Pangeo 101 for everyone - introduction to Xarray
Version 1

Workflow Type: Galaxy
Work-in-progress

Abstract CWL Automatically generated from the Galaxy workflow file: GTN 'Pangeo 101 for everyone - Introduction to Xarray'.

In this tutorial, we analyze particle matter < 2.5 μm/m3 data from Copernicus Atmosphere Monitoring Service to understand Xarray Galaxy Tools:

  • Understand how an Xarray dataset is organized;
  • Get metadata from Xarray dataset such as variable names, units, coordinates (latitude, longitude, level), etc;
  • Plot an Xarray dataset on a geographical map and learn to customize it;
  • Select/Subset an Xarray dataset from coordinates values such as time selection or a subset over a geographical area;
  • Mask an Xarray dataset with a Where statement, for instance to only see PM2.5 > 30 μm/m and highlight on a map regions with "high" values;
  • Convert an Xarray dataset to Tabular data (pandas dataframe);
  • Plot tabular data to visualize the forecast PM2.5 over a single point (here Naples) using a scatterplot and/or climate stripes.
