Plot Description:

This plot displays the average dew point at a given air temperature along with the envelope between the 5th and 95th percentile. The average dew point is computed by taking the observations of mixing ratio, averaging those, and then back computing the dew point temperature. With that averaged dew point temperature a relative humidity value is computed.
