Brett, I have placed a tar file of dcgrib in the gbuddy ftp account under nawips-5.4/patches/dcgrib_991011.tar.Z This version of dcgrib will create a northern hemeisphere CED grid which can be comprised of 4 tiles. Your tiles C and D will be written to the appropriate row offsets in the grid. I have tested the decoder on the 2 gribs you sent me and compared them against the grid that NAGRIB produces as well. Since the two UWND grids you sent me were for different times (eg C = f000 and D=f012), I did not have a single image to look at, but the data decoded into the individual tiles does correctly overlay with the individual files created by NAGRIB. Please let me know if this accomplishes what needs to be done. To install, download into $NAWIPS and unpack with: zcat dcgrib_991011.tar.Z | tar xvf - Then build with: cd $NAWIPS/unidata/ldmbridge/dcgrib make clean make all make install make clean It is very important to run the "make clean" since I have changes the sizes of data arrays in geminc.inc, so you don't want any old objects around.
