A commentary paper I worked on with a bunch of great collaborators was published recently. We discuss how Southern Ocean clouds are influenced by biology and summarise some of the huge efforts to learn more.🔗: and a nice writeup by @Ant_Partnership below
☁️ What makes clouds in the Southern Ocean around Antarctica different from elsewhere in the world?.In this relatively pristine region without dust or pollution, clouds are seeded by tiny airborne particles (aerosols) that come from the ocean itself. 🧵1/6.Images: @NASA WorldView

🚨 Excited to share new work! 💻🌞🌏🌊 We used machine learning with #ERA5 to more accurately simulate sunlight over the Southern Ocean. I learned a lot during this project and can't wait to see what's next.🔗: #ClimateScience #machinelearning @AMS_AIES.

Abstract Earth system models struggle to simulate clouds and their radiative effects over the Southern Ocean, partly due to a lack of measurements and targeted cloud microphysics knowledge. We have...
😎 Our AAPP researchers from partners @AusAntarctic, @BOM_au & @IMASUTAS use #MachineLearning to simulate solar radiation in the Southern Ocean - crucial to improve weather and #climate modelling. 👏 just published in #AIforEarthSystems @AMS_AIES @ametsoc.

. and if anyone is interested in dabbling in some machine learning and how it can be used to isolate the effects of weather on air quality, check out the R package, rmweather, that sparked my interest:

I turned a personal project into a paper that I'm quite proud of. I showed that changing weather is (mostly) not responsible for worsening air quality in an Australian mining town:

It's always a pleasure heading out to Cape Grim. I was the first visitor to the station since March and helped calibrate a new @CSIRO aerosol mass spectrometer there for long-term measurements.
