Denmark precipitation observation networks (stations and radar)

For national purposes, more data concerning precipitation is needed than can be provided from the overall surface climatological and meteorological network described above. In Denmark the precipitation observation network consists of approximately 350 stations. Roughly 100 of these provide data on precipitation intensity on an ongoing basis. They are jointly operated by DMI and The Water Pollution Committee of the Society of Danish Engineers (Spildevandskomitéen - SVK). The remaining 250 stations collect daily values of precipitation, and data from these are electronically transmitted to DMI on a daily basis. On the Faroe Islands a network of 7 precipitation station observe daily precipitation. Information on precipitation can also be obtained from weather radar data. In Denmark, DMI runs a network of four weather radars which provides 100% coverage of Danish land areas and coastal marine areas. The network s geographical coverage is unsurpassed, and hence provides detailed information about precipitation on national and local scales. By calibrating radar data against point measurements of precipitation the latest scientific results show a high absolute accuracy.
