EMOSLIB also provides two command-line tools for using interpolation. Assuming a recent version of the EMOS library, there are two tools that can be used.
In the 'bin' directory there is a command 'emos_tool' which can be used as:
| Code Block | ||
|---|---|---|
| ||
emos_tool --regular=256 [--area="40/-10/31/20"] |
...
in.grib out.grib |
The grid specified for the --regular option follows the grid naming convention for EMOSLIB here: Reduced Gaussian Grids.
Another command can be found in the 'tools' directory. This allows the interpolation function to be specified and is more flexible:tools/int example
| Code Block |
|---|
tools/int --INTOUT:gridname=F256 --INTOUT:area="40/-10/31/20" --input=1.grib --output=2.grib --intf2 |
...
Here 'F256' means 'full-grid' not reduced, and --intf2 is the EMOSLIB interpolation function to be used.
