ROB Database of Absolute and Relative Gravity Measurements
The Belgian gravimetric database consists of 69,000 measurements, made using relative spring gravimeters. This database is managed by the Royal Observatory of Belgium since 1925. Two superconducting gravimeters measure elusive gravity variations at the stations of Membach and Rochefort, with a precision better than 1E-10 of gravity at the surface of the Earth (g). Since 1996, an absolute gravimeter performs repeated gravity measurements at selected sites, with an accuracy of 1E-9 g.

The measurements are performed and processed by the Royal Observatory of Belgium and the National Geographical Institute. The data base is continuously completed with ongoing measurements.
User reports from the RMI smartphone app
Since August 2019, users of the RMI smartphone app are able to send an observation of the meteorological conditions at a certain place and a certain time. The observations provide information about the weather conditions and potentially severe weather to the other users and to RMI. The collection of citizen weather reports is a valuable complement to the information obtained with the classical instruments like stations, radar and satellite. The data can be exploited for nowcasting, warnings and model verification, and eventually in assimilation. A general introduction of the data and their characteristics can be found in Reyniers et al. (2023). A basic quality control is implemented on the received observations via a plausibility check. This plausibility check determines whether an observation is plausible, suspicious or false, by comparing it to the INCA-BE nowcasting system using a simple thresholding scheme. INCA-BE is RMI's operational nowcasting system described in Reyniers et al. (2021). There is no strict spatial extent since there is no restriction at the input side: users can send observations from all over the globe. The bulk of the observations are received from within Belgium. Note that the plausibility check is not available for reports from outside Belgium.

A basic quality control is implemented in the form of a plausibility check. Possible outcomes of this plausibility check for the validity of an observation are: 'possible', 'suspicious' or 'false'. This assessment is made immediately after the reception of the observation by comparing it to the latest INCA-BE output. There is no offline revision of this plausibility at a later time.
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.

In the follow-up Belspo funded 'CICADA' project (2019-2021, https://www.belspo.be/belspo/brain-be/projects/FinalReports/CICADAbe_FinRep.pdf), these Belgian climate model projections were used to adjust the spread of climate change signals based on the larger model ensemble of all available CMIP5 Global Climate Model runs (https://pcmdi.llnl.gov/mips/cmip5/) and EURO-CORDEX Regional Climate Model runs (https://euro-cordex.net/060378/index.php.en). This multi-model ensemble of climate change signals or factors were used to apply a statistical downscaling or more specifically a quantile perturbation method on the observational climate grid from the Royal Meteorological Institute of Belgium. From those ensembles, 5th, 50th, and 95th percentiles of changes, corresponding to a mean (50th percentiles) and high (5th or 95th percentiles) impact scenario, were obtained for the variables: precipitation, temperature, relative humidity, wind speed, global solar radiation and potential evapotranspiration.
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.
Network installed and maintained by the Royal Observatory of Belgium since 1889 (seismic stations) and 1999 (accelerometric stations)
Network of marks whose planimetric coordinates are known with precision according to the reference systems which are used in Belgium.
Phased survey process which started in the inter-war period and ended in 2004.
Key indicators on future Belgian climate
Mean key indicators on future climate for Belgium for precipitation, temperature, relative humidity, wind speed, global solar radiation and potential evapotranspiration (spatial distributions are available through the WMS view service). The key indicators are derived from a multi-model ensemble of climate change signals or factors for a mean and high impact scenario (corresponding to respectively the 50th, and 5th or 95th percentile of the change factors), and for multiple future target years (2030, 2050, 2085, 2100).
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.

Hail detection module is an implementation of two hail detection algorithms: of Witt and of Waldvogel (Waldvogelet al., 1979). The module takes radar observations and temperature information and estimates probability of hail (POH, %), probability of severe hail (POSH, %) and maximum expected size of hail (MESH, mm). The implementation of the Waldvogel algorithm is based on the Holleman's equation (I. Holleman, 2001), which was verified for Belgium by Delobbe et al. (2003). The POH is derived in the algorithm from the presence of a substantial updraft detected above the freezing level (0º-isoterm). The implementation of the Witt algorithm is based on the weighted integration of the reflectivity values between the heights of 0º-isoterm and -20º-isotherm (Witt et al., 1998). This algorithm provides POSH and MESH estimates.
Average private household size - Wallonia
The average household size of private households by 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 or marriage (in the case of cohabitation, for example). A household may consist of only one person. Statistics: Household data are taken from the National Register (NR) by Statbel and are based on the official population of Belgium (without the waiting register). A new household typology was adopted in 2015 by Statbel. This typology, which is close to the LIPRO typology developed at the Netherlands Interdisciplinary Demographic Institute (NIDI), makes it possible to reconstruct cohabiting households by algorithm, even if they are not declared as such in the National Register. The datasets presented here are for private households only.
View service - Digital surface model Meuse, Vesdre and Demer
This webservice allows viewing a digital surface model. It is a homogeneous and regular points grid which indicates the height above the surface of the earth, either the soil or any other permanent and visible element in the landscape (vegetation, construction,…). These data represent the situation of the landscape resulting from the July 2021 floods in het areas of the Vesdre, of part of the Meuse downstream from Liège and of the Demer. The heights are given relative to the Belgian zero level (fictitious zero of Uccle). The data have a resolution (size of the meshes of the regular grid) of 20 cm.
Buyers' origin - Real estate companies corresponds to the dataset describing the origin of the buyers (legal persons engaged in real estate activities as defined in section L of the NACE-BEL 2008 nomenclature) of real estate located in Belgium according to the municipality of their headquarters for legal persons settled in Belgium and according to the country or territory of their headquarters for foreign legal persons (headquarter at the date of the deed). This dataset is made up of seven classes. The first class shows, at national level, for each type of property, the total number of parcels, the number of parcels acquired by buyers from each Belgian municipality and the number of parcels acquired by buyers from each country or territory. The number of parcels takes into account the shares actually acquired. The second class shows this information at the level of the three regions. The following classes do the same at the level of provinces, arrondissements, municipalities, land register divisions and statistical sectors. The dataset is freely downloadable, in the form of zipped CSV files.
The licence is fully available in French (https://finances.belgium.be/sites/default/files/Licence_plan_opendata_FR.PDF) or in Dutch (https://financien.belgium.be/sites/default/files/Licentie_plan_opendata_NL.PDF).
Buyers' origin - Real estate companies is compiled from the contents of the reference database for the record of real estate deeds. The database records for each deed, the real right concerned, the identification of the parties and the situation of the real estate property concerned as well as its land register nature. The second database contains various items of information for each legal person from the Crossroads Bank for Enterprises, the authentic source for legal persons.
