[Radiance-general] What to do when no Weather File is available?

[Wienold Jan]

Hi German,

in those cases, we usually use "Meteonorm" to generate a specific weather data set. It  interpolates from the closest weather stations and they have a huge data basis. For Chile I would guess around 20 (just rough estimation looking at the map).
But it is important to know that the hourly irradiation data is generated stochastically from the monthly data (from the weather stations), so Meteonorm does not use hourly measured data as basis.

So in some kind you get a artificial weather data set, based on the interpolation of real measurements.
It includes also temperature and humidity, all you need for thermal simulation, too.

The output can be chosen in different formats, also epw.

cheers,

Jan

Dear Everyone,

This question may be slightly out of the scope of this list; however, I guess people here might be able to answer it.

I have been wondering, during the last few months, what do people do when there is no available Weather File for a certain location.

An example is my country: there are 5 EPW available for Chile and one of them is for Easter Island. For those who do not know, Chile is a very long country, with many climates and latitudes. For what I remember from my undergraduate classes, solar radiation can be obtained from monthly data. Can we do anything for relative humidity and temperature?

Is there any other source of weather files that can be used? How about Stocastic Weather Files generators?
