Valerio Ferracci is a Senior Scientist in the Air Quality and Aerosol Metrology Group (AQAM) at NPL. He has over 15 years’ experience in the measurement of trace gases in the atmosphere, from anthropogenic species in urban areas to biogenic emissions in remote environments, using a variety of analytical techniques, ranging from gas chromatography to various types of absorption spectroscopy as well as low-cost sensors.
He joined AQAM in 2023, having completed his MSci in Chemistry and PhD in Atmospheric Chemistry at University College London. This was followed by work in the Gas and Particle Metrology Group at NPL, and postdoctoral research at the University of Cambridge and Cranfield University, where he explored atmospheric oxidation processes and developed autonomous instrumentation for long-term monitoring of key atmospheric organics.
Valerio is a member of the Royal Society of Chemistry (RSC) and a committee member of two RSC interest groups, the Environmental Chemistry Group (ECG) and the Automation and Analytical Management Group (AAMG). He is an editor of the biannual ECG Bulletin and has chaired RSC events focusing on gas sensing, indoor air and citizen science activities. Valerio is also a member of three working groups (WG) of CEN TC264: WG11 on diffusive samplers, WG12 on inorganic pollutants and WG42 on sensors for ambient monitoring.
Areas of interest
Valerio leads the work of AQAM in sensor evaluation and gas pollutant monitoring. This involves using dedicated exposure chambers to validate the performance of sensors, including pumped and diffusive sampling methods for nitrogen oxides, VOCs, and ammonia, and emerging low-cost sensor system. He supports DEFRA’s local air quality management (LAQM) through QA/QC of NO2 diffusive samplers, as well as the recently established UK Urban NO2 Network (UUNN).
