The NRCT is a tool to set up the lateral boundary conditions for a regional NEMO model configuration. The tool is written in Python, largely within the Anaconda environment to aid wider distribution and to facilitate development. In their current form these tools are by no means generic and polished, but it is hoped will form a foundation from which something more formal can be developed. The following sections provide a quick-start guide with worked examples to help the user get up and running with the tool.

The tool essentially uses geographical and depth information from the source data (e.g. a global ocean simulation) and destination simulation (i.e. the proposed regional NEMO model configuration) to determine which source points are required for data extraction. This is done using a kdtree approximate nearest neighbour algorithm. The idea behind this targetted method is that it provides a generic method of interpolation for any flavour of ocean model in order to set up a regional NEMO model configuration. At present (alpha release) the tools do not contain many options, but those that exist are accessed either through a NEMO style namelist or a convient GUI.

PyNEMO has been updated to include integration with CMEMS data repository and the ability to produce tidal boundaries using TPXO or FES2014 as boundary input.
