Guest post: Twenty years of AERONET-OC provision of ocean colour calibration and validation data
Long term operation of network supporting the validation of satellite ocean colour observations contributing to the quantification of these natural ‘sinks’ of carbon. Marking the twentieth anniversary of the Ocean Colour component of the Aerosol Robotic Network (AERONET-OC), Frédéric Mélin, of MetEOC-4 External Funded Partner JRC, summarises ‘fruitful encounters’ between the AERONET-OC ocean colour network and MetEOC projects. But first, some background. An objective of the MetEOC series of projects is to develop satellite derived SI-traceable measurement methods to measure greenhouse gases emissions and carbon sinks. The context for that requirement is that knowledge of the amounts of greenhouse gases absorbed by such sinks will be a critical part of the equation for any workable net zero strategy. Currently, the earth’s oceans …
