Make definition of new grids configurable. #891

Open dwfncar opened 7 years ago

dwfncar commented 7 years ago

The NCEP grids are hard-coded in the vx_grid library. Adding a new grid to that list requires code changes and then recompiling.


As of met-6.0, NCEP Grid 193 was not included in that list but was needed for the DTC's GMTB work.


This task it to figure out a better way to handle grids which are not already defined in MET.


One option is to move all grid definitions from the code to a data file. That data file would need to be installed into share/met and then read at some point at runtime.


Alternatively, we could keep the NCEP grids defined in the code, but allow for user-specified grids. Like GRIB, we could support for an environment variable like MET_GRIDS which points to a single file defining user-specified grids that would be read at runtime.

@TaraJensen Do we need to pull together a small group to discuss this? This is an action item from the Sep. 27 Governance meeting.
