The work methodology is based both on field measurements and on numerical simulations. The assessment is related to tidal, wind and atmospheric pressure for the whole 2016, taken as exemplary year. Field measurements have been conducted by means of level gauges, installed at four internal lagoon points, and one anemometer installed at a central internal point. Moreover, two tidal gages, one located at Civitavecchia harbor and the other at Marina di Campo (Elba Island) have been used to set the offshore boundary conditions for the numerical model. The numerical simulations have been conducted with the HD FM module of the MIKE21 software package, a fully non-linear shallow water solver. The numerical results match closely the field measurements, in terms of total sea-lagoon water exchange, but the former also permits to simulate the whole lagoon hydrodynamics thus allowing much deeper understanding of this physical system. In fact, the numerical simulation has also permitted understanding of the fraction of total water exchange taking place at each of the three lagoon channels connecting the lagoon to the sea.","PeriodicalId":252792,"journal":{"name":"2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea)","volume":"222 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120832505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mitigation of leverage observation effects in GNSS robust positioning GNSS稳健定位中杠杆观测效应的缓解

On the other hand, in harsh scenarios GNSS performance are degraded, owing to the shortage of available measurements and/or to the presence of blunders among them. The blunder issue is usually addressed through RAIM techniques or robust estimation; the latter approach demonstrates often better performance, but suffers anyway the cases of multiple blunders and low redundancy. M-estimators, a particular class of robust estimators, are based on the minimization of functions of least squares residuals. A possible way to strengthen a M-estimator is to take into account for leverage observations, defined as measurements with high potential to affect estimation results. In this work, the Huber M-estimator is adapted to include information about leverage observations and is used to process GPS measurements, collected in harsh environment. The obtained results are very promising, with position errors reduction even beyond 50% with respect to classical Huber method.","PeriodicalId":252792,"journal":{"name":"2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115330999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the range of remote sensing methods available to produce measurement of the coastline, this study tests the utility of low-altitude aerial imagery by Unmanned Aerial Vehicle (UAV) on the beaches of Serapo and S. Agostino, located in the Latinum region, in the Thyrrenian Sea, and spaceborne Synthetic Aperture Radar (SAR) measurements which are processed with the purpose of exploiting the dual-polarimetric information to better distinguish land from sea.The dataset consists of two sets of images, both acquired by UAV and SAR platforms, the first in December 2013 and the second in June 2018. A comparison of the coastline extraction obtained with the same technique in two different temporal sequences and between different techniques in the same period has been performed in order to assess benefits and limitations of each methodology.","PeriodicalId":252792,"journal":{"name":"2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126520215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main reason is because, despite a clear definition of salinity, the realization of the unit is still linked to the use of artifact of natural origin characterized by measurements of conductivity. The latter seems to be the only quantity capable to guarantee the necessary accuracy at the moment. However, the concept of salinity, but not the definition, is linked to the quantity of substance contained in seawater, that is not pure water, and conductivity measurement can only partially cover the physico-chemical aspects characterizing the thermodynamic behavior of seawater. In these cases, the measurement of the density is more appropriate and, thanks to its recent progresses, it seems to be a promising way to guarantee the traceability of salinity measurement in seawater. This work is a contribution to the measurement of the density of IAPSO standard seawater, using the method of hydrostatic weighing. Despite this method is limited to work at atmospheric pressure, it is the best approach in term of accuracy. The measurement method is, mainly, analyzed from the metrological point of view, focusing on the traceability chain supporting the reliability of the obtained results.","PeriodicalId":252792,"journal":{"name":"2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115115212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
