The European project, coordinated by the SFI-Davos (Switzerland), aims to develop methods for measuring direct, diffuse and global solar spectral irradiance between 290 nm and 400 nm with an uncertainty of 1% to 2% and new instruments for rapid measurement of spectral irradiance (UV to TF spectroradiometers) to take into account rapid variations in atmospheric conditions (measurement duration less than 10 s and repetition time less than 1 min).

Objectives

Improved measurements of UV radiation from the solar spectrum reaching the ground

Estimation of uncertainties of matrix spectroradiometers

Development of a photodiode array spectroradiometer optimized for spectrum measurement between 290 nm and 400 nm and with minimization of stray light

The noise of machinery or equipment is a technical characteristic generally declared in terms of acoustic power (power level in dB in relation to a reference acoustic power of 10-12 watt). In Europe, this declaration of power is often imposed by regulation.

Objectives

Develop a primary reference source to disseminate the acoustic power unit

This European project aims to improve metrological traceability for the measurement of the main essential climate variables (ECVs) defined by the Global Climate Observing System (GCOS). This will address the need for improved accuracy in environmental parameter measurements and assist climatologists in implementing reliable climate change models.

Objectives

Improve metrological traceability for the measurement of key climate variables defined by the Global Climate Observing System

The term "greenhouse gas" (GHG) includes various gases naturally present in the atmosphere (CO2, CH4, N2O, O3) or resulting from human activity (CO2, CH4, CF4, SF6,...) and which have in common to absorb solar radiation re-emitted by the Earth's surface, thus contributing to global warming.

Objectives

Develop reference gas mixtures for high-impact GHGs (CO, CO2, CH4, N2O, SF6 and other fluorinated gases)

Develop dynamic generation methods allowing the preparation of reference gas mixtures directly on site at trace level concentrations (< ppb)

The Sixth Community Environment Action Programme, adopted by Decision No 1600/2002/EC of the European Parliament, established the need to reduce pollution to levels that minimise harmful effects on human health. One of the levers for achieving the air quality objectives set by the EU is to act on emissions linked to transport (air, sea and road).

Objectives

To develop primary measurement methods for the analysis of platinum group elements (PGE) emanating from the release of catalytic exhaust pipe particles

By absorbing nearly a third of CO2, the oceans play a crucial role in controlling the climate of our planet. However, the accumulation of CO2 in the oceans leads to a decrease in the pH of seawater, a phenomenon known as "ocean acidification".

Objectives

Provide the necessary tools to strengthen the metrological concepts used in oceanography and thus improve the quality of ocean monitoring (pH, conductivity, seawater composition)
