1. summary: A 60-level topography generated for the traditional POPx1 horizontal mesh (horiz_grid_20010402.ieeer8). 2. created by: Bruce Briegleb 3. date and time: Oct 2008 4. platform: 5. dataset format: ieeei4 6. endian: big 7. archival copy location: 8. creation details: 10 October 2008 Description of gx1v5 kmt modifications for overflows. Bruce P. Briegleb Rationale is to modify kmt for the Denmark Strait and Faroe Bank Channels, for sidewall overflow velocities, as well as to alter topographic bottom paths and basin widths for more realist resolved flow response. Below is a list of all the kmt changes, given as ig,jg,kmt_org,kmt_new where ig,jg are the global array kmt indices, kmt_org is the original gx1v5 kmt, and kmt_new is the modified kmt. The two overflows are given separately, and some of the individual changes have ! comments on the right.
