METAR remarks
It is almost embarrassing really... but I am not able to decode the following remarks:
KSKF 160355Z 33002KT 7SM SCT035 BKN100 21/21 A2998 RMK WND DATA ESTMD SLP146 8/570 9/240
What does 8/570 and 9/240 mean?
KHDO 160351Z AUTO 00000KT 6SM BR SCT100 18/18 A3000 RMK AO2 SLP146 T01830183 PNO $
What does PNO mean?
Thanks
