Metar decoding
Hi,
I came across the following metar;
METAR EBLG 090750Z 27011KT 5000 -SHSN SCT003 BKN005 00/M01 Q1022 R23L/729195 TEMPO FM0815 1000 SHSN BKN003=
I'm a bit confused about R23L/729195
If I get it right, I understand that RWY 23L is covered with ice (7) from 11% to 25% (2) and its braking action is good (95)
But what about that '91'? It should stand for the depth of deposit but '91' is not used for this information or do I miss something?
Thanks a lot for your help
