Fire Band

Caption

A dark blue band spanning north equatorial Africa shows where November-February density of polluting airborne nitrogen oxides have been declining. (Lighter blue areas to the south show lesser declines, but these are due more to to phaseouts of coal-burning power plants.) Yellow and red areas show increases in nitrogen oxides.
