Atmospheric water vapour plays an important role in radio communication for both terrestrial and earth space communication systems as well as for global climate change studies and weather forecasting. Consequently the water vapour datasets usage and the method of data computation are the key factors in evaluation of atmospheric water vapour trends and usage. Since from few decades there are many studies conducted in India, however there are some variations in water vapour observational data analysis techniques and computation of the results while comparing with earlier work with very recent years; that's may be because of earlier period there was limited observational or theoretical understanding with the available resources on water vapour data and its validation and finally the implications of the results. In recent years, the technology and resources have improved tremendously.
The present paper presents the recent results deduced by using modern computational techniques on water vapour distribution for various Indian regions. In general Radiosonde observations are the primary source of upper air water vapour data and are being used for estimation of different atmospheric parameters. As a part of this study, radiosonde observations over 44 Indian stations pertaining to a period of 15 years from 1996 to 2011 obtained from the British Atmospheric Data Centre are integrated and analysed from the different met parameters of air temperature, dew point temperature and pressure levels for water vapour concentrations estimation at different height (pressure levels). The datasets integration has been carried out by using modern data warehousing techniques and applied better reporting analytics for precise results. The observational results of water vapour distribution patterns and trends are presented in the form of regional, annual and seasonal charts for better decision supporting systems. In fact it is an improved version of the detailed studies related to water vapour concentration over India.
