Study on the Impacts of Solar Proton Events on Middle Atmospheric Chemical Constituents on the high latitudes

Ion pair production rate data from real events of medium protons ( 20041108) were selected for separate simulation of proton events based on MERRA data run for one month close to the real atmospheric conditions at 2005.10.20 under the condition of serene background field and imported into the ion production rate data.Based on WACCM-SD model, the data shows the relative changes of response distributions of nitrogen oxides (NOx=N+NO+NO2), hydrogen oxides (HOx=H+OH+HO2), ozone (O3) during intense, moderate, and weak solar proton events at high latitudes（60-90°N，60-90°S) during ten days from the start of solar proton events to the end.
