Introduction

The -Match_inv option is identical to -match_inv except the "d=YYYYMMDDHH" and "D=YYYYMMDDHHmmss" fields are swapped in the inventories. The wgrib2api uses -Match_inv option to create its inventories.

Wgrib2 inventories can be used as index files and as metadata to create grib files. For index files, the -match_inv makes a fine index file as it exposes a number of important parameters that you may want to search upon. The problem with using these files for metadata for creating grib files is that it uses a reference time of "d=YYYYMMDDHH". Some applications require a reference time that includes minutes (mm). The -Match_inv option uses a reference time of "D=YYYYMMDDmmss" which solves this problem.
