Figure 2

Radiosonde temperature profiles. Temperature profiles observed during daytime (dashed red line) and nighttime (solid blue line) radiosonde launches. Profile plots are shifted along the x-axis, in order to improve the figure readability; therefore, the x-axis only shows temperature increments of 10 K. The horizontal dash-dotted line indicates the minimum height threshold (300 m) used to exclude the inversion layer for the regression analysis.
