15 years of Weather Radar Technology at DHI

What started as a research project for a short-term rainfall prediction system 15 years ago has evolved into a valuable Local Area Weather Radar (LAWR) system that has since been installed in more than 35 locations worldwide.

The initial objective of the rainfall prediction system was to enable better control of sewer systems and wastewater treatment plants during rain. Together with the Danish Meteorological Institute (DMI), we developed the very first LAWR in 1999. 

Today, LAWR systems are widely used in various organisations, including:
  • Water management companies 
  • Waste water authorities 
  • Waste water treatment plants
  • Municipalities and other official authorities  
  • Meteorological services 
  • Road authorities 
  • Flood authorities 
‘Apart from precipitation estimates,’ explains Niels Einar Jensen, Product Manager, DHI Weather Radar System, ‘LAWRs are also used in environmental impact studies, for example, to study the behaviour of migrating birds around bridges and wind farms.’

Its versatility and popularity continue to be evident all over the world. A countrywide network of LAWRs was installed in El Salvador from 2010 to 2013, and the city of Quito, Ecuador, is now in the process of installing a network of three radars. 

‘The LAWR system is constantly undergoing improvements for an even better client experience. We will continue to enhance its software and hardware to meet the needs of our clients,’ added Niels.

The latest weather radar was installed in La Paz, Bolivia.


The first commercial LAWR was installed at Søsterhøj south of Aarhus in December 1999.
