makegrid.sh

use makegrid to create a mesh file for cvms4 testing

We have defined two regions that we want to query, and a series of depths. The makegrid.sh script list embedded configuration values. Below are the values used for this exercise

Grid 1:

this is 10m resolution at depths from 80 to 110

34.5 -118.5 33.5 -117.5

HOR_SPACING=0.0001 VERT_SPACING=5 MIN_DEPTH=80 MAX_DEPTH=110 MIN_LON=-118.5 MAX_LON=-117.5 MIN_LAT=33.5 MAX_LAT=34.5

Word count from the output file is:

Grid 2

35.5 -117.5 34.4 -116.5

HOR_SPACING=0.0001 VERT_SPACING=5 MIN_DEPTH=80 MAX_DEPTH=110 MIN_LON=-117.5 MAX_LON=-116.5 MIN_LAT=34.5 MAX_LAT=35.5
