πŸŽ“ CoMet Training – Met4EO Uncertainty Traingin Workshop 2026

πŸ“… Start: Thursday 21st May

πŸ•°οΈ End: Friday 22nd May

πŸ“ Location: National Physical Laboratory (IQST)

On this page you’ll find links to the training materials.

This session covers key concepts around uncertainties, with guided exercises using the CoMet toolkit. You will:

  • Gain a conceptual overview of uncertainties in Earth Observation data processing.
  • Learn how to use the CoMet tools in practical workflows.
  • Apply methods through interactive notebooks hosted on Google Colab.
  • πŸ“ƒ CoMet toolkit introduction: A short introduction to key concepts, why they matter, and how CoMet helps with uncertainty handling.

β€’ Simple measurement functions

β€’ Propagating error correlation information

β€’ Random and systematic uncertainties

Exercise 3: From Spectrometer Measurements to NDVI (Click here to open exercise)

β€’ Spectrometer example from demo and uncertainty tree diagram session

β€’ Propagate uncertainties from raw data, to reflectance and NDVI

β€’ Random and systematic uncertainties

Exercise 4: Multi-Dimension Datasets (Click here to open exercise)

β€’ Use obsarray to store error-correlation information for multi-dimensional measurement datasets - such as from Earth Observation.

β€’ Propagate uncertainties from these datasets through measurement functions using punpy.

(If time allows) Exercise 5: Uncertainty propagation for inidividual products in a timeseries

β€’ Often, products are processed one at a time, and thus uncertainties need to align with this

β€’ This exercise explores handling error correlation in such situations.

(Friday) Exercise 6: Work on your own use case or HYPERNETS (Click here to open exercise)

β€’ Get familiar with sample EO data and their uncertainties (HYPERNETS & S2)

β€’ Perform validation comparisons between these sensors

β€’ Generate and interpret uncertainty-aware outputs
