Introduction

The -get_int2 option prints the values of selected two-byte integers in a grib message. For example if you wanted to see octet N and N+1 is section M as a signed two byte integer, you could use -get_int2 M N 1. The first argument is the section number. The second is the octet number starting from 1 (consistent with WMO grib documentation) and the third is the number of integers to display. The -get_int2 option uses the grib format for signed 2-octet integers.

Usage

-set_int2 SECTION OCTET_NUMBER COUNT

Example

$ wgrib2 f.grb -get_int2 1 6 1  
1:0:1-6=7
