# netcdf-scripts

This repository contains convenience scripts for viewing and editing netCDF files.

## Contents

All scripts are in the `scripts/` folder:

1. `isCoards`: Determines whether a netCDF file adheres to the COARDS netCDF conventions.  This is required if the files are to be read by GEOS-Chem Classic or GCHP.

   

2. `nc_chunk.pl`: Deflates and chunks a netCDF file.  See the [Work with netCDF files](https://geos-chem.readthedocs.io/en/stable/geos-chem-shared-docs/supplemental-guides/netcdf-guide.html#chunk-and-deflate-a-netcdf-file-to-improve-i-o) for more information.

   

3. `ncd`: Wrapper script for the `ncdump` command, which lets you view the header information of a netCDF file.

   

4. `time_units`: Wrapper script that allows you to reset the `time:units` attribute of a netCDF file.

   

5. `time_unlimited`: Wrapper script that allows you to set the `time` dimension of a netCDF file to `UNLIMITED`.  NetCDF files must have an `UNLIMITED` time dimension before they can be concatenated with e.g. the NCO `ncrcat` command.
