Dew Point Temperature at 2 m above the earth’s surface gives an indication of conditions which a person will experience or feel. High dewpoint temperatures inhibit heat loss from the body by perspriation and...

Temperatures at 2 m above the earth’s surface and winds at 10 m above the earth’s surface approximate most closely to the conditions that a person would experience.

The 850 hPa level is usually just above the boundary layer and at this level the day-night variation in temperature is generally negligible...
