Christian, This can be a little tricky to get exactly what you want, but if you are patient it can be done. I do it here at the U.W. in my plots (see http://www.atmos.washington.edu/images/sfc_pgtsnd/2005121616.gif for an example). There is a priority field in that you can use in sfmap to filter by. For example, SFPARM = skyc:.75;tmpf;wsym:1;smsl;blnk;dwpf;spri<4;brbk:1:1;mark:2 COLORS = 32;2;23;0;4;0;32 FILTER = 0 will plot only stations with a priority of 4 and below. Assigning that a color of 0 will keep that number from being plotted. Personally, I run my own GEMPAK file creator to add my own priorities. If you are running dcmetr using $GEMTBL/stns/sfmetar_sa.tbl as your station file, you'll need to try putting an integer out in the 76th column of that file for your stations. Since everything defaults to 0, you'll probably just want to assign a higher value to YUL and plot it separately. And, your changes to priority won't take effect until you create a new GEMPAKfile.
Note that I also have to specifically tell sfmap to not plot certain stations. For instance, the following plots all stations with elevations between 0 and 2000 meters, but leaves out CMCT AREA = SELV:0:2000/-@CMCT I find AREA statements extremely quirky, however, especially the behavior with the -@STID syntax. Your best bet if you want to subtract multiple stations, is to do something like this: AREA = 40;-130;50;-110/-@ksea/-@krnt/-@ktiw FILTER = 0 Where your FILTER value will may need adjusting.

Hi everyone, I am trying to get some main stations plotted in priority in sfmap. By example, I would like YUL to be in absolute priority, since it is a manned station. I tried to put YUL in the top of stations tables lsfstns.tbl and sfmetar_sa.tbl with no avail. Stations like CMCT comes up first... Any idea how can I force that? Many thanks, -- Christian Pag? UQAM
