Coronavirus Disease (COVID-19)
The growing situation with the Coronavirus (COVID-19) outbreak in the UK is presenting unprecedented challenges for individuals, companies and organisations alike. As a responsible organisation, the IAQM’s primary concern is for the safety of its attendees, members, speakers, exhibitors and staff. We are therefore following the advice of the UK Government to ‘avoid social contact with others and stop non-essential travel to fight Coronavirus’ and as a result, all face-to-face events and workshops for the next few weeks will be postponed.
Where possible we will deliver events and workshops via online platforms. Please refer to the individual event page for further details around each of our events.
We will honour all bookings made for events to date and transfer these to the new event date, details of which will be circulated to you in due course.
We thank you for your support during this time.
IAQM Webinar: Measuring air pollution with low-cost small sensors: Challenges and opportunities
September 22 @ 12:30 pm - 1:15 pm
Small sensors are increasingly being used to measure gases and particles in the atmosphere, as part of academic research and in citizen science projects. Their low cost, portability and low power requirements bring new measurement possibilities, for example to improve the spatial representation in air quality monitoring networks.
However, to deliver quantitative observations requires that sensor performances should be well-understood and characterised.
Furthermore, sensor behaviour depends on the environment of application. Tjarda Roberts, through research, has deployed small sensors at volcanoes where monitoring of gas emissions informs observatories about volcanic activity and eruption hazards. Alongside this she has deployed small gas and particle sensors to measure the high levels of urban pollution experienced in Fairbanks, Alaska, during the cold Arctic winter. These applications enable (and require) the characterisation of small sensor performances in “extreme environments” and can provide valuable insights to the processes underlying the pollution events.
Our speakerTjarda Roberts is a Research scientist at CNRS (French National Centre for Scientific Research). She obtained her PhD in Atmospheric Chemistry from the University of Cambridge in 2009, and undertook postdoctoral research at the Norwegian Polar Institute and a Guest Lectureship at the University Centre in Svalbard, before becoming a CNRS Research Scientist in 2016.
Her research focuses on atmospheric pollution, combining the development of numerical models of the plume processes with deployment of small sensor instruments to characterise the gas and particle emissions. A major research strand is on volcanic emissions and investigation of the plume chemistry that occurs when hot volcanic gases enter the cool oxidising atmosphere.
Another is on applying small sensor technology to characterise gas and particle pollution episodes in the Arctic. She was awarded the CNRS Bronze Medal in 2020.
Our webinars are free for all to attend. With the speakers permission each episode will be recorded and added to our YouTube channel for you to view after the event. Please subscribe to our YouTube channel to view these episodes and make sure you do not miss any new episodes being added.
