NAME
Weathericon - collection of weather icons.
DESCRIPTION
This is a redesigned set of icons, meant to be used in conjunction with Locationforecast/2.0. They are available in PNG, SVG and PDF formats.
The icons are not meant to be called on demand like earlier versions, but to be downloaded as a gzipped TAR archive and packed with your application. This will result in better performance and minimize API traffic.
The original icons as used on yr.no can be found on https://github.com/YR/weather-symbols/.
Note: There is a typing error in lightssleetshowersandthunder and lightssnowshowersandthunder (extra "s" after "light").
Unfortunately,
correcting this would mean breaking existing applications,
so it has been postponed to the next version of weathericon/locationforecast.
Variants
Some symbols come in three different variants, for day, night and polar twilight respectively. Others (the ones without sun or moon) are constant during the day. Locationforecast/2.0 will specify the correct variant to use for each hour.
Algorithm
You can potentially try to reconstruct the weather icons in the API from the locationforecast data. A description of the symbolalgorithms is too long to document and support officially, but you can have a look at the source code here if you are interested: https://github.com/metno/weather_symbol.
