The Royal Meteorological Institute, IRM/KMI (, founded in 1833, is the Belgium’s leading research and services centre for meteorology and climatology, with also long-time observation and research traditions in geophysics, including ionospheric and space physics, atmospheric physics, and geomagnetism. The institute employs about two hundred people working in six departments at two locations in Belgium: Brussels and Dourbes.

The IRM/KMI Ionosphere and Space Weather (ISW) section ( caries out regular ionospheric and space observations by means of an own vertical incidence sounder (digital ionosonde, see, GNSS signal receivers located in Belgium, and a cosmic ray detector. The ISW research activities are currently focused on the ionospheric disturbances and their effects on the technological systems dependent on radio wave propagation. The IRM/KMI research expertise, broad experience, and modern infrastructure are well recognised and the institute is regularly being involved in various international projects sponsored by the EC, ESA, GJU, and NATO.
