A variant Of Keith's suggestion:

[1] "linint2_points" may [will] be a bit slow.

[2] Use "linint2_Wrap" to interpolate NCOM to a 1x1 grid

[3] then use the already generated SCRIP weight files
    to interpolate to the desired grid.
    I have put the above file on ftp
    cd /ftp/pub/shea/POP
    mget map_1x1d*
