All,
Looking at the METAR for Leeming, I saw the following:
EGXE 291150Z 17003KT 6000 HZ BKN013 19/16 Q1020 GRN BECMG 8000 BKN018 WHT
OK, got most of that - I can get off the ground easily enough but may not see the Hambleton Hills immediately - but "GRN" & "WHT". I couldn't find reference to those, can anyone elucidate please?
Thanks
