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

Ozone–oxygen cycle (Biogeochemical cycle 🔄)

In 1930 Sydney Chapman resolved the chemistry involved. The process is commonly called the Chapman cycle by atmospheric scientists. Most of the ozone production occurs...

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.
