Chile is home to a location where solar irradiance, the measure of solar energy striking the earths surface, matches that on Venus.The Chajnantor plateau, a broad, open site that houses numerous astronomical observatories, holds the record for the highest solar irradiance ever documented.Positioned 5,000 meters above sea level and 40 kilometers east of San Pedro de Atacama in the Antofagasta region of Chile, this location experiences sunlight similar to that received by the International Space Station, orbiting the Earth at an approximate distance of 400 kilometers.A team of scientists from the University of Santiago, led by climatologist Ral Cordero, has been monitoring these characteristics on the elevated plateau of the Atacama Desert since 2016.Chajnantor plateau.

Its akin to a magnifying glass effect instigated by the clouds.The plateaus radiation peaks occur during summer solstices and when snowfall descends in the altiplano winter, rendering the surface brighter than typical conditions.This studys results, involving researchers from the Universities of Groningen in the Netherlands, Arizona, and Stanford in the United States , were published in the Bulletin of the American Meteorological Society, a leading global meteorological publication.The study determined that the extreme radiation levels witnessed at Chajnantor are unrivaled worldwide, and the gathered data renders this location ideal for examining the safety, resilience, and design of future photovoltaic power plants resilient to fluctuation.Chile news, English news Chile, climate news Chile, Record-breaking solar radiation observed in Chile, solar energy striking Chiles surface matches that on Venus
