WMO 4680 code 02

[libertykite]

Hi,

I have a strange mapping for the wmo code 002: wi-wmo4680-2. wi-wmo4680-02: thermometer

It seems to me that the result should rather be a cloud?

Hi @libertykite,
can you cite what WMO 4680 says about code 02?

Thanks

Hello,

(also trying to use this font with Open Meteo)

Quoted from:

Present weather (from manned (code 4677) and automatic (4680) stations):
https://artefacts.ceda.ac.uk/badc_datadocs/surface/code.html
(and other sources available)
The meaning of 02 seems to be:
02 - State of sky on the whole unchanged

We have to note that this is between those two :

01 - Cloud generally dissolving or becoming less developed
03 - Clouds generally forming or developing

To me, 02 means something like "same cloud level than previous hour".
This is a bit difficult to illustrate as an icon, but has some kind of shortcut, "partly-cloudy", or even "cloudy", seems to be a better representation than "thermometer".

Can we know why "thermometer" has been chosen ?
