Air frost
« on: March 20, 2012, 06:22:45 AM »
Hi

can someone please tell me what the formula is for calculating whether there has been an air frost overnight.

Would this formula give ground frost as well?

John,

Air frost occurs when the air temp is < 32F.

It's that simple?  #-o

I imagined a long formula with loads of "divide by the number you first thought of" things  :roll:
