“Atmospheric mercury chemistry has evolved over time due to changes in atmospheric composition, especially for changing concentrations of bromine radicals, hydroxyl radicals, and ozone.”

📢 New study agupubs.onlinelibrary.wiley.com/doi/10.1029/...
We investigated the role of pollution changes on the transport of atmospheric mercury. Increases in ozone alter where Hg oxidation happens, leading to shifts in deposition. Check out the study and thanks to funding from HE #MSCA PF!

Schematic of model coupling in the MCHgMAP project
The Multi-Compartment Hg Modeling and Analysis Project (MCHgMAP) design paper is now published in GMD. We are currently working on this model intercomparison to inform global mercury policy efforts.

(at 114 pages, the longest paper I've ever been a part of 😅)
slide for presentation on oxidation of mercury by bromine
If you're at #EGU25 come check out my PICO presentation tomorrow (Wednesday) at the AS3.35: Halogens in the Troposphere session, from 16:15–18:00 at PICO spot 5.4! Will be talking about the role of bromine in the atmospheric mercury cycle.
That was one of the core skills I acquired during my postdoc 😂
Happy to share a personal achievement for me, having my first radio interview about science in Spanish 🫣! Talking about our study of mercury transport through the stratosphere (20 mins in).

oof from fires to floods, rough 💪💪💪
A line graph showing atmospheric CO2 levels at Mauna Loa Observatory from 1955 to 2025. The y-axis represents CO2 mole fraction in parts per million (ppm), ranging from 320 to 420 ppm, while the x-axis is years.
The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.
@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!
Congrats Jenny 🥳!!
Check out this interview about our recent paper investigating mercury transport through the stratosphere. We also covered other aspects of environmental mercury pollution and what mitigation options are out there.

Yes! I think it's driven by the soil emissions parametrization that's sensitive to sunlight, but there also could be some higher uptake of Hg0 by vegetation during daytime when the stomata are open. Either way, it's a nice flickering light 😀
Had some hourly simulation output, so had to play with making some animations! Here's half a year of our WACCM model showing mercury concentrations at the surface. Hard to stop watching those air currents, even if they're blocky at 200 km x 250 km resolution...
Session description for Hg biogeochemical cycling session
Just a reminder that abstract submissions for #EGU25 will close on Wednesday!!
We will be organizing a cross-cutting session on mercury (Hg) biogeochemical cycling 🎄🐟🌬️🌡️. Submit here: meetingorganizer.copernicus.org/EGU25/sessio...
I’m in the Pacific Palisades today for work. The scale of the destruction here is pretty mind boggling.
New study out on the role of the stratosphere in the global mercury cycle. A substantial amount of mercury is oxidized in the lower stratosphere, the layer of the atmosphere above ~10 km, with distinct processes from the troposphere.

Interesting to think about how much anthropogenic tungsten releases there have been though!!
is it time yet to start making a biogeochemical model of the tungsten cycle? 👀💡

EGU session description
For any other Europeans having FOMO to miss out on #AGU24, just a reminder that submissions of #EGU25 abstracts are open til Jan 15 📢.
We will be organizing a cross-cutting session on mercury (Hg) biogeochemical cycling 🎄🐟🌬️🌡️. Submit here: meetingorganizer.copernicus.org/EGU25/sessio...
Our latest paper gives the first estimation of the effect of methanethiol on the global radiative budget. Ocean sulphur is not all about DMS!
Check out this super exciting paper, which changes our understanding on the effect of oceanic sulphur.

The biggest CSIC institute (INIA-CSIC) has been two weeks without internet access because of a cyberattack.. and I thought my laggy zoom meeting was bad 🙃 elpais.com/ciencia/2024...
Somehow I missed the memo... why did no one invite me to these conspiratorial plotting meetings?!?!
Thanks to all coauthors, especially my MIT postdoc advisor
Noelle Selin! Interested to see where this goes in the future, as global experts are currently working on the first effectiveness evaluation of the Minamata Convention on Mercury.
