Implementing policies designed to fulfil Paris Agreement commitments will likely involve conspicuous demands for clear accountability for how decisions will be made. Such accountability will, in turn, demand a high bar for trustworthiness of data used as the basis of decisions. So, how can we be sure trusted climate data will be available in time to make a difference? In his opening address at COP27 in Sharm el-Sheikh on 6 November, UN Climate Change Executive Secretary Simon Stiell asked governments to focus on a transformational shift to implementing the Paris Agreement and putting negotiations into concrete actions. With a call to action for principles of transparency and accountability to apply throughout the process, Mr Stiell added, “COP27 sets out a new …

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 radiative transfer model to enable calibration/validation activities in remote sensing. This activity, described in a January 2019 update, produced input for developing the Eradiate radiative transfer model, which since March 2019 has been funded by the European Commission through the Copernicus programme, under the supervision of the European Space Agency. Accurate radiative transfer simulation, without the headaches The first development phase of Eradiate concluded in April …

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 themes matching a set of predefined objectives. It continues existing, and initiates new, lines of research, developing tools, methods, and infrastructure capable of assigning metrologically (SI) traceable uncertainties to data products derived from Earth Observations, with a focus on climate change. More than half of the 54 atmosphere, land, and ocean Essential Climate Variables (ECVs) rely on measurements from space. These are physical, chemical, biological, or …

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 traceable to the SI. Also, several GRIPS instruments from DLR were improved according to the concept developed in MetEOC2 for the TRSP to minimise thermal drifts and straylight.

The European reference radiative transfer model was renamed as Eradiate. Information and news about the model are available at www.eradiate.eu. 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 of a next-generation radiative transfer model to support calibration/validation activities. Initially simply named ER2TM, as in European reference radiative transfer model, this software package is meant to provide a reliable, extendable and comprehensive framework for radiative transfer simulation.   A new name, a new website In June 2018, the ER2TM was renamed Eradiate. This uncommon word, which has the same meaning at ‘radiate’, brings a more distinctive …

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 information system instance to deal with the multifaceted spectral point data accumulated in various activities related to sensor CAL/VAL. SPECCHIO is a specialised software solution to allow the organised storage of spectral data accompanied with detailed metadata to describe the sampling conditions, experimental setups and target properties. One key feature is the easy sharing of data within a research team and the selection of spectral data …

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 experts from European Space Agency (ESA), EUMETSAT, the European Commission, the UK Met Office and the University of Reading. The two-day workshop investigated the role that metrology should play in supporting the robust measurement of Essential Climate Variables. The concept of Essential Climate Variables (ECVs) provides a systematic and internationally consistent framework of variables/parameters to facilitate the monitoring and understanding of climate change and forecast models. …
