| Abstract: | An attempt has been made to estimate the photolysis frequency of O1D in troposphere and stratosphere of the Indian region. The radiation code Lowtran 7 is used to estimate actinic flux at these altitudes. An accurate and efficient multiple scattering parametrization along with k-distribution method has been used in this model. For ozone, observed averaged profile for the year 1976 as well as 1994 is used for Delhi, Pune and Thiruvananthapuram. Values as recommended by DeMore et al. [JPL Publication, 1994, p.94] and Michelsen et al. [Geophys Res Lett (USA). 21 (1994) 2227.] have been taken for ozone quantum yield. The values of photolysis frequency of O1D are found to be significantly higher for the quantum yield given by Michelsen et al. A decrease in these values is also observed in the year 1994 as compared to that in preceding years up to 1976. |
