Popis: | Errors and uncertainty in radar estimates of precipitation result from both errors in the basic measurement of reflectivity and from attempts to relate this to the precipitation falling at the ground. If radar data are to be used to their full potential it is essential that effective measures are taken to mitigate these problems. The automatic processing of radar data which forms part of the UK Met. Office's Nimrod system addresses a number of specific sources of error.
