    • Aerosol Optical Properties and Type Retrieval via Machine Learning and an All-Sky Imager 

      Logothetis, Stavros-Andreas; Giannaklis, Christos-Panagiotis; Salamalikis, Vasileios; Tzoumanikas, Panagiotis; Raptis, Panagiotis-Ioannis; Amiridis, Vassilis; Eleftheratos, Kostas; Kazantzidis, Andreas (Peer reviewed; Journal article, 2023)
      This study investigates the applicability of using the sky information from an all-sky imager (ASI) to retrieve aerosol optical properties and type. Sky information from the ASI, in terms of Red-Green-Blue (RGB) channels ...

    • Real-time UV index retrieval in Europe using Earth observation-based techniques: system description and quality assessment 

      Kosmopoulos, Panagiotis G.; Kazadzis, Stelios; Schmalwieser, Alois W.; Raptis, Panagiotis I.; Papachristopoulou, Kyriakoula; Fountoulakis, Ilias; Masoom, Akriti; Bais, Alkiviadis F.; Bilbao, Julia; Blumthaler, Mario; Kreuter, Axel; Siani, Anna Maria; Eleftheratos, Kostas; Topaloglou, Chrystanthi; Gröbner, Julian; Johnsen, Bjørn; Svendby, Tove Marit (Peer reviewed; Journal article, 2021)
      This study introduces an Earth observation (EO)-based system which is capable of operationally estimating and continuously monitoring the ultraviolet index (UVI) in Europe. UVIOS (i.e., UV-Index Operating System) exploits ...

    • Retrieval of Aerosol Optical Properties via an All-Sky Imager and Machine Learning: Uncertainty in Direct Normal Irradiance Estimations 

      Logothetis, Stavros-Andreas; Giannaklis, Christos-Panagiotis; Salamalikis, Vasileios; Tzoumanikas, Panagiotis; Raptis, Panagiotis-Ioannis; Amiridis, Vassilis; Eleftheratos, Kostas; Kazantzidis, Andreas (Journal article, 2023)
      Quality-assured aerosol optical properties (AOP) with high spatiotemporal resolution are vital for the accurate estimation of direct aerosol radiative forcing and solar irradiance under clear skies. In this study, the sky ...
