Abstract

In the evening of Sept. 6, 2004, as part of the Southern Italy Eaquate campaign, the Proteus aircraft flew four times over a moderately thick high cirrus cloud in the Potenza region, southern Italy. The evolution of the cloud was monitored by the DIFA Raman lidar ground station in Potenza and four radiosondes were released from the IMAA ground station (8 km far from the DIFA location), both providing potentially an excellent description of the atmospheric gaseous and particulate state. The general evolution of the cloud field was monitored using MSG infrared images, available every 15 minutes. Among the instrument flying on Proteus, the sensor NAST-I is used to compare with accurate radiance simulations based on the description provided by the ground based instrumentation and radiosondes. Considered the quality of the comparison among simulated and measured radiances, the vertical structure of fluxes and cooling/heating rates is computed thus providing a link between the measured state and the time evolution of the cirrus cloud.
