The dew point temperature and relative humidity values are commonly used to express the humidity levels present in our atmosphere. So why does the featured chart display this value in terms of mixing ratio? Mixing ratio is an absolute measure of humidity as it compares the mass of water vs the mass of the dry air holding the water and can be directly compared with mixing ratio values at other times of the year. On average, mixing ratio values are 3 times larger in mid July than currently for the end of March.
