Metrology Research Roadmap

In 2021, our leading scientists created twelve roadmaps for our highest priority research areas based on the findings of NPL’s Technology and Measurement Foresighting exercise. The roadmaps show the critical metrology that needs to be in place over the next decade, as well as highlighting the measurement challenges and barriers.
