Abstract:
The high vertical resolution and dense coverage of GPS data provide novel information on thermal structure and variability in the tropics, where short vertical scale features are common. This talk will highlight some recent work using GPS data to evaluate large- and small-scale temperature fluctuations in the tropics, and quantify links to large-scale circulation, extreme convection and stratospheric water vapor.
