Bivar.ate Analysis of Pollutants Monthly Maxima in Mexico City Using Extr.me Value Distr.butions and Copula

Jour.al of Envir.nmental Pr.tection 2024年第7期15卷 796-826页

作者： Juan A. Vazquez-Mor.les eliane r. rodrigues Hor.ensia J. r.yes-Cer.antes Facultad de Ciencias Fsico-Matemticas Benemrita Universidad Autnoma de Puebla Puebla Mexico Instituto de Matemticas Universidad Nacional Autnoma de Mxico Mexico City Mexico

In the pr.sent wor., we ar. inter.sted in studying the joint distr.butions of pair. of the monthly maxima of the pollutants used by the envir.nmental author.ties in Mexico City to classify the air.quality in the metr.politan ar.a. In or.er.to obtain the joint distr.butions a copula will be consider.d. Since we ar. analyzing the monthly maxima, the extr.me value distr.butions of Weibull and Fr.chet ar. taken into account. Using these two distr.butions as mar.inal distr.butions in the copula a Bayesian infer.nce was made in or.er.to estimate the par.meter. of both distr.butions and also the association par.meter. appear.ng in the copula model. The pollutants taken into account ar. ozone, nitr.gen dioxide, sulphur.dioxide, car.on monoxide, and par.iculate matter.with diameter. smaller.than 10 and 2.5 micr.ns obtained fr.m the Mexico City monitor.ng networ.. The estimation was per.or.ed by taking samples of the par.meter. gener.ted thr.ugh a Mar.ov chain Monte Car.o algor.thm implemented using the softwar. OpenBugs. Once the algor.thm is implemented it is applied to the pair. of pollutants wher. one of the coor.inates of the pair.is ozone and the other.var.es on the set of the r.maining pollutants. Depending on the pollutant and the r.gion wher. they wer. collected, differ.nt r.sults wer. obtained. Hence, in some cases we have that the best model is that wher. we have a Fr.chet distr.bution as the mar.inal distr.bution for.the measur.ments of both pollutants and in other. the most suitable model is the one assuming a Fr.chet for.ozone and a Weibull for.the other.pollutant. r.sults show that, in the pr.sent case, the estimated association par.meter.is a good r.pr.sentation to the cor.elation par.meter. between the pair.of pollutants analyzed. Additionally, it is a str.ightfor.ar. task to obtain these cor.elation par.meter. fr.m the cor.esponding association par.meter..

Jour.al of Envir.nmental Pr.tection 2016年第12期7卷 1886-1903页

作者： Juan Antonio Cr.z-Juár.z Hor.ensia r.yes-Cer.antes eliane r. rodrigues Facultad de Ciencias Fisico-Matemáticas Benemérita Universidad Autónoma de Puebla Puebla Mexico Instituto de Matemáticas Universidad Nacional Autónoma de México Mexico City Mexico

In this wor., some non-homogeneous Poisson models ar. consider.d to study the behaviour.of ozone in the city of Puebla, Mexico. Sever.l functions ar. used as the r.te function for.the non-homogeneous Poisson pr.cess. In addition to their.dependence on time, these r.te functions also depend on some par.meter. that need to be estimated. In or.er.to estimate them, a Bayesian appr.ach will be taken. The expr.ssions for.the distr.butions of the par.meter. involved in the models ar. ver. complex. Ther.for., Mar.ov chain Monte Car.o algor.thms ar. used to estimate them. The methodology is applied to the ozone data fr.m the city of Puebla, Mexico.

A Gibbs Sampling Algor.thm to Estimate the Par.meter. of a Volatility Model: An Application to Ozone Data

In this wor. we consider.a stochastic volatility model, commonly used in financial time ser.es studies, to analyse ozone data. The model consider.d depends on some par.meter. and in or.er.to estimate them a Mar.ov chain Monte Car.o algor.thm is pr.posed. The algor.thm consider.d her. is the so-called Gibbs sampling algor.thm which is pr.gr.mmed using the language r. Its code is also given. The model and the algor.thm ar. applied to the weekly ozone aver.ged measur.ments obtained fr.m the monitor.ng networ. of Mexico City.

A nonhomogeneous Mar.ov chain is applied to the study of the air.quality classification in Mexico City when the so-called cr.ter.on pollutants ar. used. We consider.the indices associated with air.quality using two r.gulations wher. differ.nt ways of classification ar. taken into account. Par.meter. of the model ar. the initial and tr.nsition pr.babilities of the chain. They ar. estimated under.the Bayesian point of view thr.ugh samples gener.ted dir.ctly fr.m the cor.esponding poster.or.distr.butions. Using the estimated par.meter., the pr.bability of having an air.quality index in a given hour.of the day is obtained.

Appr.ach for.C1 to C2 pr.ducts commencing fr.m car.on dioxide: A br.ef r.view

The car.on dioxide (CO2) conver.ion to useable compounds r.mains a gr.at contest to scientists, engineer., and envir.nmentalists with r.gar. to the r.ver.e of the oxidative degr.dation of or.anics. This conver.ion is essential for.the development of complementar. fuels and r.w mater.als for.var.ous industr.es, which in tur. will help in avoiding the dr.stic incr.ase in tr.pospher.c temper.tur. due to gr.enhouse effect leading to global war.ing. The solar.ener.y is the ear.h's essential power.sour.e along with the other.var.ous for.s of ener.y for.example fossil fuels, hydr.power. wind, and biomater.als, etc. The final goal is to establish the ar.ificial photosynthesis, which can be r.plicated thr. var.ous chemical r.duction techniques of CO2 by employing appr.pr.ate photo-, ther.al- and electr.-catalysts in or.er.to pr.duce differ.nt one car.on atom (C-1) and higher.car.on atoms containing pr.ducts. Besides, the utilization of clean and sustainable CO2 towar.s high-value pr.ducts is of gr.at inter.st today due to the r.cognized envir.nmental wor.ies and subsequent lessening of the fossil fuels utilization load to meet the ener.y demand of mankind. This way, solar.ener.y can dir.ctly and/or.indir.ctly be alter.d and stor.d in chemical ener.y for. for.industr.al as well as societal applications. In this ar.icle our.endeavor.is to summar.ze the advances in CO2 chemical r.duction r.sear.h ar.a till date especially in fr.e r.dical-based methods such as electr.chemical, photochemical and plasma chemical for.the development of car.on species up to two car.on (C-2) atoms containing pr.ducts per.eived in the chemical r.duction of CO2. The author.hopes that this piece of wor. will be helpful to r.sear.her. and r.ader. who ar. focused on the field of CO2.
