It is shown that equations describing chemical partitioning among Clx(HCl, Cl, ClO, ClNO3), NOt(NO, NO2, NO3, N2O5, HNO2, CNO3) and HOx (OH, HO2) may admit multiple solutions. These solutions apply to the high latitude winter stratosphere where abrupt spatial variations may be expected for NO2, ClO and ClNO3. |
