Experiments to reveal regions of frequent spurious radar echoes in COST-73 composites

Summary

Radar rainfall data are often contaminated by ground clutter and other spurious returns, not all of which are removed during pre-processing at the radar sites. In the experiments described here, long-period accumulations of COST-73 hourly composites are used to reveal areas of persistent echo and to identify their probable causes. The results allow the likely presence of such artefacts to be taken into account, and if necessary removed, when the COST-73 product is used either as a direct measurement of rainfall or as a means of calibrating Meteosat images to show probable patterns of rainfall.
