In particular, I like the detailed info on clouds:
<time datatype="forecast" from="2022-09-13T00:00:00Z" to="2022-09-13T00:00:00Z">
<location altitude="986" latitude="45" longitude="90">
<temperature id="TTT" unit="celsius" value="8.9"></temperature>
<windDirection id="dd" deg="353.8" name="N"></windDirection>
<windSpeed id="ff" mps="10.6" beaufort="5" name="Frisk bris"></windSpeed>
<humidity unit="percent" value="55.5"></humidity>
<pressure id="pr" unit="hPa" value="1020.1"></pressure>
<cloudiness id="NN" percent="78.9"></cloudiness>
<fog id="FOG" percent="0.0"></fog>
<lowClouds id="LOW" percent="0.0"></lowClouds>
<mediumClouds id="MEDIUM" percent="46.9"></mediumClouds>
<highClouds id="HIGH" percent="64.1"></highClouds>
<dewpointTemperature id="TD" unit="celsius" value="0.5"></dewpointTemperature>
</location>
</time>
The difference e between low, medium, and high clouds is useful for deciding "where may there be a good sunset?" Most other services just offer the general "cloudiness".
