Plot Description:

Simple plot of yearly average dew points by year, season, or month. This calculation was done by computing the mixing ratio, then averaging the mixing ratios by year, and then converting that average to a dew point. This was done due to the non-linear nature of dew point when expressed in units of temperature.

Based on a sampling of recent timings for this application, plot generation time has averaged 17 seconds. Hold on for the plot is generating now!
