Higher emissions of carbon dioxide, nitrous oxide, and methane during the daytime in two reservoirs - Biogeochemistry Greenhouse gas (GHG) emissions from reservoirs are quantitatively relevant for atmospheric climatic forcing. The magnitude of these fluxes depends on the mechanisms promoting the production of carbon ...

💡 It was while measuring the fluxes for this study (part of my PhD) that we noticed higher daytime N₂O emissions and decided to dig deeper…

That curiosity led to the discovery of #photochemodenitrification, a key process driving N₂O emissions

📄 www.science.org/doi/10.1126/...

🌍 Why it matters

Most GHG budgets use daytime-only data → risk of bias

📈 Ignoring diel cycles can overestimate or underestimate emissions

✅ Integrating 24h variability improves climate models & reservoir management

🌞 Sunlight drives photochemical N₂O and CO₂ production (#photochemodenitrification)

💨 Wind boosts gas exchange for all of them

⚠️ Reservoir drawdown triggers CH₄ bubbling (ebullition), with no specific diel pattern

#NitrousOxide #Methane #CarbonCycle #GHG

The diffusive fluxes (CO₂ N₂O and CH₄) showed strong daily synchrony

📊 How big is the difference?

Daytime emissions were on average:
☀️ CO₂: +159%
☀️ N₂O: +267%
☀️ CH₄ (diffusive): +194% vs. night

These short-term changes can rival seasonal variability!
#GHG #Climate #Reservoirs

🌞 Day vs Night matters for #GHG #emissions☀️

Our study shows daytime (diff) GHG emissions from #reservoirs far exceed nighttime levels

🔬Solar cycle (PhotoChem) + wind explain #N₂O & #CO₂ diel cycles; water management also matters for diff & ebull #CH₄ 🌊

@eleonpalmero.bsky.social thank you for visiting us and giving an excellent seminar!! bsky.app/profile/eleo...

Seminar poster containing the text Title: Photochemodenitrification Unveiled: Illuminating Aquatic Nitrous Oxide Production Abstract: Nitrous oxide (N2O) is a potent greenhouse gas and the main agent depleting stratospheric ozone. During the last decade, its atmospheric levels have risen faster than previously estimated, highlighting the need to better understand its sources. While microbial processes like ammonia oxidation and denitrification are known contributors, our recent research has uncovered a novel abiotic pathway-photochemodenitrification-where sunlight drives N20 production from nitrite in oxygen-rich surface fresh and marine waters. In addition, photochemodenitrification exceeded biological NOproduction in surface waters. Our latest findings reveal that this photochemical process also occurs in polar regions and the tropical open ocean, emphasizing its global distribution. Because it occurs in surface waters in direct contact with the atmosphere, photochemodenitrification holds the potential to contribute significantly to N20 emissions.

Excellent seminar talk today by Dr Elizabeth Leon-Palmero on her discovery of #photochemodenitrification & nitrous oxide production in aquatic systems.
