Calibration température

[jojo82]

Hello, I am new, my first name is Johann and I live in the southwest of France.
First of all, Cumulus is really a software very good , it is of the very good work bravo.
I have small one concerns(marigolds) with the calibration of the temperature, it influences well this one but not the windchill and the heat index. Of the blow I have the windwill superior to the temperature.(if no wind)
Here is I hope that I was understood.
Johann.

Yes, you're right.

I am very very close now to removing the calibration facility.

I will try to fix this, but it's going to be difficult.

My heat index calculation uses the calibrated temperature and humidity values, so should be OK. Are you sure it's wrong?

Yes I believe, here is what that gives:
Current data for Caylus (355m)
vendredi 7 novembre 2008 13:30:46

Temperature (°C):
Current 11,1
Trend (per hour) -1,3
Average today 7,4
Wind chill 11,9
Dew Point 8,9
heat index: 12.3
Rel Humidity 90%
the température of the station is 12.3
Wind (km/h):
Current Gust 17,7 SW
Average Speed 7,3 SW

Yes, sorry, I can't read my own code. I should be able to fix this one quite easily. The wind chill is another matter...

Steve, as I said in the other thread - are you serious about removing calibration? There must be several of us in the "keen amateur" bracket who aren't able, for whatever reason, to get a good siting for wind and possibly temperature, and many raingauges are inherently innaccurate. I have calibrated mine against a standard rain gauge and with the calibration factor am now getting excellent correlation. I can't see the point of using a PC and hence Cumulus if the data is badly innaccurate, especially if being widely viewed on the web. I would also add that everything seems to be running great now so I wondered if at some point, if the majority were of the same view, that you might want to consider a moratorium on fixing small bugs and give yourself a "debug and build" holiday!
Cheers, Dave C

No Dave, not serious - it just gets a bit frustrating at times

Phew!
