Mt Agung (Bali) Eruption Plumes

Mt Agung (Bali) eruption plumes seen by MISR November 29, 2017   Volcanic eruptions can generate a significant amount of atmospheric aerosols that have regional to global impacts. Accurate plume heights are needed to determine the influence of volcanic eruptions, but are difficult to obtain due to the hazardous nature of eruptions. Stereo images from NASA’s Multi-Angle Imaging Spectroradiometer (MISR) make it possible to retrieve plume heights during eruptions.

MISR glimpses Irma 3D imagery

View Larger Image

 

On Sept. 7, the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite passed over Hurricane Irma at approximately 11:20 am local time. The MISR instrument comprises nine cameras that view the Earth at different angles, and since it takes roughly seven minutes for all nine cameras to capture the same location, the motion of the clouds between images allows scientists to calculate the wind speed at the cloud tops.

This stereo anaglyph combines two of the MISR angles to show a three-dimensional view of Irma. You will need red-blue glasses to view the anaglyph; place the red lens over your left eye.
