Polar volume reflectivity data from the Jabbeke weather radar. Volume data files are produced every 5 minutes from a multiple elevation scan. This product is not publicly available yet.

Bird density profiles are derived from weather radar volume data in real time, by the vol2bird algorithm as described in Dokter et al. (2011, 2019). The vol2bird algorithm exploits the radar reflectivity characteristics of different scatterers in the atmosphere, in order to distinguish biological from non-biological radar echoes. Once biological scatterers are isolated in the volume files, the reflectivity of these scatterers is converted in an estimate of the bird density per vertical layer of 200m, using a mean cross section of 11 cm2. The vbird profiles are provided for the following radars, with the radar owner in parentheses: Jabbeke (RMI), Wideumont (RMI), Helchteren (VMM), Zaventem (Skeyes), Herwijnen (KNMI), Den Helder (KNMI), Neuheilenbach (DWD), Essen (DWD), Abbeville (Météo-France) and Avesnois (Météo-France).

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.

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

RADCLIM is a historical dataset based on weather radar observations that provides gridded accumulated precipitation composites over Belgium and surrounding regions. The data are distributed in ODIM_H5 version 2.2 format. The reported quantity is accumulated precipitation (ACRR) for 5-minute and 1-hour accumulation periods. UTC is used as the time reference, and the timestamp in the filename corresponds to the end of the accumulation period. The dataset is produced on a 700 × 700 grid with 1 km spatial resolution in the Belgian Lambert 2008 projection (Lambert Conformal Conic).

Land register plan - current situation corresponds to the dataset of land register from the reference database for the land register data CadGIS. The land register plan is one of the elements that make up the patrimonial documentation. It is defined as “the graphic representation and assembling on a plan of all the cadastral plan parcels of the Belgian territory”. A plan parcel, such as defined in Article 2 of the Royal Decree of 30 July 2018, is a part of Belgian territory, geographically delimited and identified by the General Administration of Patrimonial Documentation on the land register plan, which corresponds to the ground surface area of one or more patrimonial cadastral parcel(s) (real estate property as mentioned in Article 472 of the 1992 Income Tax Code in respect of which the cadastral income is fixed). This dataset corresponds to the current situation at the time of consultation. It is composed of fourteen geometric layers. The first five are the administrative units, namely the country, the regions, the provinces, the districts and the municipalities. The sixth and seventh layers correspond to the cadastral units, divisions and sections. the eighth layer includes the cadastral blocks, the ninth, the property stones, the tenth, the addresses, the eleventh, the polders and wateringues, the twelfth, the cadastral plan parcels, the thirteenth the buildings managed by the AGDP, and the fourteenth, buildings managed by the regions. The dataset is freely downloadable via the ad hoc WFS.
