Abstract :
The troposphere is subject to short term change resulting from radiation, convection, and advection. Weather forecasts based on radiosondes are sensitive to local changes that occur between the radiosonde soundings. Continuous thermodynamic and wind soundings can "fill the gaps" between radiosonde soundings, providing improved local weather forecasting. By including slant observations from a GPS network, local forecast improvements can be extended to regional scales. Radiometric observations including supercooled fog, boundary layer turbulence, summer monsoon and snowfall conditions are presented. Applications include sever storm forecasting, airport weather, urban pollution, and atmospheric dispersion.
