We believe that the small changes in soil NO emissions are due to changes in the atmospheric concentrations associated with the air quantity moisture fixes since these NO emissions are dependent on NOy deposition. The small changes in lightning NO emissions appear to arise from the effects of air quantity moisture fixes on variables such as derived cloud top height that affect the lightning parametrization. |
