MERIS IPWV VALIDATION : A MULTISENSOR EXPERIMENTAL CAMPAIGN IN THE CENTRAL ITALY

This paper reports the results of an experimental campaign carried out in the Central Italy, considering also part of the Tyrrhenian Sea. Integrated precipitable water vapour estimates obtained from measurements of multiple sensors were produced for a period of about one year, with the purpose of validating the corresponding MERIS estimates. The validation is performed both at specific locations and over an extended area, considering ground based instruments (microwave radiometers, GPS receivers, radiosoundings) and satellite borne radiomenters (Special Sensor Microwave Imager Radiometer, ENVISAT Microwave Radiometer).
