Who’s up for a PICO? By Claire Ryder, Associate Professor in the Department of Meteorology Have you heard of the PICO session? The European Geophysical Union (EGU) General Assembly has been offering sessions of a less …

PICO sessions at @egu.eu - a snapshot of what dust scientists think. Are they better or worse than orals and posters? Are they more popular with junior scientists?

Garnet Fire (California) pyrocumulus at 10:11 this morning, from @alertcalifornia.bsky.social Buck Rock 1 towercam. It's a very "dirty" gray-tinged pyrocumulus really injecting a lot of smoke aerosols higher up into the troposphere than many fires do.

Wildfires are preventable. So why does the Iberian Peninsula keep burning? Governments can’t use climate change as an excuse for failing to take preventive measures, scientists say.

The dramatic images from wildfires tearing through Spain and Portugal year after year have become a mainstay of Europe’s increasingly blistering summers.

But experts say that most of the damage is, in fact, preventable — if only authorities at regional, national and European levels would act.

Scientists call for action to address air pollution from space launches Satellite mega-constellation missions behind threefold increase in emissions of climate-altering soot and CO2

“More pollutants are being released ... from rockets and satellites than ever before.

We’re in uncharted territory, as humans have never added this much pollution to the upper layers of the atmosphere."

The CVAO site is unique and so valuable for atmospheric composition research. My thoughts and best wishes go to the staff and everyone at CV.

Tips for producing a short, quick, straightforward paper?

Does such a thing exist?

My papers seem to get more complex and long with every one I write. Need to turn the tables!

#Wildfire smoke from #Portugal and #Spain drifts toward North #Africa, while #SaharanDust surges back across Iberia and #France. This two-way #atmospheric exchange locks both regions in a feedback loop of haze, worsening #AirQuality, altering radiation balance, and amplifying summer #climate stress.

After a ground-based fire passes through an area, especially in a dry climate, dust can be suspended easily from burned areas. Fugitive dust seen here in the @alertcalifornia.bsky.social LaPanza webcam this afternoon.

Thanks to @ecmwf.int Reading for hosting our @unirdg-met.bsky.social Uni Reading Meteorology Department Masters students earlier this week. Students had an inspiring morning learning about ECMWF forecasts, research and data centre. What a great opportunity!

Additional plumes of smoke from wildfires in western Canada are degrading PM2.5 air quality today 11 Jun in the CONUS. The worst conditions are occurring in MT & ND, with lesser but still noticeable impacts across the Great Lakes & Ohio Valley regions. @noaa.gov

The mystery rise of lung cancer in non-smokers The number of lung cancer cases in people who have never smoked is increasing. The disease is different from lung cancer caused by smoking, so what causes it?

How to Stay Safe in the Southern Dust Cloud (Gift Article) A plume of dust is affecting air quality in Florida and may reach other Southern states soon. Here’s what we know about the potential health effects.

Continuing long-range smoke transport from devastating Canadian #wildfires across the Atlantic with another huge plume reaching Europe in the next few days. #CopernicusAtmosphere AOD forecast (from 07/06 00 UTC) atmosphere.copernicus.eu/charts/packa... @copernicusecmwf.bsky.social @ecmwf.int

A spiral-shaped smoke arc from Canadian #wildfires stretches over Hudson Bay into the Arctic. This swirling plume carries aerosols that alter clouds, light absorption, and circulation. A visual trace of how distant fires now mold the far North’s atmospheric system.

It is not uncommon for bursts of strong southerly winds to blow and carry dust from Africa's vast Sahara Desert across the Mediterranean Sea.

Farewell #EGU and Vienna - fantastic to get a good view on departure!

If you haven't come across PICO before - we do 2 minute quick talks from all participants ("2 minute madness") lasting about 30 mins, followed by more in-depth free-flow discussions at interactive poster screens for the rest of the session.

Join us at #EGU25 tomorrow for the Aeolian #Dust session! PICO Spot 1 8:30-12:30 - plenty of exciting talks!

Attendees please have pity on your fellow attendees and officially withdraw if nobody is presenting #EGU25

#EGU25 there is nothing more annoying than withdrawn oral presentations which are NOT MARKED on the schedule as such. Very frustrating when making choices of what to attend. @egu.eu

Always so much more visible from above too - this was out of Heathrow on Monday.

Here in the UK, following a warm, dry and sunny March, we have had the sunniest April on record and 3rd warmest April. Here is a #dataviz with the summary of the weather/climate for the last year.

✅ #EGU presentation done. Note to self: never try to summarise 4 papers in 8 minutes again!

#SaharanDust on the way to Europe, driven by the low pressure system to develop over the Iberian peninsula. Looks like it won't quite hit the UK.

Great to see @edhawkins.org Climate Stripes from @unirdg-met.bsky.social at #EGU25 sparking lots of interest #ShowYourStripes
