Thanks Jen! Hamilton has been trying to prepare me for living life in a windy place... 😅 but Lethbridge is something else!

Big life update: I'm starting as an Assistant Professor of Chemistry at the University of Lethbridge! 🔬📚🧪

Feeling excited to be stepping into this new role and connecting with the commuity at ULeth. Huge thanks to everyone who's helped me get here—couldn’t have done it without you.

A tricky thing about modern society is that no one has any idea when they don’t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

The report from the BBURNED-@ileaps.bsky.social Fire UNcertainty in CHemistry Emissions, and Modelling (FUNCHEM) workshop last September can be found in the latest @igacproject.bsky.social newsletter (pp 10-13) igacproject.org/sites/defaul...

Our inter-journal special issue on Biomass burning uncertainties: emissions, chemistry, and physics is now open for paper submissions at agupubs.onlinelibrary.wiley.com/hub/journal/...! Please consider this special-issue when submitting any biomass burning research to @agu.org journals (see thread).

An interesting result includes observations of a single wildfire smoke day contributed over 20% of total grime PAH loadings in Calgary (!!) during this study’s 3-month sampling period, showing how wildfire inputs can dominate the grime composition during wildfire season 🔥🌲🏠

Wildfire Smoke Contributions to Polycyclic Aromatic Hydrocarbon Loadings in Western Canadian Urban Surface Grime Wildfires emit large amounts of polycyclic aromatic hydrocarbons (PAHs) into the atmosphere. As PAHs emitted from anthropogenic sources are known to accumulate in urban surface grime present on buildi...

Exciting first, first-author pub from @colourless-cloud.bsky.social exploring the long-term impacts of wildfire events on PAH profiles in surface grime, published in the ES&T special issue "Wildland Fires: Emissions, Chemistry, Contamination, Climate, and Human Health.”

A very exciting first paper from the Joudan lab! 😊

Any #AtmosChem / #IndoorChem folks following me have tips for dealing with any smoke that manages to seep inside? Mainly thinking of how to clean up once the worst is over.

My best guess is wiping down surfaces and washing linens.

Am I forgetting anything?

Thank you 😀

The Measured Impact of Wildfires on Ozone in Western Canada From 2001 to 2019 <em>Journal of Geophysical Research: Atmospheres</em> is an AGU journal publishing original research articles that advance and improve the understanding of atmospheric properties and processes.

Potential bias in the ozone measurements limits our results; however even if we overcorrect the bias, the increase in ozone during wildfires persists!

Schematic overlaid over a panorama of smoky mountains and the ocean. The schematic shows the emission of fire plumes and production of ozone, mixing with urban emissions.

An fun first blusky post and a Valentine's day surprise - SO excited to finally be able to share this work.

We used ozone measurements in Western Canada over two decades to investigate the effects of wildfires on measured ozone. We show the average increase during wildfires is 2 ppbv.
