Abstract

The Geoscience Community Analysis Toolkit, GeoCAT, was created as part of the National Center for Atmospheric Research’s “Pivot to Python” initiative. The GeoCAT team’s mission revolves around creating an open-development, scalable Python based geoscience computation and visualization toolkit. This mission is realized through our team's implementation of a continuous integration, open-source software development structure to encourage community involvement at every stage of the project lifecycle -- from requirements and specification to testing and deployment.

As a part of NCAR’s Science at a Scale initiative, the GeoCAT team was asked to demonstrate some computational routines using data from the NCAR Community Earth System Model (CESM) Large Ensemble (LENS) hosted on Amazon Web Services (AWS). The computational functions created were designed to be compatible with dask and xarray, and were demonstrated on NCAR’s JupyterHub on Casper.

This seminar will cover an overview of GeoCAT, the development process of computational routines for the Science at a Scale initiative, and what we learned about developing in Python for big data and high performance computing along the way.
