<div dir="ltr"><div>Aaron,<br></div><div dir="ltr"><div><br></div><div>That is odd. I tried downloading a single 15km ugrd10m file. I ran '<a href="http://g2ctl.pl">g2ctl.pl</a> CMC_reg_UGRD_TGL_10_ps15km_2014032512_P012.grib2 > temp.ctl' and 'gribmap -i temp.ctl'. In grads, I typed 'open temp.ctl' and then 'd ugrd10m' (without setting any x, y, z, or t dimensions), and it plots fine. Below are the contents of the ctl file. You can compare it to yours. </div>
<div><br></div><div>Also, here is the webpage with the 15km grid grib info: <a href="http://weather.gc.ca/grib/grib2_reg_15km_e.html">http://weather.gc.ca/grib/grib2_reg_15km_e.html</a></div><div>It includes information about which fields are on a different grid (I had speculated incorrectly about the ABSV being one of them).</div>
