My page on the UCL Geography website is finally up and running! Visit geog.ucl.ac.uk/people/researc… if you are interested in atmospheric chemistry and want to see what I am currently working on 🌥👩🏻‍💻🌩

In 1995 Paul Crutzen, Mario Molina and Sherwood Rowland were awarded the #NobelPrize in Chemistry for helping us understand why the ozone layer was disappearing. #OTD in 1987, nations signed the Montreal Protocol to help us protect it. GIF: NASA/NASA Ozone Watch/Katy Mersmann

At #EGU23? Come along to room F2 at 17.30 CEST where I will be giving a talk on tropospheric vertical profiles of NO2 from TROPOMI and modelling results from GEOS-Chem 👩🏻‍💻🌩️🌍

The 2nd GEOS-Chem Europe meeting (GCE2) will be held at UCL on 14-16 August 2023. Registration is now open! (link -bit.ly/GCE2_registrat…) Please share it with your networks of #atmoschem scientists. DM me for any questions. #GEOSChem #chemicaltransportmodelling #GCE2

DEADLINE ALERT! 2nd GEOS-Chem Europe meeting (GCE2) for #atmoschem modelling scientists in London, 14-16 August 2023. Registration deadline 12 June 2023. Brief registration form here (bit.ly/GCE2_registrat…). DM me for any questions and pls retweet.

Excited for my first in-person European Geosciences Union conference (14-19 April) and even more exciting to attend it with the entire UCL Geography research group. EGU Atmospheric Sci #EGU24 Bex Horner (@bexhorner.bsky.social) Connor Barker

We'll be talking about deriving NOx emissions for cities and hotspots in Asia (Eloise) and Africa (Nana) and vertical profiles of global tropospheric NO2 and ozone from TROPOMI (Bex Bex Horner (@bexhorner.bsky.social) ) ... European Geosciences Union EGU Atmospheric Sci #EGU24 (1/3)

At #EGU24? Come along to my poster at X5.93 between 10.45-12.30 to here me talk about global vertical profiles of tropospheric NO2 and O3 and how we can use these to improve the paramerisation of lightning in chemical transport models! ☁️⚡️👩🏻‍💻

NEW DATA TOOL | Coal mines are a major source of methane. The big culprits could be vastly underreporting their CMM emission. Ember’s new data tool allows you to explore where official data is lacking: ember-energy.org/data/coal-mine…
