Brief Description (Abstract):

The solar radiation at five wavelengths 300 nm, 305 nm 312nm, 940 nm and 1020 nm using narror band (2.5 nm FWHM) filters has been measured using a microprocessor based sun photometer from Jan. 1997 to Feb. 1998 on hourly basis on all clear days at Maitri during Sixteenth Indian Scientific Antarctic expedition. The total column ozone has been estimated from these measurements. Very low ozone values have been observed during Antarctic spring, which confirmed the continuity of ozone hole phenomenon. It has also been found that ozone values are high during Antarctic summer while low during spring.

Status: Completed

Purpose: Ozone in the stratosphere is very important for the survival of life on the earth as it protects us from harmful ultraviolet radiation coming from the sun. Ozone in the troposphere also acts as a greenhouse gas, trapping the long wave radiation and thus affecting the energy budget of the earth-atmospheric system. The reporting of ozone hole in particular by Farman et al. (1985) and ozone depletion in general by Johnston et. al. (1971) has generated an unprecedented surge of interest in the scientific community in monitoring of ozone in the atmosphere. The chloro-fioro carbons are the main culprits of ozone depletion in the stratosphere and ozone hole phenomenon over Antarctica.
