wgrib2: -set_lev

Introduction

The -set_lev option changes the level/layer of field. The level/layer description follows that of the -lev option which is used by the -s option. (The -s option is added to the command line whenever command line lacks an inv option.)

Usage

-set_lev LEVEL
  LEVEL is either a level or layer description (12/2015)
