a With CO emission (top) and \({\nabla ({{{\bf{u}}}}\cdot {V}_{{CO}})}\) (bottom) from December to January. b With CO emission (top) and \({\nabla ({{{\bf{u}}}}\cdot {V}_{{CO}})}\) (bottom) in May. Red regions signify net sources due to transport and blue regions indicates the area for pollutant input.
