The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 5 nature conservation areas: Special area for conservation 'The Flemish Banks' (Art. 7§1), Special area for conservation 'Vlakte van de Raan' (Art. 7§3), Special protection area for birds - SPA 1 (Art. 7§5.1°), Special protection area for birds - SPA 2 (Art. 7§5.2°), Special protection area for birds - SPA 3 (Art. 7§5.3°). It replaces the 2014 Marine Spatial Plan, which is included for completeness. The Royal Decree of 20 March 2014 establishing a marine spatial plan defines in its Art. 7., six nature conservation sites: two special areas for conservation (Art. 7. §1, Special area for conservation 'Vlaamse Banken' and Art. 7. §3, Special area for conservation 'Trapegeer stroombank'), three special protection zones for birds (Art7§4.1°, SBZ1, Art7§4.2°, SBZ2, Art7§4.3°, SBZ3), and one marine reserve (Art7§8, Marine reserve 'Baai van Heist'). These zones are made available digitally in the resource described by this metadata document. Please refer to the Belgian official gazette (\"Moniteur belge/Belgisch Staatsblad\") for official reference information.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 4 aquaculture zones: Zone 1 for aquaculture (Eastern zone) (Art. 14§1), Zone 2 for aquaculture (Noordhinder Noord) (Art. 14§2), Zone 3 for aquaculture (Noordhinder Zuid) (Art. 14§3), Zone 4 for aquaculture (Fairybank) (Art. 14§3). It replaces the 2014 Marine Spatial Plan, which is included for completeness. The Royal Decree of 20 March 2014 establishing a marine spatial plan defines in its Art. 10, two zones for sustainable aquaculture: Zone 1 for sustainable aquaculture, Art. 10 § 2 Zone 1; Zone 2 for sustainable aquaculture, Art. 10 § 2 Zone 2. These zones are made available digitally in the resource described by this metadata document. Please refer to the Belgian official gazette (\"Moniteur belge/Belgisch Staatsblad\") for official reference information.

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 Royal Decree of 20 March 2026 establishing the marine spatial plan for the period 2026 to 2034 in the Belgian marine areas defines 1 coastal protection experiments zone: Coastal protection belt (Art. 20§2). It replaces the 2020 Marine Spatial Plan. Please refer to the Belgian official gazette ("Moniteur belgeBelgisch Staatsblad") for official reference information.

RADQPE provides high resolution radar-based quantitative precipitation estimation in realtime for Belgium and its surroundings. This product is not publically available yet.

The national wastewater-based epidemiological surveillance of influenza (commonly known as flu) monitors the influenza presence in several wastewater treatment plants across Belgium. This dataset contains the results per treatment plant since the beginning of the surveillance in January 2024. The results consist of the influenza concentrations over time as well as other data needed for the interpretations such as the flow rates of the treatment plants and the population covered.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 7, criterion 1. This dataset describes the impact of an offshore windmills farm on the hydrodynamics in the Belgian part of the North Sea (BPNS). Originally, it is a NetCDF file with the results of the reference simulation made with the COHERENS (COupled Hydrodynamical Ecological model for REgioNal Shelf seas) hydrodynamic model only forced by tides (no wind effect). Model resolution : ~ 12.5m. It contains both the reference situation which is a simulation without any windmill and the modeling result of the influence by the windmills on the hydrodynamic in the BPNS. The dataset contains the results on the most inner nested grid level for one reference spring-neap cycle: - hourly sea surface elevation - hourly bottom shear stress - hourly 3D horizontal velocity components (u,v) - hourly 3D eddy viscosity - time-averaged bottom shear stress over the reference spring-neap cycle - percentile 90 of the bottom shear stress for the reference spring-neap cycle - percentile 90 of the specific kinetic energy at the sea bed - accumulated time during which sedimentation processes are dominant - accumulated time during which re-suspension processes are dominant.

Distribution of real estate assets - Natural persons corresponds to the dataset relating to the distribution of real estate assets owned by natural persons such as recorded by the FPS Finance for tax purposes. This dataset is composed of eight classes. The first class mentions, at national level, for each age-gender combination, by cadastral income bracket, the number of natural persons with real estate capital valued in the relevant bracket as well as the total and median cadastral income of the parcels held by these persons. The assessment of the cadastral income takes into account the shares actually held. The second class includes this information at the level of the three regions. The following classes do the same at the level of provinces, districts, municipalities, land register divisions and statistical sectors. The last class includes this information at the level of the countries for the natural persons which are not settled in Belgium but wich are nevertheless reigstred in the National Reistry.The dataset can be freely downloaded as a zipped CSV.
