Remote Sensing of water vapor and the Global Hydrological Cycle. Global Remote Sensing of Water Vapor and the Hydrological Cycle Background The water vapor remote sensing challenge What GPS RO offers Research Goals GPS RO moisture accuracy and information content Global water vapor climatology GPS and NWP global moisture comparison: Means and Biases Variability of water vapor and accuracy of global water analyses The tropical water vapor distribution and water vapor feedback GPS-derived Water Vapor and Clouds Background My interests lie largely in atmospheric water, the hydrological cycle and how water concentrations are controlled particularly the climatic feedbacks related to water.
Water is the most important greenhouse gas and small amounts of water in the form of clouds strongly affect both short wave and long wave radiation. The complex water-related interactions and feedbacks in our weather and climate system make such a task daunting but do not diminish its necessity.

A. ESRL Global Monitoring Division - CarbonTracker. CarbonTracker CT2013B CarbonTracker is a CO2 measurement and modeling system developed by NOAA to keep track of sources (emissions to the atmosphere) and sinks (removal from the atmosphere) of carbon dioxide around the world. CarbonTracker uses atmospheric CO2 observations from a host of collaborators and simulated atmospheric transport to estimate these surface fluxes of CO2.
The current release of CarbonTracker, CT2013B, provides global estimates of surface-atmosphere fluxes of CO2 from January 2000 through December 2012. CarbonTracker CO2 weather for June-July, 2008. Warm colors show high atmospheric CO2 concentrations, and cool colors show low concentrations. As the summer growing season takes hold, photosynthesis by forests and crops draws concentrations of CO2 down, opposing the general increase from fossil fuel burning. Executive Summary Estimates of CO2 sources and sinks over North America Figure 1. Spatial distribution of surface fluxes Figure 2. The CarbonTracker observing system.
