Salish Sea NEMO Model Nowcast

Documentation Status

The SalishSeaNowcast package is a collection of Python modules associated with running the Salish Sea NEMO model in a daily nowcast/forecast mode. The runs use as-recent-as-available (typically previous day) forcing data for the western boundary sea surface height and the Fraser River flow, and atmospheric forcing from the four-times-daily produced forecast results from the Environment Canada High Resolution Deterministic Prediction System (HRDPS) operational GEM 2.5km resolution model.

The runs are automated using an asynchronous, message-based architecture that:

  • obtains the forcing datasets from web services
  • pre-processes the forcing datasets into the formats expected by NEMO
  • uploads the forcing dataset files to the HPC or cloud-computing facility where the run will be executed
  • executes the run
  • downloads the results
  • prepares a collection of plots from the run results for monitoring purposes
  • publishes the plots and the processing log to the web

Documentation for the package is in the docs/ directory and is rendered at
