Introduction

The -AAIGlong option is similar to the -AAIG option except for a new file name convention for the output. The -AAIGlong option writes the data into a Ascii ArcInfo Grid file. This option is experimental and only supports equally spaced lat-lon grids. (You can use the -new_grid option of wgrib2 to create an equally spaced lat-lon grid.) Each field is written to different file in the current directory.

File name convention for ouput: *.asc

The file name convention

   NAME=(wgrib2 -S)
   remove (message number)[.submessage number]:(byte location): 
   remove trailing semicolon if any
   replace "/" by " DIV "
   replace "\" by " BS "
   replace ":" by "_"
   replace "'" by " Q "
   replace '"' by " Q "

   Note: The (wgrib2 -S) output can change between different versions of wgrib2.
   The grib table can be updated.
   The new metadata can be added to the inventory in order to uniquely 
     identify fields.
   In rare cases, the format of the metadata has been updated.

   If you need to format of the NAME to be unchanging, please freeze the
    version of wgrib2.

Usage
