Yes, clearing metadata for any one data type is easy.  For grid follow these 
steps exactly:

* make sure the LDM is stopped and no more data are being ingested.
* su - awips
* psql metadata

metadata=# delete from grid;
metadata=# delete from grid_info;
metadata=# delete from gridcoverage;
metadata=# \q

The last command exits from psql back to the shell.  Make sure you account of 
the semicolons in the SQL statements.  

After this you will want to rm -rf /awips2/edex/data/hdf5/grid/ and you will 
have a database empty of gridded data, and when you ingest your selected models 
they will be the only records in all three database tables.  The "gridcoverage" 
table is where the geospatial record is stored, with the id linked to in the 
"grid" table.
