![]() ![]() The researchers also captured bursts of extremely intense solar radiation. Corderoīased on the first five years of data from the observatory, the average amount of solar power hitting each square meter of the landscape - 308 watts - is consistent with the earlier satellite observations and even higher than values recorded by a pyranometer near the summit of Mount Everest, the team reports. A researcher working high in the Andes Mountains of Chile sets up an instrument to measure solar radiation. Since 2016, the researchers have been measuring solar radiation levels at the site using a pyranometer, a palm-sized instrument sensitive to ultraviolet, visible and near-infrared light. To answer that question, Cordero and colleagues set up a small atmospheric observatory, housed in two shipping containers, in the Chilean Altiplano. But since satellites look down on our planet’s surface from afar, it’s important to verify that claim with on-the-ground data, says Raúl Cordero, a physicist at the University of Santiago in Chile. Satellite data have suggested that the Altiplano - a high-altitude plateau in the Atacama that straddles parts of Chile, Bolivia, Peru and Argentina - experiences the most intense levels of sunlight on Earth. ![]() It’s there that the sun’s rays on Earth are most intense, beating out places like Mount Everest and even, occasionally, rivaling the conditions on Venus, researchers report July 3 in the Bulletin of the American Meteorological Society. Forget Arizona or Florida - sun worshippers ought to head to the Atacama Desert in South America. ![]()
