Comment (by george.gayno@…):
The changes at r96132 were run on Theia for a (216 x 198) CONUS nest and a
halo of '3'. A brief explanation of the boundary file structure:

There are separate records for each side of the domain, which I called
'south, 'north', 'east' and 'west'. The directions have no meaning. I
could have called them 'up', 'down', 'left', and 'right'.
The i/j indices of each record are included. For the fields located at
the grid center (like surface pressure), the i/j dimensions for the
'south' side are:

i_south = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,
