Ash Plume from Puyehue-Cordón Caulle [image] #NASA

On June 4, 2011, Puyehue-Cordón Caulle in Chile experienced its first major eruption in decades. The volcano sent an ash plume eastward, disrupting air traffic, threatening water supplies, and even dropping golf ball-sized pumice on parts of Argentina. From the start, the volcanic plume towered over local clouds. The top image is a nighttime scene acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. This false-color image is made from observations of infrared light. The image is rotated and north is at right. Running across the MODIS image is a yellow line that corresponds to the vertical profile of the atmosphere shown in the graph below. The atmospheric profile was acquired by Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO), a joint mission between NASA and the French Centre National d’Etudes Spatial...
