| Zusammenfassung |
| The local weather radar of Lyon, part of the Aramis
network of Meteo-France, is currently located 40 km from the urban
community. The measurement quality of this tool is subjected to constant
improvements from Meteo-France. Indeed, its hydrological measurement quality
has steadily evolved from the early 90's until today. This article,
therefore, proposes a return on these innovations, assessing measurement
quality over the territory of Greater Lyon. This study is based on two
successive radar locations, and also on raw reflectivity data and on rain
accumulation over the past 15 min (Hydram) or 5 min (Panthere). The measurement
performed on the site Satolas was unsatisfactory because of too many ground
clutters; and therefore the radar was moved to Saint-Nizier. This new
location associated with radar Hydram rain accumulation has reduced the problem of
ground clutters. These rain accumulation data have given correct results in
comparison with local data of the raingauge network of Greater Lyon, after a
global and spatially uniform correction, based on these gauges. The latest
generation of radar rain accumulation (Panthere) has, nearly completely, eliminated
the problem of ground clutter in the urban area and provides very
satisfactory measurements, especially during intense rain events. |
