#llcrnrlon,llcrnrlat are lon and lat (in degrees) of lower
# left hand corner of projection region.
-where `proj='lcc` selects the [Lambert conformal conic][lcc]
+where `proj='lcc'` selects the [Lambert conformal conic][lcc]
projection for the x/y points, and `ellps='clrk66'` selects the
reference ellipsoid for the lat/lng coordinates. The other
coordinates are LCC parameters that select the [AWIPS 221][awips221]
