Example recipes#

Overview#

These are example recipes calling example diagnostic scripts.

The recipe examples/recipe_python.yml produces time series plots of global mean temperature and for the temperature in Amsterdam. It also produces a map of global temperature in January 2020.

The recipe examples/recipe_easy_ipcc.yml reproduces part of figure 9.3a from IPCC AR6 - Climate Change 2021: The Physical Science Basis. It demonstrates how ESMValTool can be used to conveniently analyze many models on their native grid and is described in detail in the blog post Analysis-ready climate data with ESMValCore.

The recipe examples/recipe_extract_shape.yml produces a map of the mean temperature in the Elbe catchment over the years 2000 to 2002. Some example shapefiles for use with this recipe are available here, make sure to download all files with the same name but different extensions.

The recipe examples/recipe_decadal.yml showcases how the timerange tag can be used to load datasets belonging to the DCPP activity. Produces timeseries plots comparing the global mean temperature of a DCPP dataset with an observational dataset.

Available recipes and diagnostics#

Recipes are stored in esmvaltool/recipes/:

  • examples/recipe_python.yml

  • examples/recipe_easy_ipcc.yml

  • examples/recipe_extract_shape.yml

  • examples/recipe_decadal.yml

Diagnostics are stored in esmvaltool/diag_scripts/:

  • examples/diagnostic.py: visualize results and store provenance information

  • examples/make_plot.py: Create a timeseries plot with likely ranges

  • examples/decadal_example.py: visualize results and store provenance information

User settings in recipe#

  1. Script examples/diagnostic.py

    Required settings for script

    • quickplot: plot_type: which of the iris.quickplot functions to use. Arguments that are accepted by these functions can also be specified here, e.g. cmap. Preprocessors need to be configured such that the resulting data matches the plot type, e.g. a timeseries or a map.

Variables#

  • tas (atmos, monthly, longitude, latitude, time)

  • tos (ocean, monthly, longitude, latitude, time)
