European METAR temp/dewpoint plots

[PhilLayton]

Tim,

There are a couple of occasions when European Metars will not plot the temp/Dew points.

The first, and more common is when there is Fog and a vertical visibility is shown

e.g

LFRT 250600Z 26007KT 0150 FG VV/// 13/13 Q1025

The second is that some of the French AUTO stations put ‘//’ infront of the temp/dewpoints.

e.g
LFRO 151300Z AUTO 03009KT 9999 // NSC 17/10 Q1029


In both situations, DAWS thinks that the ‘/’ is a temp/dewpoint parameter and doesn’t recognise the expected data and plots M for both temp and dewpoint. I then have to go into each individual station data and manually type in the temp/dew pt.

Would there be any automatic way around this ?

Thanks

I have added code which will delete groups of 2 or more solidii (not occurring past the RMK marker) for purposes of decoding. When they're used in pressure (Q/////) or wind (/////KT) they'll be replaced with other characters temporarily for decoding purposes so that the missing data can be handled as such.

Thanks Tim,

I forgot to mention the case of RVRs as in:

EDDW 280420Z 25002KT 0800SW 9999N R27/0600VP1500U BCFG FEW015 08/08 Q1022 BECMG NSW

Also prevents Temp/Dew point plotting - I assume your fix will not cover this..
