Remote Sensing, as a driver for water management decisions, needs further integration with monitoring quality programs, especially in developing countries. Moreover, usage of remote sensing approaches has not been broadly applied routines. Therefore, it is necessary to assess the efficacy available sensors complement often limited field measurements from such programs and build models that support tasks. Here, we integrate (2013–2019) Mexican national system (RNMCA) data Landsat-8 OLI,...
ABSTRACT A significant proportion of the solar irradiance that reaches E arth's surface is normally attenuated by atmospheric properties and overcast conditions related to rainy season. The S olar nalyst ( SA ) model, long term precipitation data were used assess this relationship in G uadalajara, M exico. spatial analysis based on morphological statistical criteria increased model's certainty. model explains 95.4% irradiation variability observed ground, with average uncertainties 3.7%...
Herbicides have contributed to increased agricultural production. However, their residual amount can cause negative effects on environmental and public health. Therefore, this work aimed determine the occurrence of both atrazine diuron in surface well water investigate link with drinking use. The samples were collected during dry rainy seasons three wells from a river pond located low plains Ixcatepec catchment, at Amacuáhuitl community municipality Arcelia, Guerrero State, center south...
The city of Cuernavaca has experienced a significant deterioration in air quality recent years. Despite this situation, few studies the region have constantly monitored problem. objective study was to determine concentrations heavy metals PM2.5 three representative sites and estimate risks posed human health environment. results revealed following order abundance: Fe > Al Mg Zn As Ni V Pb Mn. EF indicated that comes mainly from anthropogenic emissions; Zn, V, Pb, come natural sources; Mn,...

This study was conducted from May 25 to June 6, 2009 at a downtown location (Centro) and an urban sector (Miravalle) site in the Metropolitan Zone of Guadalajara (MZG) Mexico. The atmospheric concentrations PM2.5 its elemental inorganic components were analyzed identify their potential sources during warm dry season. daily measurements (24 h) exceeded WHO (World Health Organization) air quality guidelines (25 μg·m−3). most abundant element found be Fe, accounting for 59.8% 72.2% total metals...
Polycyclic aromatic hydrocarbons (PAHs) and quinones in the gas phase as submicron particles raise concerns due to their potentially carcinogenic mutagenic properties. The majority of existing studies have investigated formation quinones, but it is also important consider both primary secondary sources estimate contributions. objectives this study were characterize PAHs particulate matter (PM1) phases order identify distributions, sources, cancer risk at two urban monitoring sites...
Previous studies, based on limited data, found elevated levels of mercury in carp Lake Chapala, Mexico. The extent contamination throughout the has not been determined. In order to obtain reliable information about total concentration (Cyprinus carpio), 262 fish from 27 sites (approximately 10 per site) lake were analyzed. Results expressed as mean and median results at each site. Only one samples exceeded Mexican National Standard (1.0 ppm) for flesh. We discuss these comparison World...
This study aims to establish the influence of primary emission sources and atmospheric transformation process contributing concentrations quinones associated particulate matter less than 2.5 µm (PM2.5) in three sites within Metropolitan Area Guadalajara (MAG), namely Centro (CEN), Tlaquepaque (TLA) Las Águilas (AGU). Environmental levels extracted from PM2.5 filters were analyzed using Gas Chromatography coupled Mass Spectrometry (GC-MS). Overall, emissions combination with photochemical...
Tropospheric ozone is an obligatorily-regulated pollutant, to ensure health protection and better air quality. Most countries have established maximum permissible limits (MPL) equal 0.06 or 0.070 ppmv, but these could be insufficient considering the strictest MPL of World Health Organization (WHO) guidelines. Such concentrations may still cause damage some groups population in urban areas. Additionally, mean value principal statistical parameter for monitoring pollution. This factor hiding...
The spatial assessments of water supply quality from wells, springs, and surface bodies were performed during the dry rainy seasons in six municipalities eastern regions Michoacán (Central Mexico). Different physicochemical parameters used to determine supplies’ Water Quality Index (WQI); all communities presented good quality. analysis indicates that many within limits set by international standards, showing levels “excellent quality” according WQI, mainly season (except at San Pedro...
Los estudios relacionados con los cambios progresivos en la cobertura vegetal y de uso suelo, han cobrado importancia investigación ambiental, ya que permitido evaluar las tendencias espacio-temporales procesos como deforestación degradación provocadas por actividades humanas. En este contexto, el objetivo estudio fue impacto antropogénicas cuenca del río Tecolutla, Veracruz, México; un periodo 16 años. Se utilizaron imágenes satélite Landsat para años 1994 2010, distinguiéndose nueve usos...
Temporal delays and spatial randomness between ground-based data satellite overpass involve important deviations the empirical model output real data; these are factors poorly considered in calibration. The inorganic matter-generated turbidity Lake Chapala (Mexico) was taken as a study case to expose influence of such factors. Ground-based from this historical records were used references. We take advantage at-surface reflectance Landsat-8, sun-glint corrections, reduced NIR-band range, null...

Nitrogen dioxide (NO2) is a critical air pollutant that has significant health and environmental impacts. Tropospheric NO2 refers specifically to the vertical column density of NO2, which measured by satellites serves as an indicator anthropogenic sources. This frequently assessed using satellite data owing limitations in local monitoring. investigation employs Spectral Angle Mapper (SAM), geometric machine-learning model, given its advantages simplicity computational efficiency, OMI...
The diel variation of meteorological conditions strongly influences the formation processes secondary air pollutants. However, due to complexity sampling highly reactive chemical compounds, significant information about their transformation and source can be lost when over long periods, affecting representativeness samples. In order determine contribution primary sources ambient levels polyaromatic hydrocarbons (PAHs) quinones, measurements gas PM1 phases were conducted at an urban site in...
