Lidar observations of cirrus clouds in Buenos Aires

Mostrar todas las versiones(2)

Abstract: Characterization of cirrus clouds over Buenos Aires (34.6°S, 58.5°W) using a ground based lidar is presented. The study, carried out for the period 2010–2011, reveals that cirrus are usually found in the altitude region 8–11 km, with mid-cloud temperatures values varying between 75 °C and...
