Abstract:
From a series of photoelectric scanner observations during 1980-85, the atmospheric extinction at Kavalur has been analysed. The variation of this appears to follow lamda/sup-4/ law. There is a general increase in the aerosol absorption during 1980-85. An attempt made to compare the meterological data on ozone and water vapour measures, shows that the absorption due to ozone was marginally higher during 1980-81. The absorption due to water vapour appears to be varying during the night, making such comparisons very difficult
