These highlights from the MISR Active Aerosol Plume-Height (AAP) Project  show smoke heights from the Bearnose Hill and Shovel Creek fires in Alaska on July 6th, 2019.
These images compiled by NASA’s Multi-angle Imaging SpectroRadiometer (MISR) Active Aerosol Plume-Height Project illustrate smoke heights from the Bearnose Hill and Shovel Creek fires in Alaska on July 6. MISR’s stereo texture and color images enable accurate mapping of wildfire smoke-plume heights, distinguishing smoke plumes from clouds based on detected particle properties. On July 6 and 8, MISR observed multiple fire plumes emanating from a wildfire outbreak across Alaska. Imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) on July 6 shows dense smoke from the...

Kahn / NASA GSFC Volcanic eruptions can generate significant amounts of atmospheric aerosols that often have regional to global impacts. To determine the influence of volcanic eruptions, accurate plume heights are needed, but are difficult to obtain  due to the hazardous nature of such eruptions. Stereo images from NASA’s Multi-Angle Imaging Spectroradiometer (MISR) make it possible to map plume heights...

MISR highlights June 23rd 2018
June 23rd, 2018 Volcanic eruptions can generate significant amounts of atmospheric aerosols that often have regional to global impacts. To determine the influence of volcanic eruptions, accurate plume heights are needed, but are difficult to obtain  due to the hazardous nature of such eruptions. Stereo images from NASA’s Multi-Angle Imaging Spectroradiometer (MISR) make it possible to map plume heights in ongoing eruptions using parallax in the stereo imagery. We can also...
