| Description |
Water vapour plays a dominant role in the high-energy thermodynamics of the atmosphere, notably, the genesis of
storm systems. However, its distribution is difficult to resolve by conventional means, since water vapour exhibits very
high spatial and temporal variability. The growing networks of continuously operating GPS systems, however, offer the
possibility of estimating the integrated water vapour (IWV) or, equivalently precipitable water vapour (PW). These
estimates constitute critical inputs in operational weather forecasting and fundamental research to model atmospheric
storm systems, atmospheric chemistry, and the hydrological cycle. This paper presents the results of IWV estimates
from GPS data from continuously operating GPS stations established by C-MMACS at Bangalore, Kodaikanal, Hanle
and Shillong over the 3-year period (2001–2003). These are the first results of such an endeavor, towards the study of
PW at four different geographical locations in the Indian subcontinent.
