Working with several European institutes, we are participating in a European Partnership on Metrology (EPM) black carbon standardisation project which addresses these metrological issues. This project will evaluate photo-acoustic and photo-thermal interferometry methods as reference methods for light absorption coefficients measurements and will provide guidelines on testing and calibrating black carbon monitors.
This work will lead to the very first European documentary standard on BC-related metrics which will allow insight into the adverse effects of black carbon on the climate, human health and the natural environment.
