The Eradiate radiative transfer model, designed during the MetEOC-3 project, was subsequently funded for development by the European Space Agency, and a first public release issued in the Spring of 2022. This calibration/validation-oriented model, aiming at high accuracy, is a European contribution towards bringing metrology to space applications. MetEOC-3 supported the design of a new… Read More

Marking a halfway reporting milestone, on 14 September 2022 EURAMET published its MetEOC-4 Publishable Summary that highlights significant recent progress made toward the long-term objective of the MetEOC series: development of an SI-traceable climate observation system. As with preceding projects in this series, MetEOC-4 encompasses a diverse range of research activities, structured according to four… Read More

A travelling reference spectrometer (TRSP) implemented in the traceability concept developed for the Network for Detection of Mesospheric Change (NDMC) within the EMRP project ENV53 MetEOC2 (D2.2.1 to D2.2.13) has reached one year of simultaneously successful operation. It continues operation alongside another Ground-based infrared P-branch spectrometer (GRIPS) at the Oberpfaffenhofen NDMC, for determining Mesosphere’s temperature… Read More

The European reference radiative transfer model was renamed as Eradiate. Information and news about the model are available at In this post, we summarise the requirements elicitation process and give a brief overview of ongoing activities. A part of the activities taking place in the framework of MetEOC-3 consists in laying foundations for the development… Read More

SPECCHIO is a spectral information system designed to hold reference spectra and spectral campaign data obtained by spectroradiometers. MetEOC-3 is going to use a dedicated SPECCHIO spectral information system instance to deal with the multifaceted spectral point data accumulated in various activities related to sensor CAL/VAL. MetEOC-3 is going to use a dedicated SPECCHIO spectral… Read More

The National Physical Laboratory (NPL) published an extensive report Metrology for Climate – Metrology priorities for the earth observation and climate community, containing the recommendations from international research organisations on the role of metrology in supporting climate research. The report summarises the workshop ‘Metrology for Climate’  hosted by the National Physical Laboratory (NPL) on 21-22 May 2015, organised in conjunction with technical… Read More
