Global Water Vapor Trend from 1988 to 2011 and Its Diurnal Asymmetry Based on GPS, Radiosonde, and Microwave Satellite Measurements

  • Analyzes trends in precipitable water (PW) over land and ocean from 1988 to 2011
  • Finds that positive PW trends predominate over the globe, with larger magnitudes over ocean than over land
  • Finds that the PW trend is correlated with surface warming spatially over ocean
  • Finds that the PW percentage increase rate normalized by Ts expressed as is larger and closer to the rate implied by the Clausius–Clapeyron (C–C) equation over ocean than over land
