    • Analysis of Air Mean Temperature Anomalies by Using Horizontal Visibility Graphs 

      Gómez-Gómez, Javier; Carmona-Cabezas, Rafael; Sánchez-López, Elena; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (MDPI, 2021)
      The last decades have been successively warmer at the Earth’s surface. An increasing interest in climate variability is appearing, and many research works have investigated the main effects on different climate variables. ...

    • Can complex networks describe the urban and rural tropospheric O3 dynamics? 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2019)
      Tropospheric ozone (O3)time series have been converted into complex networks through the recent so-called Visibility Graph (VG), using the data from air quality stations located in the western part of Andalusia (Spain). ...

    • Checking complex networks indicators in search of singular episodes of the photochemical smog 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2020)
      A set of indicators derived from the analysis of complex networks have been introduced to identify singularities on a time series. To that end, the Visibility Graphs (VG) from three different signals related to photochemical ...

    • Multifractal characterisation of particulate matter (PM10) time series in the Caribbean basin using visibility graphs 

      Plocoste, Thomas; Carmona-Cabezas, Rafael; Jiménez-Hornero, Francisco José; Gutiérrez de Ravé Agüera, Eduardo; Calif, Rudy (Elsevier, 2021)
      A good knowledge of pollutant time series behavior is fundamental to elaborate strategies and construct tools to protect human health. In Caribbean area, air quality is frequently deteriorated by the transport of African ...

    • Multiplex Visibility Graphs as a complementary tool for describing the relation between ground level O3 and No2 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2020)
      The usage of multilayer complex networks for the analysis of correlations among environmental variables (such as O3and NO2concentrations from the photochemical smog) is investigated in this work. The mentioned technique ...

    • Wet scavenging process of particulate matter (PM10): A multivariate complex network approach 

      Plocoste, Thomas; Carmona-Cabezas, Rafael; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2021)
      This paper reports the results of research on PM10 wet scavenging by rainfall using a new multilayer complex networks called Multiplex Visibility Graphs (MVG). To the best of our knowledge, this work is the first to assess ...
