilus edulis), fish diseases and counts of oiled common guillemots in the Belgian part of the North Sea.

The dataset describes the physical habitats in the Belgian Part of the North Sea. It uses the EUNIS classification system as well as the MSFD Habitat codelist for the description and classification of the BPNS. It provides also information on the energy, biozone and type of substrate for the different areas in the BPNS.

Hail products are derived from the observed vertical profiles of radar reflectivity and the NWP vertical profiles of temperature. Three types of products are generated. poh : probability of hail of any size (larger than 0.5 cm diameter)expressed in %. posh : probability of severe hail(larger than 2cm)expressed in %. mesh : maximum expected size of hailexpressed in mm of hailstone diameter. All products are generated every 5 minutes. This product is not publically available yet.
