[GEMPAK #ZWT-869984]: SFCFIL errors

Daniel,

In sfcfil, use:
 SFOUTF   = test.gem
 SFPRMF   = bufr.pack
 STNFIL   =  
 SHIPFL   = y
 TIMSTN   = 1/8762
 SFFSRC   = UNKN
 GEMPAK-SFCFIL>

Your sffsrc must be one of the recognized types, not the name of a data file as 
you had previously.

For your data set, the packing file can be:
SELV         0.      10000.      1.
TMPC       -50.         50.     .1
DWPC       -50.         50.     .1
SPED         0.        60.      1.
DRCT         0.        360.     10.
PRES       600.       1080.     .1

Don;t store the SLAT and SLON as a parameter here.

In your input SFEDIT file, you have a few small corrections:
The PARM line had comma instead of a ";". Use:
 PARM = SLAT;SLON;SELV;TMPC;DWPC;SPED;DRCT;PRES


Change your times from 4 digit years to 2 digit years (I did a quick global 
replace of 20060713 with 060713).

In your SLAT and SLON data currently, you have -104.59 as SLON for every 
station, but
have what looks like SLON specified for the SLAT column, so you just need to 
fix that.

I ran SFEDIT as:
 SFEFIL   = 2006071313_rtmagemob.dat
 SFFILE   = test.gem
 GEMPAK-SFEDIT>r

 SFEDIT PARAMETERS: 

 Edit file:           2006071313_rtmagemob.dat                                  
                                                                      
 Output surface file: test.gem
