The goal of MetEOC is to create metrology tools and frameworks needed to underpin a global climate observing system.

An objective of MetEOC is to develop SI traceable measurement methods with associated uncertainties for bio-geophysical parameters at pixel level and accounting for scene specific characteristics including the means to optimally parameterise, validate and assess the uncertainties of retrieval algorithms. This will consider harmonisation of sampling methods including optical and SAR based techniques.

Capabilities of CEOS Cal/Val test-sites such as RadCalNet will require extending from ‘bright targets’ to biophysical surfaces, demanding challenging new spectral/spatial corrections.

Long-time-base datasets together with operational temporal-continuity need scene/pixel dependent uncertainty characterisation – techniques using machine learning will be explored. Furthermore, transformational algorithms such as radiative transfer codes will be metrologically evaluated in physical and virtual environments.
