1 MERIS IPWV validation: a multisensor experimental campaign in the Central Italy P. Ciotti (1,4), E. Di Giampaolo (1), P. Basili (2), S. Bonafoni (2), V. Mattioli (2), R. Biondi (2), E. Fionda (3), F. Consalvi (3), A. Memmo (4), D. Cimini (4), R. Pacione (5), F. Vespe (6) (1) DIE-Univ. dellAquila, (2) DIEI-Univ. di Perugia, (3) FUB, Roma, (4) CETEMPS, LAquila, (5) Telespazio, Matera, (6) ASI, Matera MERIS User Workshop ESA/ESRIN November 2003

2 Italian Cal/Val sites over land SiteInstruments Perugia:GPS, meteo station Elba Island:microwave radiometer (WVR), meteo st. & GPS LAquila: GPS, meteo station Pomezia (Rome):microwave radiometer (WVR), RAOBs, meteo st. - MM5 numerical model outputs for each site MERIS User Workshop ESA/ESRIN November 2003

3 The validation is performed both at specific locations (4) and over an extended area including land and sea backgrounds 1.The first comparison is performed with respect to the measurements of ground based instruments (microwave radiometers, GPS, RAOBs) 2.The second assessment is based on IPWV maps of the Tyrrhenian area that are produced by geostatistical interpolation of the measurements of a network of GPS receivers (over land) and measurements of SSM/I (over sea) PURPOSE Validation of the IPVW from the MERIS/ENVISAT MERIS User Workshop ESA/ESRIN November 2003
