Mesospheric ozone variation associated with the solar proton events of August and October 1989
Abstract. The EISCAT radar measurements of N e electron density during the proton events of 13 August and 23 October 1989 have been analyzed. It has been established that the form of sunset variation of the electron density observed during the two events is sufficiently different. The calculation of...

| Summary: | Abstract. The EISCAT radar measurements of N e electron density during the proton events of 13 August and 23 October 1989 have been analyzed. It has been established that the form of sunset variation of the electron density observed during the two events is sufficiently different. The calculation of N e variation has been carried out using the ion chemistry model and measured proton fluxes. The interpretation of the observed N e variations has been made by comparing calculation and measurement results The conclusion has been made that at the mesospheric altitudes, the ozone concentration was much smaller in the event of 23 October 1989 than the one on the event of 23 October 1989. |
