Abstract: Integrated water vapour content over the northern regions of India has been found from the radiosonde data made available by India Meteorological Department from the three stations namely, New Delhi, Jodhpur and Srinagar. Water vapour content at various height columns and the yearly variations for the total content have been found for these stations. Correlations of the water vapour content and the refractivity variations for these three stations have been worked out. An intecomparison is also made of the integrated water vapour content by radiosonde data for New Delhi and that obtained by radiometer set up at the National Physical Laboratory, New Delhi, at 22.235 GHz by analyzing data for 1-½yr. The values found by radiometer observations are seen to be higher than those computed by radiosonde measurements. An attempt has been made to explain this difference.
