However, the spatial and temporal continuity of remote sensing data are inevitably influenced by the limitation of sensor resolution and cloud contamination, which prevent the highly dynamic monitoring of water quality in inland median and small water bodies. Spatial and temporal fusion (STF) provides an effective way to address this issue. However, the errors might be introduced into the remote sensing reflectance () in the pre-processing and fusion process, which might bring large uncertainties in the derived Chla datasets. In this paper, an analytical study was designed to understand the influence of using different atmospheric correction processors for generating the images in STF, and the accuracy of the estimated Chla using the corresponding fusion images was validated with the in-situ samples. The experimental results show that ACOLITE DSF processor achieved the best performance for processing Multi-spectral Instrument (MSI) and Ocean and Land Color Instrument (OLCI) images in the atmospheric correction tests. Moreover, the machine-learning based Chla inversion accuracy of fusion images was comparable with that of real MSI images.","PeriodicalId":207141,"journal":{"name":"Proceedings of the 2023 12th International Conference on Informatics, Environment, Energy and Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127793071","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 information obtained is the molecular mass to charge ratio of analytes. To reach a high accuracy and resolving power, time of flight devices need to be large so that the ions can fly for long times before they are detected. Using a reflector at the end of the flight distance allows using at least part of this distance twice, thereby increasing the resolving power. These reflectors should reflect ion packages without changing them. Furthermore, modern reflectors allow compensating differences of kinetic energy that the ions of same mass might possess. In 2016, a patent has been published proposing a reflector for time of flight mass spectrometry based electric fields with the shape of Cassinian Ovals, similarly to a Cassinian Ion Trap. In this paper we have used finite elements method simulations in order to characterize such a reflector, thereby showing how well it can fulfill its purpose regarding the previously mentioned points, i.e. not changing the ion packets and allowing for energy difference compensation.","PeriodicalId":207141,"journal":{"name":"Proceedings of the 2023 12th International Conference on Informatics, Environment, Energy and Applications","volume":"292 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133679599","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}
