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). ... -
Joint multifractal analysis of air temperature, relative humidity and reference evapotranspiration in the middle zone of the Guadalquivir river valley
Ariza Villaverde, Ana Belén; Pavón Domínguez, Pablo; Carmona-Cabezas, Rafael; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2019)Previous works have analysed the relationship existing between reference evapotranspiration (ET0) and other climatic variables under a one-at-a-time perturbation condition. However, due to the physical relationships between ... -
Multifractal detrended fluctuation analysis of sheep livestock prices in origin
Pavón Domínguez, Pablo; Serrano, Salud; Jiménez-Hornero, Francisco José; Jiménez Hornero, Jorge; Gutiérrez de Ravé Agüera, Eduardo; Ariza Villaverde, Ana Belén (Elsevier, 2013)The multifractal detrended fluctuation analysis (MF-DFA) is used to verify whether or not the returns of time series of prices paid to farmers in original markets can be described by the multifractal approach. By way of ... -
Multifractal detrended fluctuation analysis of temperature in Spain (1960–2019)
Gómez-Gómez, Javier; Carmona-Cabezas, Rafael; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2021)In the last decades, an ever-growing number of studies are focusing on the extreme weather conditions related to the climate change. Some of them are based on multifractal approaches, such as the Multifractal Detrended ... -
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 ... -
Relationships between Reference Evapotranspiration and Meteorological Variables in the Middle Zone of the Guadalquivir River Valley Explained by Multifractal Detrended Cross-Correlation Analysis
Gómez-Gómez, Javier; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (MDPI, 2023)The multifractal relationship between reference evapotranspiration (ET0), computed by the Penmann-Monteith equation (PM), relative humidity (RH) and mean surface temperature (Tmean) was studied in the middle zone of the ... -
Visibility graphs of ground-level ozone time series: A multifractal analysis
Carmona-Cabezas, Rafael; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2019)A recent method based on the concurrence of complex networks and multifractal analyses is applied for the first time to explore ground-level ozone behavior. Ozone time series are converted into complex networks for their ...
