Metrology for Aerosol Optical Properties (MAPP 19ENV04)
The goal of this project is to enable the Si-traceable measurements of column-integrated aerosol optical properties retrieved from the passive remote sensing of atmosphere using solar and lunar measurements. Atmospheric aerosols have been recognized as a Essential Climate Variables (ECVs) by Global Climate Observing System (GCOS). Their absorption or scattering of solar radiation dominates the uncertainty in the estimation and interpretation of Earth’s changing energy budget.
Currently, climate observation community is largely dependent on reference artefacts and complex calibration procedures, relying on instruments stability and redundancy, and perfect weather conditions. There is no objective metrological framework allowing a reliable calibration, operation and data processing of remote sensing devices.
This projects aims to standardize the retrieval of aerosols optical properties by shortening the calibration chain, reducing calibration downtime of network radiometers and establish a comprehensive uncertainty budget estimations. The radiometers of three main aerosol monitoring networks (AERONET, SKYNET and GAW-PFR) would be characterized at NMI laboratories. Portable in-field calibration devices and cross-network wide implementation of calibration and post-processing procedures would be developed.
Our role
VSL would provide full radiometric characterization of selected filter radiometers from largest aerosol monitoring networks and selected spectral array radiometers from involved stakeholder community. The Si-traceable calibration procedures would be developed and corresponding uncertainty budgets estimated.
Start date: June 1, 2020
End date: May 31, 2023

Virtual experiments and digital twins (ViDiT)
Virtual experiments and digital twins are key enabling technologies to achieve and realise European strategic policies devoted to sustainability and digitalisation within the complex framework of Industry 4.0 and the European Green Deal.
Pushing boundaries of nano-dimensional metrology by light (20FUN02 POLight)
This project addresses this issue by developing novel methods to help bridge the metrology gap and in turn foster KET innovation. More specifically, this project will push the boundaries of optical measurement methods by realising a new generation of optical metrology systems, with unprecedented performances in terms of spatial resolution, traceability, reliability and robustness.
Traceable metrology of soft X-ray to IR optical constants and nanofilms for advanced manufacturing (20IND04 ATMOC)
The optics and semiconductor industries use innovative materials and complex nanostructures in their products whose optical properties are difficult to measure and often not accurately known. This project is developping advanced mathematical methods to traceably characterise these materials for wavelength ranges from soft X-ray to IR.
Traceable industrial 3D roughness and dimensional using optical 3D microscopy and optical distance sensors (20IND07 TracOptic)
To remain competitive, European manufacturers strive to make constant improvements in their manufacturing processes. The surface topography of a component part can have a profound effect on the function of the part. This is true across a wide range of industries (such as precision engineering, automotive and medical).
Metrology for the determination of emissions of dangerous substances from building materials into indoor air (20NRM04 MetrIAQ)
Given that European citizens spend more than 80 % of their time indoors, it is vital to have a healthy indoor environment. Building materials, such as paints, flooring, and from other products used indoors, such as furniture, emit harmful substances.
