RELATIVE HUMIDITY

Relative Humidity Vertical Profiles

Vertical profiles of the relative humidity are computed in the [0-20km] range above ground level (a.g.l.) and centered on the LBT. Data points frequency is 2 minutes.

TEMPORAL EVOLUTION:

The contour plot represents the temporal evolution of relative humidity vertical profiles between the sunset and the sunrise. On the x-axis is time in UT (bottom), in MST (top). Mountain Standard Time MST=UT-7. On the y-axis the height above ground level. The color scale represents the relative humidity percentage.

Fig. 1: Relative humidity vertical profile temporal evolution between the sunset and the sunrise. Dashed lines indicate the dusk and the dawn.

TIME AVERAGES:

Three time averages are presented, computed in the first, central and last part of the night (see partition). The corresponding MST (MST=UT-7) is shown on the top of the figure.
The blue light halo around each average represents the +/- sigma in the respective time window.
Fig. 5 represents the three time averages in the same plot with different colors to better appreciate the macroscopic changes in the three temporal intervals.
