Levoglucosan, a molecular tracer traditionally used to measure fine particulate matter (PM2.5) emissions from biomass burning, degrades chemically in the atmosphere significantly faster than previously assumed. Up to 88 percent of the compound is lost to volatilization and atmospheric degradation before it can be measured.

An Overdue Update: Giving Atmospheric Science Its Own Space

Atmospheric Science is the comprehensive study of the Earth's atmosphere, its physical and chemical processes, and the interactions between the atmosphere and other systems such as the hydrosphere, lithosphere, and biosphere.

The unprecedented surge in #atmospheric #methane during the early 2020s was primarily driven by a temporary decline in #hydroxyl (OH) radicals, which reduced the atmosphere's ability to break down the gas, coupled with increased natural emissions from wetlands due to wetter #climate conditions.

depends how hydrophilic it is. Some things, like sulfur trioxide, go after water vapor like a doberman on a pork chop (duh, those things are called "desiccants")

In that both HF and H2O hydrogen bond like crazy, I bet you'd need a low RH to stop this.

Now I'm wondering about water oligomers at say 70% RH. Water is a very sticky molecule, when you pull vacuum on a system pumping out the water is the first challenge.

Interesting discussion

I think I need to tag this

Looked around today, and the latest reported carbon dioxide atmospheric concentration is 422ppm. An online calculator converted this to a molar concentration of carbon dioxide of about 10 micromols. I found a graphic for carbon dioxide consumption in photosynthesis, the greatest sink for atmospheric carbon dioxide I could think of.

Like many biological processes substrate concentration determines the extent of reaction during any given amount of time, but there is an upper limit.
Also available photosynthetic light increases extent of reaction to an upper limit.

It seems carbon dioxide concentration and light both play a factor in determining the maximum rate of photosynthesis.

Does anyone have information on real world calculations of the maximum rate of photosynthesis?

A new study investigates the transport and removal processes of tropospheric ozone trace gas precursors in thunderstorms. Numerical simulations were performed to understand storm processes affecting atmospheric gases with different solubilities. doi.org/10.1029/2022JD037107 #atmosphericchemistry

This may help shed some daylight on why methane concentration is increasing faster than expected. Part of the explanation?

The OH radical is a key part of our atmospheric inventory, with ignorance of amount creating wider error bars than necessary in various prognostications. Should be on our dashboard, quantified. Here's a start! (preprint)

Interesting new study in @nature today - the observed #Methane spike in the atmosphere last year seems to relate to 2 elements:
1) - increased emissions from wetlands in a warmer + wetter climate (yes that's a positive feedback)
2) - reduction of NOx (Nitrogen pollution from cars + industry) due to #COVID19 lockdowns reduced the rate at which methane is removed from the atmosphere by chemistry.

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…

#introduction

Hi all! I'm an atmospheric chemist and professor at University of Minnesota. I study atmospheric trace gases and surface-atmosphere exchange using field measurements, modeling, and satellite-based remote sensing. Looking forward to conversations about those things and about science/academia more broadly. Also nerdy jokes. And anything about cycling, hockey, or coonhounds.

@arwhitehill @rachelOB1 @H_Herrmann24 @subu_caps So in my last post I tried to hashtag certain terms like #ChemicalEngineering and #AtmosphericChemistry wasn't able to (they didn't become links)... I see that I can here 🤔. Any ideas why?

Ok I just read the server rules so here's my #introduction @subu_caps!

I'm a professor at #Columbia University in #ChemicalEngineering and Earth and Environmental Sciences. My research is in #AtmosphericChemistry, #AirQuality (indoor and outdoor), #Aerosol Science. Atmospheric Chemistry Editor for #ACSEarthSpaceChem. VP of #AAAR. #IUPAC panel for atmos. chem. kinetic data evaluation. #ACS climate policy statement team. Formerly in elected positions in #AGU, #AIChE.

My #introduction --
I'm an #atmospheric and #analytical chemist, studying multiphase #chemistry on air-exposed surfaces.

My group at #Bucknell Univ. uses mass spectrometry (#TeamMassSpec), and we are looking to bring #ionmobility techniques more into the environmental chemistry realm.
