NASA shared a picture showing “river of smoke” over Delhi and nearby areas on November 11 due to crop fires. “I would say that a conservative estimate is that at least 22 million people were affected by smoke on this one day,” a NASA scientist said. Fires in northern Pakistan likely contributed some of the smoke as well, NASA said.
