Re: Heat sum & growing season

Hi Paul,

That's the intresting thing of long series and the full show of the winter temp development.
Interesting to look at the winter development of the previous years.
Lot to see there.

Oh, and no apology, I understand. I am happy to have a stronghold on your continent :lol:

Re: Heat sum & growing season

Isn't that the wrong way around. The GDD should use the threshold, and the Sum not! GDD is: (avg > threshold) ? avg - threshold : 0 GDD never goes negative. Anyway, a snapshot of my data on my test default web site (new Temp Sum button)... https://weather.wilmslowastro.com/test/newMX/historic.htm N...

Re: Heat sum & growing season

Did you know the UK is mild and wet! :lol: How about NL? That is why the seasonal graph actually is more important in the Nordic countries (or Canada, Siberia etc...). The Temp Sum is more relevant in the milder zones (e.g. in NL it is used for tulip bulb calculations in the Keukenhof ). They can't...

Re: Heat sum & growing season

There are two graphs: Temp Sum and GDD this is my code for the GDD: do { TempSum += yearList[ i ].AverageTempThisDay - TempReference; ma.Append( $"[{yearList[ i ].ThisDate.DayOfYear},{ TempSum.ToString( "F1", NumberFormatInfo.InvariantInfo )}],\n" ); } while ( ++i < yearList.Count ); And this is for...

Re: Heat sum & growing season

I'm struggling to understand the usefulness of the heat accumulation? The graphs @pes has linked, show the accumulation going below zero, I would have thought you would have a threshold, and add the accumulation above that threshold. My logic is that once the temperature drops below the point at wh...

Re: Heat sum & growing season

Likewise, the maximum temperature is usually capped at 30 °C because most plants and insects do not grow any faster above that temperature. However, some warm temperate and tropical plants do have significant requirements for days above 30 °C to mature fruit or seeds. usually... : a lot of effort f...

Re: Heat sum & growing season

I don't get why you wish to use the max/min method when the average temp is already present in the dayfile (CMX averaging)

The only thing you need to do is summing it up.

And btw, I already implemented both charts in Cutils (including a parametrised base temp).

Re: Language file sharing

And here is the German languagefile (H/T @hokodata who asked me to put it here) File created 14/4/2021. NOTE: Holger made a true multi language site which is not very easy under Cutils. It may start me to think on creating an infrastructure which makes this easier. That won't be done very soon though.

Re: Heat sum & growing season

I will not reply into detail on the reaction of sfws and I have no intention to follow up on this discussion the way it goes. But I will give a short response. The GGD and Temperature Sum have nothing to do with the physiology of the plant. They are heuristics used by farmers, foresters and in gener...
