Installation

This package will typically be installed as part of the GGG installation process. Installation outside of GGG is not officially supported. If that is needed, the recommended steps are:

1. Create a conda environment with Python 3.7 and the dependencies specified in setup.py
2. Activate that environment
3. In this directory, run python setup.py --no-user-cfg develop

This will install the entry point scripts into the bin directory of your environment. To install them elsewhere, add the --script-dir option to the python setup.py call, e.g. --script-dir ./scripts to install to ./scripts

Included programs

• write_netcdf: write a TCCON private netCDF file from GGG output or a public TCCON netCDF file from a private one
• compare_netcdf: compare two TCCON netCDF files for differences
• concat_netcdf: concatenate two TCCON private netCDF files along their time dimensions. Public files are not supported.
• update_site_info: update site-related attributes in a TCCON netCDF file
• subset_netcdf: subset a private TCCON netCDF file along its time dimensions. Public files are not supported.
• update_manual_flags: set manual quality flags in a private TCCON netCDF file.

All programs include command line help, use the -h or --help flags to see specific options and flags.

Common usage

Write a private TCCON file - this assumes it is being run in a directory with all of the GGG output and that your GGG run used the "pa_ggg_benchmark" runlog:

write_netcdf pa_ggg_benchmark.tav

Create a public TCCON file from the private file, pa20040721_20041222.private.nc:

write_netcdf --public pa20040721_20041222.private.nc
