In order to improve knowledge in real time of the three-dimensional distribution of precipitation and to forecast rain more accurately within a range of a few hours the Meteorological office has set up a radar network which will make it possible to plot precipitation every fifteen minutes with an accuracy of several kilometers over the major part of France. This network consists of 10 radars with 5 or 10 cm wavelengths. Each radar is provided with a digital system which controls the aerial acquisition and processing of data and telephonic transmission of the resultant pictures. A processing centre in Paris will receive the pictures from III the radars and establish composite precipitation charts at national level. The data will be analysed in relation to satellite information and other meteorological data available at the central data bank. Great efforts will be made to promote extremely rapid dissemination of the pictures to III meteorological staions and other interested users. The latter will be able to in stall METEOTEL picture reception cabinets, so that they can receive pictures direct from a given radar or the composite picture established in paris.
