We’re pleased to invite you to a hands-on tutorial session on the CoMet (Community Metrology) Toolkit, taking place during ESA’s Very High-resolution Radar & Optical Data Assessment (VH-RODA) 2025 Workshop which will be held at ESA-ESRIN, Frascati (Italy), from 17-21 November 2025. The tutorial itself will take place:

🗓 Wednesday 19th November

🕒 12:50 – 13:40

📍 ESA-ESRIN (Frascatti, Italy), Big hall

The CoMet Toolkit (www.comet-toolkit.org) is an open-source suite of Python tools for handling and propagating uncertainties and error-correlation in measurement data. Originally designed for Earth Observation (EO) applications, CoMet’s flexible tools can be applied to any dataset involving uncertainties — making it highly relevant for anyone working with measurement functions and data analysis in Python.

🗸 In this tutorial, we will:

  • Introduce the key concepts behind metrological uncertainty propagation
  • Walk through the core components of the toolkit:
    • punpy – for robust uncertainty propagation with support for error-correlation structures
    • obsarray – for managing and storing uncertainty metadata in a self-describing, traceable format
  • Work through a sensor calibration example using Google Colab-based Jupyter notebooks

This session will be tailored to implement rigorous, traceable uncertainty handling in satellite Cal/Val processing chains.

🗸 No installation is required beforehand – all examples will run in Google Colab!
