Abstract
The success of the implementation of the Montreal Protocol in India and its impact on the observed trend in total and stratospheric ozone at different Indian latitude belts have been examined using satellite data. Although the effective enforcement of the Montreal Protocol can be monitored through satellite data, it is difficult to attribute the observed slow-down in stratospheric ozone depletion entirely to the success of the Montreal Protocol, as a large number of natural and anthropogenic factors also influence the appropriate stratospheric ozone chemistry.
