This might be slower than you want, but guaranteed to work. I attached a script to output those points which you can redirect to a file. Here is the STNPLT line I tested after running the script and outputting to a file latlonpt.stn: STNPLT = 0|3/15/3/1|latlonpt.stn Another simple solution is to create a 1 degree CED file (eg proj #003) or just grab the latest GFS and use gdplot2 to plot a marker (eg TYPE=m), set IJSKIP=0, MARKER = 3/15/3/1. I like this since it allows you to use IJSKIP to filter the points to change the spacing (multiples/filter) should you like. Anyhow, thats 2 solutions off the top of my head.
