Temporal scaling study of particulate matter (PM10) and solar radiation influences on air temperature in the Caribbean basin using a 3D joint multifractal analysis

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

“…To achieve this, the degree distribution P (k) of the VGs is analyzed. This quantity is defined as the number of nodes of Domínguez, 2020). In other words, hubs likeliness will be less significant than nodes close to P M 10 average.…”

“…These peaks can be caused by sporadic episodes of African dust transported by a particular circulation of air masses during Spring (Jury, 2017) or by extreme events as the eruption of Soufrière on Montserrat in February 2010 (Plocoste and Calif, 2019). This is the reason why they are called "high" and "low" seasons for African dust in literature (Prospero et al, 2014;Velasco-Merino et al, 2018;Plocoste and Pavón-Domínguez, 2020) because depending on the synoptic conditions, dust outbreak can occur between October and April.…”

“…the low dust season (October to April) and the high dust season (May to September) (Prospero et al, 2014;Plocoste and Pavón-Domínguez, 2020b). that the skewness and the gap between VG-UDVG gamma exponents values are lower.…”

“…In early 80s, multifractal analysis was firstly introduced by Mandelbrot (1982) in order to study the energy dissipation in the context of the fully developed turbulence with multiplicatives cascades models. Subsequently, this approach was widely used in environmental studies (Tessier et al, 1994;Seuront et al, 1996;Kravchenko et al, 1999;Lee, 2002;Jiménez-Hornero et al, 2011;Calif and Schmitt, 2014;Baranowski et al, 2015;Dong et al, 2017;Carmona-Cabezas et al, 2019a;Plocoste and Pavón-Domínguez, 2020b), to cite a few. Indeed, due to the possibility of having different densities depending on the region of application, multifractal analysis is regarded as the inherent property of complex and composite systems (Mandelbrot, 1974).…”

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

“…Epidemiological studies reveal that short-and long-term exposure to high concentrations of P M 2.5 and P M 10 can cause human health problems (Weinmayr et al, 2010;Atkinson et al, 2014;Lu et al, 2015). The authors focused on P M 10 , which also strongly impacts climate (Plocoste and Pavón-Domínguez, 2020b;.…”
