Abstract:
In this work, according to FY-3 observations (measurements of Total Ozone Unit (TOU), Solar Backscatter Ultraviolet Sounder (SBUS) and Space Environment Monitor (SEM)), we analyze polar ozone depletions with Solar Proton Events (SPE) which occurred in late January and early March. Ozone distributions change with increasing energetic proton flux (particle energy is over 100MeV) at altitude of 30km. Total ozone content reduces 4%-5% during February in high latitude regions of both hemispheres that the ozone depletions contain season variations and SPE effects. From ozone profile anomaly analyses, the short-term effects of SPE can be distinguished from long-term effects of ozone season variations after SPEs took place. At the upper stratosphere, the SPE-related ozone depletions are more significant in the Northern Hemisphere in January and the short-term effects are more pronounced in March in the Southern Hemisphere.
