Air Quality Scientist @RicardoGroupPlc - work on #airquality #climate #modelling #satellite. La curiosité est mon leitmotiv. Views my own. @matthieupommier.bsky

1/4 I am glad to share my new study for this new year, estimating annual total nitrogen oxides #emissions and mean NO2 #lifetimes using #TROPOMI #satellite observations in the #UK. https://t.co/aPc9sp9azj

6/6 Two third of the reduced nitrogen deposition (RDN) is composed of NH3 dry deposition. Total N deposition declines by 15–18% in source regions depending on the scenario, but national average reductions remain modest.

1/6 I'm pleased to share our new peer-reviewed study, analyzing the effect of #farming #mitigation measures on #ammonia concentrations and #nitrogen deposition in the #UK: https://t.co/3fKsccqlP4. This paper is a good illustration of using CMAQ to analyze emission scenarios.

5/6 This study focused on annual changes and conclusions might differ if other periods (e.g., daily, monthly, seasonal) are selected for exposure analysis.

Documentaire très intéressant sur les collusions en #Trump, son administration, le parti républicain et #Poutine et la #mafia russe : https://t.co/BGcQxN1DuL

I'm glad to share our new report studying the effect of #mitigation measures on #airpollution and #greenhousegas #emission reductions, and their impact on #airquality in #Europe https://t.co/x8loy9rmwF

[Matthieu Pommier @matpom45]

Always rewarding to have the possibility to attend conferences such as the #IASI conference. I am always fascinated to discover the improvement and the novelties in #space science, such as the improvement in the #methane retrieval, the detection of #ammonia point sources, etc.

I've also created my profile on #BlueskySocial 😉

#Heat-related deaths, now six times more frequent in southern than in northern #Europe, will occur 9.3 times more frequently in the south than in the north by 2100... see this interesting study. https://t.co/OySSIHWefj

I am glad to be involved in this exciting project. New #airquality modeling results will be presented soon for #UAE, in the meantime, check this page for the introduction of this #modeling #system and the challenges we face in its development. https://t.co/hxEihw5xLo

@cassouman40 ah bah si la condition "if Hollande_presence == 1:" est remplie, il est certain de pleuvoir.

A voté ! Bon… ça a été bien galère pour trouver le lien du portail de vote… 20 min pour trouver l’info et au final j’ai eu l’info via un mail indépendant à votre service ! @FranceintheUK @francediplo

I'm happy I was not too close of this #fire: https://t.co/yHGDndDTET

[Matthieu Pommier @matpom45]

There is an impressive #fire with a huge #smoke plume at the moment in #Glasgow

@marinetondelier Je pense que vous vous trompez dans votre analyse. On peut etre sympathisant de gauche, etre écologiste, ne pas supporter la politique du gouvernement actuel, etre horrifé de la montée de l'extreme droite mais n'avoir aucune envie de votre pour LFI.

@AmirHSouri1 yeap, I've seen the same distribution in my AQ modelling

[Matthieu Pommier @matpom45]

We recently held a successful workshop in #AbuDhabi as part of our ongoing project with the Environment Agency – Abu Dhabi (EAD). During the workshop, we presented on a range of topics, including local #airquality, #meteorological modeling, and #regional air quality modelling.

[Matthieu Pommier @matpom45]

It was a real pleasure to present the progress of our project to @EADTweets and show the first outcomes of the #airquality study in #UAE during the stakeholders workshop. We had interesting discussions and hope this is just the first step in further fruitful #collaborations.
