Evapotranspiration issue

Post by mcrossley »

At 00:46 1/Jan/14 --> Evapotranspiration today = -410.54 mm

Which doesn't seem quite right. :) I'm used to seeing values such as -0.03 mm after midnight, but the year end roll over seems to have gone wrong.

Cumulus b1086, VP2 f/ware 3.12.

The console show's ET values of zero. Still the same at 8:30.

PS: Happy New Year.

It's for reasons similar to the fact that the 'last 24 hours' rain doesn't work on the 1st Jan with Davis stations.

Ah, yes stands to reason. I just stopped Cumulus, changed the start of day ET value to zero in today.ini and restarted Cumulus - the ET value looks OK now.
