Abstract
High temporal and spatial resolution measurements by both space-borne and ground-based instruments are therefore necessary to monitor atmospheric water vapor for climate purposes. Lidar techniques can accomplish ground-based measurements of atmospheric water vapor with high space and time resolution. A lidar system capable to perform simultaneous measurements of atmospheric water vapor and aerosols has been developed in Potenza, Southern Italy, in the context of a cooperation between the Universita della Basilicata and Istituto di Metodologie Avanzate di Analisi Ambientale. An intensive measurement campaign was performed during 1997 in Potenza aimed to the simultaneous application of the Raman and DIAL techniques for water vapor ground- based lidar measurements. Raman and DIAL humidity measurements performed during 1997 in Potenza aimed to the simultaneous application of the Raman and DIAL techniques for water vapor ground-based lidar measurements. Raman and DIAL humidity measurements performed at night in the Planetary Boundary Layer have been compared with simultaneous radiosonde data obtained from both free and captive balloons. The agreement among Raman, DIAL and radiosonde data is found to be within 30 percent up to approximately 1.5 km. Results from this measurement campaign will be reported and discussed in this paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
