Solar Radiation

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

Solar Radiation

Post by Mapantz »

Hello!

I've just installed the Solar rad sensor for the VP2 and wondered about the evapotranspiration reading..
The console reads 0.38mm for daily/monthly/yearly - MX uploads the figure of 4.01mm. I'm a bit confused!

If you just installed it today, I'd see what happens tomorrow. The ET readings have always been a bit 'flakey'.

FWIW, My console vs. MX has

Code: Select all

        Con    MX
Today   0.3   0.4
Month  24.4  24.4
Year   61.7  61.9

Is MX calculating its own ET then?

The console is at 00.8mm and MX is at 1.02mm - What's confusing me, is the format. Is that 00.8 the same as 0.8mm? If it is, then I guess it is fairly close to 1.02mm.

No Cumulus downloads the figure from the console, it doesn't calculate it. Cumulus was showing a negative figure for a while after midnight until Steve put a fix in for that, can't remember what the problem was.

I have a second console, and the ET figures on that do not agree with my primary console (the second console is running older firmware) - so who knows what Davis are doing. Figures noted yesterday...
