Model Products for Grad Course Assignment

An extraction of model fields is required for an assignment about comparison of model results and field observations in the 2021W2 edition of the EOAS PRODIGY directed studies course. The objective of the assignment is to look at the observations of the high salinity, low temperature and high pCO2 event of late July/early August 2015 that is discussed in [Evans_etal_2019] in comparison to fields from SalishSeaCast.

The parameters of the SalishSeaCast datasets to be provided to the students are:

  • Variables: nitrate, temperature, and salinity
  • Day-averaged and hour-averaged fields for 2015-07-25 through 2015-08-04
  • The hour-averaged fields are every 3rd hours (8 hours per day) to keep the file sizes manageable on laptops.
  • The spatial extent of the fields is limited to y-grid points from 600 northward, and depth points from the surface to level 25, again, to keep the files sizes manageable on laptops.

Execution

The task described above can be accomplished using :py:obj:`Reshapr` on the MOAD compute server salish with the commands:

(reshapr)$ reshapr extract Reshapr/docs/examples/extract_evans_nitrate_day_avg.yaml
(reshapr)$ reshapr extract Reshapr/docs/examples/extract_evans_physics_day_avg.yaml
(reshapr)$ reshapr extract Reshapr/docs/examples/extract_evans_nitrate_hour_avg.yaml
(reshapr)$ reshapr extract Reshapr/docs/examples/extract_evans_physics_hour_avg.yaml

where the 4 extraction processing configuration YAML files contain:

:file:`extract_evans_nitrate_day_avg.yaml`

.. literalinclude:: extract_evans_nitrate_day_avg.yaml
   :language: yaml

:file:`extract_evans_physics_day_avg.yaml`

.. literalinclude:: extract_evans_physics_day_avg.yaml
   :language: yaml

:file:`extract_evans_nitrate_hour_avg.yaml`

.. literalinclude:: extract_evans_nitrate_hour_avg.yaml
   :language: yaml

:file:`extract_evans_physics_hour_avg.yaml`

.. literalinclude:: extract_evans_physics_hour_avg.yaml
   :language: yaml

Please see :ref:`ReshaprExtractYAMLFile` for details of meanings and choices available for the items in those YAML files.
