Use of the Cathode Ray Oscillograph for Studying the Near Infra-Red Solar Spectrum

Nature volume 160, pages 130131 (26 July 1947) | Download Citation



An apparatus has been developed in the Radiation Laboratory of the Meteorological Office at Poona for the measurement of absorption due to atmospheric water vapour in the near infra-red region of the solar spectrum by means of a cathode ray oscillograph. The working principle of this apparatus and the object for which it was developed are entirely different from those described by Daly and Sutherland and by King, Temple and Thompson1, and it was developed independently of their work. A short paper describing it was read by me at the symposium on “Atmospheric Processes” held at the Royal Institute of Science, Bombay, under the auspices of the National Institute of Sciences of India in August 1946. This paper is at present in course of publication in a special issue of the Transactions of the National Institute of Sciences of India.
