[Comment on “GEWEX: The Global Energy and Water Cycle Experiment”] More global water balance uncertainty

Authors


Abstract

I concur strongly with Chahine's January 14, 1992, Eos article on GEWEX and support his response to Dincer's letter (Eos, June 16, 1992) emphasizing that “our quantitative knowledge of the hydrological cycle remains surprisingly poor.” This is despite the magnificent report on the world water balance to which Dincer refers and his allusion that the existence of a low residual in closing the water balance indicates low errors of measurement of the global budget components.
