A climate normal is an average over a 30-years period. The period 1981-2010 is the current reference period recommended by the World Meteorological Organization (WMO). Recent climate normals are available for any locations in Belgium and several parameters including air temperature, precipitations and solar radiation. Climate normals for the reference period 1981-2010 are available for air temperature, precipitation and derived parameters (e.g., annual number of summer days, annual number of precipitation days, etc.). For solar radiation, the reference period had to be adjusted to 1984-2013 because of data availability. These climate normals are available as maps and as table for each Belgian municipality.

The climate statistics are derived from 30-years long observations timeseries in Belgium spatially interpolated on the Belgian territory.
Volume reflectivity data - Jabbeke weather radar
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.
Reflectivity data are collected at 15 elevation angles between 0.3 and 25 degrees. A Doppler filtering is applied. An electronic calibration is regularly performed and the quality of the data is monitored using comparison between radar-based precipitation estimates and rain gauge measurements.
This dataset comprises historical orthophotos from the 2010s to 2019, derived from aerial surveys carried out by the National Geographic Institute (NGI). The ground sample distance (GSD) of the images ranges from 25 to 100 cm. The mosaics were created using aerial photography campaigns dating from 2010, 2011, 2012, 2013, 2014 and 2015. The original photographs were digitised and orthorectified in the Lambert 2008 coordinate system. The spatial coverage for each year corresponds to the areas for which photographs were available. High-resolution data can be ordered via https://shop.ngi.be/fr/photos-aeriennes/

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.
Summer and winter mean temperature given in °C. The temperature 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.
Summer and winter maximum daily precipitation given in mm/day that occur once in a year and once in 5, 10, 15 and 30 years (i.e. return periods of 1 year and 5, 10, 15, 30 years). The precipitation extremes are available for the future target year 2085, which corresponds to the middle of the 30-year period 2071-2100, and for mean and high impact scenarios corresponding respectively to the 50th and 95th percentiles of the change factors.
This dataset comprises historical orthophotos from the 1950s to 1959, derived from aerial surveys carried out by the National Geographic Institute (NGI). The ground sample distance (GSD) of the images is 50 cm. The mosaics were created using aerial photography campaigns dating from 1951, 1952 and 1954. The original photographs were digitised and orthorectified in the Lambert 2008 coordinate system. The spatial coverage for each year corresponds to the areas for which photographs were available.

The composite is produced every 5 minutes using the reflectivity data from the Wideumont and Jabbeke weather radars. This product is not publicly available yet.
The rainfall composite combines 2D products from the Wideumont, Jabbeke and Zaventem weather radars. Reflectivity values are converted into rainrates using the Marshall-Palmer relation. For each pixel, the maximum value of the three products is taken. The effective coverage of the composite is smaller than the bounding box. It is determined by the maximum ranges of the three radars, i.e. 250 km for Wideumont, 300 km for Jabbeke, and 250 km for Zaventem.
INSPIRE download service for the IDOD database-WFS
INSPIRE compliant download service for geographic information of marine datasets made available by the Royal Belgian Institute for Natural Sciences (RBINS) in the IDOD (Integrated and Dynamical Oceanographic Database) database.
Annual temperature extremes given in number of days: 1/ Total number of heatwaves occurring once in 20 years; 2/ Maximum length of the heatwaves occurring once in 20 years; 3/ Hot days: Mean annual number of days with maximum temperature > 25°C; 4/ Tropical days: Mean annual number of days with maximum temperature > 30°C; 5/ Frost days: Mean annual number of days with minimum temperature < 0°C. Heatwaves are defined according to the Royal Meteorological Institute of Belgium when the maximum temperature in Uccle is >= 25°C during at least 5 consecutive days, during which at least 3 days the maximum temperature is >= 30°C. The temperature extremes are available for the future target year 2085, which corresponds to the middle of the 30-year period 2071-2100, and for mean and high impact scenarios corresponding respectively to the 50th and 95th percentiles of the change factors.
