isn’t there some fancy algorithm that calculates the hours of sunshine (I guess it would involve solar radiance measurement, location and time of the year). Couldn’t that be added to the list of calculated values?

It could be added but it’s a bit beyond the scope of the application. There are third-party applications that do offer this data

Why is this beyond the scope of the application? Currently it shows quite a few calculated values. Unless you are a real weather geek (oops, aren’t we all :wink:) this derived value is one that appeals to the casual hobbyist (like me)

David has addressed this in posts several times.

I did search for ‘hours of sunshine’ on this forum, but came up with zero results. (I might be searching wrong of course). If this is being discussed elsewhere could you direct me towards that discussion?

Not that specifically but about the scope of the application and the role of third-party developers. I’ve asked for several items to be added to the application and finally decided to start developing my own.

But I wouldn’t put sun and moon calculator in the same league as ‘hours of sunshine’, as the latter is a bit stronger related to wheater itself.

The code I posted gives the hours.

o sorry, I thought it calculated sunrise, sunset, and perhaps the difference. I’m not talking about daylight hours, but the hours during the day that the sun actually shines. Something that is usually measured with a Campbell–Stokes recorder (a big glass ball used as a magnifying glass that burns pa…
