MARG Project - Microwave Areal Rain Gauge

About the project

Radar AccumulationsThe  estimation  and quality  of  recorded  rainfall  play  a  vital  role  in  the performance  of  the European sewer  systems,  water  treatment  plants, irrigation requirements  and  advanced  recognition  of  a developing  flood  threat.  Heavy  rain  frequently overwhelms  urban  sewage  systems,  which  cause  rapid flooding  in  cities. The unnecessary use  of  water  for  irrigation  on  farms  increases  costs  significantly.  Accurate, local  level  rainfall  data  is critical for customers of weather data service providers, as they can save multimillion euros on rainfall related investment for improving these systems.  Currently,  the  common  methods  to  measure  rainfall  include  the  use  of  rain  gauges  or  long  range weather  radars.  Rain  gauges  are  used  for  direct  measurement  of  rainfall  intensity  near  land.  As  rain gauge measures precipitation in one single point, a network application of gauges is necessary  to  keep  deviation  less  than  5  %.  To  own  and  operate  an  individual  rain  gauge  often  cost  as much as € 1100 in a month (including 25% of essential maintenance and repair cost). For a company to own and operate a network of 50 gauges the annual costs can approach 300,000 €. Rain gauge networks are often poorly designed and sited which result in unreliable data that cannot be used. The loss of cost can reach 75%. Long range weather radars work as very densely situated rain gauges, but the price  of  long range  weather  radars  are  not  affordable  for  large  part  of  end-users,  especially  for  SMEs.  Participating SMEs of the MARG project realized that there is a clear need for a cheaper and innovative measurement device. The MARG project aims to develop an innovative, accurate, real-time and user friendly measurement system monitoring spatial distribution and intensity of rain in rural and urban scale for commercial weather data and value-added forecast product suppliers.
