Abstract

Cloud systems containing ice particles (“ice clouds”) must be realistically represented in numerical models devoted to weather forecasting and climate projection. Nevertheless, such clouds have not been fully characterized. The RadOn method (after Radar Only) has been developed for estimating microphysical properties of ice clouds from Doppler cloud radar observations. This method is here updated and applied to observations conducted in 2003–2004 with the Doppler cloud radar RASTA at the SIRTA observatory (Palaiseau, near Paris).

Résumé

Les systèmes nuageux contenant de particules de glace ( « nuages de glace ») doivent être représentés de façon réaliste au sein des modèles consacrés à la prévision du temps et à la simulation du climat. Néanmoins, ces nuages ne sont pas suffisamment connus. Cet article présente l’état actuel de la méthode RadOn, conçue pour estimer les propriétés microphysiques des nuages de glace à partir d’observations effectuées à l’aide d’un radar nuage Doppler. L’application de cette méthode aux observations acquises en 2003 et 2004 à l’aide de l’instrument RASTA à l’observatoire SIRTA (Palaiseau) est ici analysée en détail.
