Abstract:
The occurrence of Total Solar Eclipse on October 24, 1995 provided an unique opportunity to conduct some experiments using IR sun photometers in the spectral range 0.75 micrometer to 1.6 micrometer and 205 to 14.5 micrometer during eclipse at Nim Ka Thana (27 degree 47'N, 75 degree 47' E) and New Delhi(28 degree 39' N, 77 degree 13' E) respectively. The measurements have been used to estimate the amount of water vapour, ozone etc. A significant variation in IR solar irradiance at various window wavelengths during the solar eclipse was observed. Also measurements of temperature and humidity were made on regular interval from 22nd to 26th October 1995. In the present paper the experimental set up and results obtained are discussed.
