Canada Metars

The rmk section of Canadian metars contains entries such as SC6 AC3 C11

Can anyone help with decoding these?

Without the full METAR I have no context, but I believe SC6 is “stratocumulus” with 6/8 sky coverage (therefore broken BKN), AC3 is “altocumulus” with 3/8 sky coverage (therefore scattered SCT), and CI1 is “cirrus” with 1/8 sky coverage (therefore few FEW).



That sounds plausible. Here is the current metar for cyyz:

CYYZ 142000Z 14005KT 6SM HZ FEW100 BKN270 05/01 A2965 RMK AC1CI2 SLP048

Thanks…appreciate it…could not find it any guidance
