NASA | NPP Sees Aftermath of the Chelyabinsk Meteor

A meteor exploded over Chelyabinsk, releasing debris into the atmosphere. The OMPS satellite observed the plume, which was modeled by NASA to predict its trajectory. The plume circumnavigated the globe, forming a belt, and persisted for a long time. These observations help in understanding atmospheric impacts and are crucial for climate and ozone studies.

What did the OMPS instrument on the Sumi MPP satellite observe after the explosion?

What was the significance of the satellite observations in relation to the plume's trajectory?
