          Abstract

          RESUMEN: Considerando los crecientes requerimientos de agua y energía en zonas áridas, se aborda la presencia del estratocúmulo costero como potencial recurso hídrico y el comportamiento de la radiación solar como fuente de energía. Este estudio exploratorio busca conocer las relaciones entre atenuación de la irradiancia por tipología de niebla (orográfica o advectiva) y la producción de agua de niebla asociada. Se analizó septiembre 2013 mediante imágenes satelitales GOES, datos del neblinómetro (SFC) y el radiómetro localizados en la Estación Atacama UC_Oasis Niebla Alto Patache (20° 49' S - 70° 09'O -800 m s.n.m.). Se encontró complementariedad entre los ciclos diarios de estos recursos y sus horarios productivos de agua y energía (noche y día) respectivamente. Esta investigación motiva estudios posteriores sobre agua de niebla y energía solar como recursos complementarios en línea con implementar tecnologías para tratamiento, manejo y distribución del agua, así como limpieza de paneles solares.

          ABSTRACT: Considering the increase of water and energy requirements in arid zones, this work combine the presence of the coastal stratocumulus as a potential water resource and the behavior of solar radiation as an energy source. The aim is to know the relationships between attenuation of irradiance by fog typology (orographic or advective) and the yields of associated fog water. September 2013 was analyzed using GOES satellite images, data from the Standard Fog Collector (SFC) and the radiometer located at the Atacama UC Station, Oasis de Niebla Alto Patache (20 ° 49 'S - 70 09'O -800 m a.s.l.). Results show complementarity between the daily cycles of these resources and their productive hours of water and energy (night and day) respectively. This research motivates subsequent studies on fog water and solar energy as complementary resources in line with implementing technologies for wáter treatment, management and distribution, as well as solar panel dust cleaning.

          Fog as a fresh-water resource: overview and perspectives.

          The collection of fog water is a simple and sustainable technology to obtain fresh water for afforestation, gardening, and as a drinking water source for human and animal consumption. In regions where fresh water is sparse and fog frequently occurs, it is feasible to set up a passive mesh system for fog water collection. The mesh is directly exposed to the atmosphere, and the foggy air is pushed through the mesh by the wind. Fog droplets are deposited on the mesh, combine to form larger droplets, and run down passing into a storage tank. Fog water collection rates vary dramatically from site to site but yearly averages from 3 to 10 l m(-2) of mesh per day are typical of operational projects. The scope of this article is to review fog collection projects worldwide, to analyze factors of success, and to evaluate the prospects of this technology.
