A ground-based solar infrared spectro-radiometer was used for the measurement of atmospheric minor constituents over Delhi(28.7 degree N, 77.2 degree E and 220 meter MSL) during the solar eclipse of 1995. A decrease in water vapour and an increase in the aerosol optical depth were observed during the solar eclipse. An increase in solar irradiance was also evident in the wavelength range of 1200 nm to 1700 nm.
