Today’s Image of the Day from NASA Earth Observatory features a smoky steppe fire in eastern Mongolia.
“When spring warmth melts snow off the steppe of eastern Mongolia, the remains of last year’s plant growth are exposed. In dry and windy conditions, these brown, withered grasslands can become tinder for wildfires,” reports NASA.
