Figure 3 - Top Left - Plots of co-located ascending WVSS-II observations (colored) and rawinsonde data (black) taken around 0827 UTC on 30 April 2010 at Rockford IL. Temperature (C) at left, Specific Humidity (g/kg) at right, solid lines during descent, dashed lines during ascent. Changes between bounding rawinsondes shaded. Top Right - Differences between rawinsonde and ascending aircraft observations using same color convention as top panel. Shading indicates ±50% of hourly changes observed between bounding rawinsonde reports. Bottom Same as top panels, except for descending WVSS-II observations taken around 0310 UTC on 24 August 2010.
