What does the SOG part of this METAR mean?
The RMK section:
AO1 = an observation
taken by equipment without a precipitation type discriminator (rain/snow)
SOG 32 = snow on ground, thickness 32 cm
6023 = beats me, I'll keep looking...
SLP176 = sea level pressure: what the current barometric pressure at measurement location would be at sea level, 176 stands for 1017.6 hPa (10 is omitted as persistent)
T10471068 =temperature and dewpoint in two four digit groups: first 0 or 1 for above or below zero degrees, then three digits for tenths of Celcius grades, so in the case above temperature is -4.7 deg C, dewpoint is -6.8 deg C
