Introduction

The -stats option writes a statistical summary of the field into the inventory. The -max option writes the maximum value and the -min option writes the minimum. These option are useful for quickly determining if the field has reasonable numbers.

Usage

-stats
-max
-min

Example

$ wgrib2 test.grb2 -stats
1:0:ndata=65160:undef=0:mean=83.8696:min=-428.1:max=317.8

ndata = number of grid points
undef = number of grid points with an undefined value
mean = grid point average (not area weighted)
min = minimum value
max = maximum value

$ wgrib2 test.grb2 -max
1:0:max=317.8

$ wgrib2 test.grb2 -min
1:0:min=-428.1
