Why is summer ozone worsening in North China?
Atmospheric ridges trap heat and fuel ozone formation.
New research shows what drives them has shifted over the decades.

@jpschnitzler.netFresh smell after rain - #petrichor - is more than just a pleasant scent!
New research led by @andreaghirardo.bsky.social reveals that rewetting #dryland #soils triggers bursts of #VOCs, potentially contributing to #ozone and #aerosol formation.
@paulmac.bsky.social
@jpecol.bsky.socialThe study conducted a field experiment, using 13 winter #wheat (Triticum aestivum L.) cultivars, explored how stomatal traits and #leafstructure contribute to differences in #ozone sensitivity among cultivars.
![Heatmap analysis of O3 responsive traits in wheat cultivars. The heatmap illustrates the relative changes (%) of 13 winter wheat cultivars across 14 leaf traits under elevated ozone (E-O3) compared with ambient ozone (A-O3), calculated as (A-O3–E-O3)/A-O3 × 100. Rows represent cultivars, and columns represent individual traits, which are grouped into three functional categories: Anatomy (adaxial epidermis cell thickness, abaxial epidermis cell thickness, mesophyll tissue thickness, total leaf thickness), Physiology (leaf greenness, leaf dry mass, leaf area, LMA), and Stomatal traits [adaxial/abaxial stomatal density (SD), stomatal width (SW), and pore width (PW)]. Hierarchical clustering was applied to both cultivars and traits to visualize similarity patterns in O3 responsiveness. Negative values (blue) indicate trait increases under elevated O3, whereas positive values (red) denote reductions. Numbers inside each cell show the exact percentage change.](https://cdn.bsky.app/img/feed_fullsize/plain/did:plc:xlyx3rwuo5cyxjjbaiakv3bd/bafkreihkoqrclhdssa4me4ywjasghtpcj2pcxyv4acsemq6jyf2efgjljq@jpeg)
@andreaghirardo.bsky.socialHappy to share that our study on #Petrichor emissions is published in GCB. We showed that rewetting dryland soils triggers strong #VOC emissions with the potential to form #ozone and #aerosol.
Thanks to collagues and @dfg.de for their support!
@muser.press#Amazon wildfires may weaken the rainforest’s carbon uptake beyond their direct emissions. Modelling suggests #ozone formed from #wildfire emissions reduces carbon uptake by an amount equivalent to about 24% of the carbon released by the fires themselves. doi.org/rr8p

@joinclarity.bsky.social#VOCs come from many sources, including paint, cleaning products, traffic, and industry. Beyond direct health risks, they contribute to #ozone and PM2.5 formation. Continuous monitoring helps find hotspots and track mitigation efforts. tinyurl.com/5fup4n9t

@fiordaliso456.wsocial.euNot so good news from the European Environmental Agency for the red-orange Countries in this map. Half European population have been exposed tonpoor to very poor groud air quality in terms of #ozone.
The worst results in 2025 goes to Milan metropolitan area and Padana Plain
