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.

The Solar Ultraviolet - Visible Irradiance Monitoring network (SUVIM) is formed of observation stations operated by the Royal Belgian Institute for Space Aeronomy (IASB-BIRA). At each station, UV solar radiation is measured by several instruments. The network produces UV indices, solar irradiances and ancillary measurements such as meteorological conditions at the stations in quasi-real time. The SUVIM Station Network dataset includes information on the stations. It does not include the measured data, which form the SUVIM Observations dataset.

The climatological network contains about 200 stations spread over the whole country. It consists of voluntary observers recruited by the RMI, professional observers of Skeyes (civil aviation) or the Air Force (military aviation) and civil servants of the state, communities or private companies. The observers measure the amount of rain fallen in the last 24 hours in the pluviometer of the RMI every morning at 8 o‘clock. In more than half of the stations the extreme air temperatures are also recorded by reading the maximum and minimum temperature in a standardized weather shelter. The observers send their observations either on a  daily or on a monthly basis to RMI. This product is not publicly available yet.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 1. This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 1. This dataset contains the concentrations of priority substances (tributyltin, polycyclic aromatic hydrocarbons (PAHs) and polybrominated diphenylethers (PBDEs)) measured in the water column at three stations in the Belgian part of the North Sea between 2009 and 2014 (as reported in the frame of the WFD in 2016). In total, 45 different parameters are measured.

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.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 20 shipping and ports zones: Shipping regular regime (Art. 10§1), Northbound traffic flow starting at separation line 'Noordhinder Sud' (Art. 10§2.1°), Separation zone 'Noordhinder Sud' (Art. 10§2.1°), Precaution zone 'Near Thornton and Blighbank ' (Art. 10§2.10°), Northbound traffic flow starting at separation zone 'Off Noordhinder' (Art. 10§2.2°), Separation zone 'Off Noordhinder' (Art. 10§2.2°), Southbound traffic flow starting at separation line 'Off Noordhinder' (Art. 10§2.2°), Precaution zone 'Noordhinder Jonction' (Art. 10§2.3°), Eastbound traffic flow starting at separation line 'At West Hinder' (Art. 10§2.4°), Eastbound traffic flow starting at separation zone 'At West Hinder' (Art. 10§2.4°), Precaution zone 'At West Hinder ' (Art. 10§2.4°), Separation zone 'At West Hinder' (Art. 10§2.4°), Westbound traffic flow starting at separation line 'At West Hinder' (Art. 10§2.4°), Area to be Avoided 'At West Hinder' (Art. 10§2.6°), Deep water route 'Westerschelde approach' (Art. 10§2.7°), Border line 1 of two-way shipping lane 'Westpit' (Art. 10§2.8°), Border line 2 of two-way shipping lane 'Westpit' (Art. 10§2.8°), Precaution zone 'At Gootebank' (Art. 10§2.9°), Anchoring zone 'Oostdyck' (Art. 10§3.1°), Anchoring zone 'Westhinder' (Art. 10§3.2°). 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. 9, nine zones with regards to shipping and ports: seven shipping zones (Shipping regular regime, Art. 9 § 1; Shipping route Northhinder South, Art. 9 § 2.1°; Shipping route Northhinder junction, Art. 9 § 2.2°; Shipping route Westhinder, Art. 9 § 2.3°; Shipping route Westhinder precautionary area, Art. 9 § 2.4°; Shipping route Westhinder area to be avoided, Art. 9 § 2.5°; Deep water shipping route Western Scheldt approach, Art. 9 § 2.6°) and two anchorage places (Anchorage place 'Oostdyck', Art. 9 § 4.1° and Anchorage place 'Westhinder', Art. 9 § 4.2°). 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.
