Tropical Nights

[Roebert Akraks]

I would like to have some statistical numbers in my reports. Most of these numbers are available in the monthly / yearly summery, but one thing is missing:

I would like to see the number of "tropical nights", that is the number of days, where the minimum tempeature was above 20°C. I've already done some modifications to the default skin, but I don't know how I could do this.

Thanks for help.

The aggregate min_ge() will do what you want. For example, the number of days of the year with temperature greater than or equal to 20°C would be

$year.outTemp.min_ge((20.0, "degree_C"))

You can make this look a little prettier by playing with the formatting:

$year.outTemp.min_ge((20.0, "degree_C")).format("%3d")

I love functions like that.
 

But when i try to get the number of days with temperatures equal oder below 0°C...

I don't find a solution...
Is that also possible?

try $year.outTemp.max_le((0.0, "degree_C")) instead of $year.outTemp.min_ge((20.0, "degree_C"))

Great!
Works! :)

Thank you.
