You will find below a gallery of maps made with cartopy.

• Summary: plot two PFT maps on a page
• Authors: Camille Contoux & Jean-Yves Peterschmitt
• Date: September 2019
• Script: ~jypeter/CDAT/Progs/Devel/contoux/plot_PFT_plio_pi.py

• Load the NetCDF model data with cdms2
• Optionally reduce the number of PFTs before plotting
• Use matplotlib+cartopy to create the plot
  • Create two plots with a PlateCarree projection and a common colorbar
  • Use an A4 portrait (figsize=(8.3, 11.7)) figure size and subplots_adjust in order to improve the page layout
  • Use a listed colormap (and the associated norm), and pcolormesh to plot the discrete PFT values
  • Use a trick to make sure that the black plot border is correctly plotted above everything (top_plot.outline_patch.set_zorder(50))

• Summary: Plot two megabiome maps based on 2 versions of the IPSL model (CM5 and CM6), and compare them to a map with observations
• Authors: Raj Rani-Singh & Jean-Yves Peterschmitt
• Date: September 2019
• Script: ~jypeter/CDAT/Progs/Devel/pasb/PMIP4/Press_Conference_1909/mh_CM6_CM5_megabiome.py

• Load the NetCDF model data with cdms2, and the xlsx observations' data with pandas
• Use matplotlib+cartopy to create the plot
  • Create three plots on a 2×2 layout with an Orthographic projection (centered on Europe) and a common colorbar. Explicitly make the 4th plot invisible in order to make space for plotting the colorbar (colorbar_plot.background_patch.set_visible(False) and colorbar_plot.outline_patch.set_visible(False))
  • Use a square (figsize=(8, 8)) figure size in order to improve the page layout
  • Use the same color scale for both the model data (plotted with pcolormesh) and the observation data (plotted with scatter)
  • Use a common listed colormap to plot the discrete megabiome values (with a norm associated with the megabiome values) and the observations (with a different norm associated with the observations)
