ncks_file_concatenator.sh

#!/bin/bash
# Script to append individual netcdf files together into a single file using ncks
# Usage: ./ncks_file_concatenator.sh
# Usage: ./ncks_file_concatenator.sh -k  ## keeps input files
# Output: A single WRF-Hydro input file called 'Fulldom_hires_netcdf_file.nc' that contains all the individual high-res
# netcdf file layers.
#
# Notes: This script is frequently used to concatenate the individual netcdf file layers that are generated for use as
# the 'routing grids' in WRF-Hydro.  You will first need to 'unzip' the zipfile that is created from either the stand-alone
# routing grid tool or the one downloaded from the ArcGIS WRF-Hydro pre-processing web service first to create the individual
# file layers that will be concatenated. This script also erases those individual layers when finishing so be sure to keep
# your original zip file.
# Optionally, files are not erased with the -k flag
