CH4-boundary-condition-scripts

Description

Scripts, originally developed by Lu Shen, to generate Tropomi smoothed fields for usage as scaled boundary conditions.

Instructions for running on aws

1. Make sure you have run the GCClassic simulation for the time period you are creating boundary conditions for. The run directory can be found at /home/ubuntu/run_gc_13.3.3
2. Make any changes necessary to the boundary_condition_config.yml file. This will likely include changing the default dates.
3. cd into Step1_convert_GC and run ./template_archive.py. This will create a number of pkl files in the data_converted_BC directory. Note: make_run.sh is used for parallelising the creation of BC files. This is not yet supported on aws until we set up sbatch.
4. cd into Step2_regrid_fast and run ./read_daily.py. This will create a Daily_CH4.ncfile in the Step3_correct_background directory.
5. cd into the Step3_correct_background directory and run Rscript correct_final.R. This will create the Bias corrections file for CH4: Bias_4x5_dk_2_updated.nc.
6. cd into Step4_write_boundary and run ./write_boundary.py. If you have the upload_to_s3 setting set to true in your config file, the created boundary conditions will be uploaded to s3 in the config-specified output bucket.

Note: because tropomi data is hosted in a different aws region you will incur costs for downloading tropomi data.
