The spatiotemporal evolution of the atmospheric boundary layer (ABL), in a narrow, highly complex terrain located Colombian Andes, is studied using radiosondes and remote‐sensing equipment. Different techniques are implemented to automatically estimate ABL height ceilometer backscattering profiles combination radar wind profiler microwave radiometer retrievals. large aerosol load from anthropogenic emissions within valley allows use ceilometer‐based detection methods, especially under stable...
Guatemala City is exposed to climate hazards, including landslides, flooding, heat islands, and drought. The territory also faces other significant vulnerabilities resulting from historical environmental mismanagement, inequality, urban structure, as well demographic factors. In this context, nature-based solutions (NBS) may provide multiple benefits, furthering the city’s sustainable development promoting its resilience. Drawing on case of perspectives local policymakers, we explore how...
The extensive use of fireworks generates large amounts pollutants, deteriorating air quality and potentially causing adverse health impacts. In Medellín its metropolitan area, although are banned during December, their is widespread the Christmas season, particularly midnight November 30 (La Alborada) New Year's Eve (NYE). It therefore essential to assess effects these celebrations on in region. Air-quality data from official monitoring network a low-cost particulate matter (PM) citizen...
Abstract. Flash floods are a recurrent hazard for many developing Latin American regions due to their complex mountainous terrain and the rainfall characteristics in tropics. These often lack timely high-quality information needed assess, real time, threats vulnerable communities extreme hydrometeorological events. The systematic assessment of past events allows us improve our prediction capabilities flash floods. In May 2015, flood La Liboriana basin, municipality Salgar, Colombia, caused...
Abstract Precipitation modulates the pollutant concentration in atmosphere directly and indirectly through different mechanisms. Wet deposition, including in-cloud scavenging below-cloud scavenging, is one of main drivers particulate matter removal from atmosphere. Our focus to assess net effect precipitation on using observations, a nonparametric conditional analysis, signed overlapping coefficient complement index. The study considers not only direct near-surface aerosol but also indirect...
El desierto del Sahara es una de las principales fuentes material particulado (MP) en el mundo. Este MP tiene la capacidad afectar calidad aire a miles kilómetros fuente. Las intrusiones este polvo Caribe están bien documentadas, sin embargo, no se han reportado contaminante grandes ciudades colombianas. En artículo analiza y determina posible relación entre emisiones un episodio alta contaminación que registró Bogotá Medellín finales junio 2014. Se utilizaron los datos registrados por redes...
<p>En Bogotá, estudios previos han mostrado que las emisiones de material resuspendido constituyen una parte sustancial del inventario e impactan manera importante la calidad aire ciudad. Esta investigación estimó los factores emisión (FE) particulado antes, durante y después pavimentación vía principal barrio Caracolí, en localidad Ciudad Bolívar, por Unidad Mantenimiento Vial Distrito (UMV). Conjuntamente, se midió el impacto aire. La valoración estimación experimental FE polvo...

&lt;p&gt;The heterogeneity of the urban features, in addition to inherent challenges added by highly complex terrain, has not allowed scientific community reach a complete understanding Atmospheric Boundary Layer (ABL) dynamics regarding land-atmosphere interactions. The intricacies are higher when trying simulate observed interactions and their implications for air quality numerical modeling...
