Evaptranspiration Today
How is ET Today calculated? Is it a average of multiple calculations over a 24 hour period. How exactly is it calculated.

Re: Evaptranspiration Today
Cumulus does it in the same way as it does rainfall. It gets the annual total from the station periodically, and subtracts the value saved at midnight from the current reading. I can't tell you how the station calculates the figure.
