Abstract

A theoretical investigation has been made into the variation of the ozone concentration in the atmosphere which results from an eclipse of the sun. The variation of the ozone concentration with time was followed by numerically integrating the relevant differential equations, allowing for the change in the solar radiation intensity reaching the earth's atmosphere during the eclipse. The results show that an increase of only 0.6 % occurs in the total ozone amount, and that the eclipse does not affect the ozonosphere below 45 km. The theoretical results are compared with experimental observations and reasons are advanced for the discrepancy between the two, which indicate that better agreement should be obtained when corrections for limb darkening of the sun are incorporated in the analysis of the experimental results.
