wgrib2: -spread

Introduction

The -spread option writes the grid values to a specified file as a comma separated values (text) which can be imported into a spread sheet.

   lon,lat,(VARIABLE DESCRIPTION)
   lon-1,lat-1,val-1
   lon-2,lat-2,val-2
   ...
   lon-N,lat-N,val-N
The latitudes and longitudes are only available for supported grids and only the default WE:SN order is supported. The undefined value is 9.999e20.

Use the -undefine option to limit the output to specified regions.

Usage

-spread output_file_name

Example

$ wgrib2 test.grb2 -s | grep ":RH:2 m" | wgrib2 -i test.grb2 -spread data.txt
285:36796469:d=2005090200:RH:2 m above ground:60 hour fcst
The above line extracts the 2 meter RH from file test.grb2 and writes it in data.txt.
