Quast et al. explain how the FIDUCEO project has reconstructed the in-flight MVIRI VIS spectral response functions from observations of pseudo-invariant calibration sites. Here I give two practically relevant and comprehensive examples how these spectrally degrading spectral response functions may be used in your retrieval of essential climate variables.
What is the difference between "harmonised" and "homogenised" data, and when and where should we be using the harmonised kind?
This blog will pick up a very old question: “Is the Earth flat or a sphere?” and discuss this question with respect to software implementations and matchup data processing.
Relying on Earth targets for the calibration of radiometers used for the generation of multi-decadal FCDR raises the following question: to what extent climate change or other environmental changes can affect the spectral signature of these “pseudo invariant” targets and therefore the consistency of the calibration?
