**What it does**

First the tool will give general information about the input in a 'info file' output. (command $ncdump -h inputfile)

Then, a general tabular 'variables' summarize dimensions details inside each available variable.


The summary tabular file has the general structure :


    Variable1    Var1_Number_of_Dim    Dim1    Dim1_size   ...    DimN    DimN_size

    VariableX    VarX_Number_of_Dim    DimX1   DimX1_size  ...    DimXN   DimXN_size

    ...


**Input**

A netcdf file (xxx.nc).

**Outputs**

An Information file.

A summary tabular file.


--------------------------------

The Netcdf Info tool use the netcdf functions : https://www.unidata.ucar.edu/software/netcdf/docs/index.html

Run this tool before considering using Netcdf Read.
