Comments	"High temperatures occurring in lightning strikes produce NO in the atmosphere from molecular oxygen and nitrogen. Subsequently this NO is oxidized to NO2 and then to HNO3 and quickly (i.e., days) removed by wet and dry deposition thus introducing Nr into ecosystems primarily over tropical continents. Most current estimates of Nr creation by lightning range between 3 and 10 Tg N/yr (primary source)."
