Incredibly high intensity of the devastating #wildfires in Chile🇨🇱 producing thick smoke plumes which are heading out over the Pacific Ocean as shown in the #CopernicusAtmosphere Monitoring Service #ECMWF 5-day forecast of total aerosol optical depth initialized on 5 February at 00 UTC. Noting also smoke from increasing number of early season fires in Colombia🇨🇴 further north.

The #CopernicusAtmosphere Monitoring Service winter #AirQuality guide is available at https://atmosphere.copernicus.eu/cool-dry-conditions-favour-high-pollution-levels-your-cams-guide-winters-air-quality-issues, showing the operational forecast products available to understand the air we breathe.

The animation below shows differences between total column and surface concentrations of nitrogen dioxide on 18 December - an advantage of CAMS is the ability to provide surface air quality information from the assimilation of satellite observed total columns.

Review of the 2022 #Antarctic #Ozone hole in the context of the combine #CopernicusAtmosphere + #CopernicusClimate #ECMWF reanalysis dataset back to 1979 published today at https://atmosphere.copernicus.eu/three-peculiar-antarctic-ozone-hole-seasons-row-what-we-know

For the third year in a row the ozone hole is persisting well into December.

Some #SaharanDust transport for December across N Africa, central Mediterranean and SE Europe over the coming days in the #CopernicusAtmosphere Monitoring Service #aerosol optical depth forecast initiliazed on 7 Dec at 00 UTC. The current hazy conditions over southern Italy will be followed by a larger plume of higher AOD over the weekend.

Hello #chemiverse #chemtoots #ChemMastodon

I am Florent asociate professor at the University of Lille 🇨🇵
I am interested in studying all environmental processes #atmoschem @atmochem using molecular simulations #compchem
#pesticides #PAHs #selenium #halogens #mercury
#gasphasechemistry #aqueousphasechemistry

I started my career in the lab determining rate constants using flow tubes. Now time to estimate them using appropriate methods and kinetic theories.😉

A neat bit for trivia for #atmoschem folks!
Some of us use data from SCIAMACHY (the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY), which is on-board the Envisat satellite.
SCIAMACHY is actually a real word…
Sciamachy, noun, definition: having an argument or a fight with an imaginary opponent

Hi everyone! For atmospheric folks, we have some resources to help you connect.

We have 2 opt-in lists: A google form(https://bit.ly/3Xa0sO3) and a GitHub list (https://jorgesat.github.io/Mastodon-Atmospheric/)

We also have a group created by @H_Herrmann24: @atmochem

If you tag @atmochem, it will autoboost your post. If you folllow the group, you will see those automatic boosts. It's a great way to connect!

We have new folks on the lists, so please check for friends!
