Hello everyone,
I am transitioning between GEMPAK 5.7.3 (SGI IRIX) and 5.8.3a (Linux
FC4). I have noticed that on my surface plots, many stations from the
Montreal mesonet transmitted in METAR format in the DDS/IDS feed are
not decoded the same way. In 5.8.3a, I am missing the parameters in
the RMK section, though that in the WMO ascii data the data is the
same (in that particular case only P03C is missing, along with no
tenth precision on temperatures):
368
SACN90 KWBC 081309
METAR CWEW 081300Z AUTO 25007KT 02/M01 RMK AO1 SLP164 T00231012
52017
It is also transmitted in old SAO format, but before (in time) the METAR report:
332
SACN90 CWAO 081300
WEW SA 1300 AUTO8 M M M 164/02/-01/2507/M/ 2017 32MM
The P03C group is 52017 in METAR format in the RMK section. I get in SFLIST:
WEW 051108/1300 1016.40 -9999.00 2.00 -1.00 7.00 250.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00
instead of:
WEW 051108/1300 1016.40 -9999.00 2.30 -1.20 7.00 250.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
2017.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00 -9999.00 1.70 -9999.00 -9999.00 -9999.00
-9999.00 -9999.00 -9999.00 -9999.00 -9999.00 -9999.00
-9999.00
What did change??
