[CAUT] FW: Temperature/Humidity range

[Craig_Waldrop]

Chris,
Absolute humidity?  Why, that's when it's too darn hot to go outside.  I'm
sure someone explained when you attended the TSA regional in Austin that
"It's not the heat it's the humidity!"

Okay, bad joke.

1.  Absolute Humidity = mass of water vapor/ volume of air

2.The ratio of the mass of water vapor to the volume occupied by a mixture
of water vapor and dry air or

3.  mass of water contained in a unit volume of moist air
