Effect of stellar scintillations on the errors in measuring the ozone content of the atmosphere

Methods and algorithms are developed for the numerical simulation of stella r scintillations in the atmosphere during satellite observations. Estimates of the accuracy of remote measurements of the ozone content in the atmosph ere are obtained on the basis of the data on stellar radiation observed fro m space with allowance made for scintillations under different observation conditions. The dependence of the measurement accuracy on the spectral corr elations of scintillations is studied. It is shown that a noticeable increa se of errors in determining the ozone content is due to stellar scintillati ons and may reach, at least, a few percent. Such an increase is out of the limits of errors allowable nowadays in determining the gas content of the a tmosphere. The methods of the numerical simulation of stellar scintillation s and their consideration in determining the gas content from the results o f satellite measurements of the atmospheric transparency require further de velopment.
