Surface temperatures drive strong seasonality in urban reactive carbon emissions
Urban air quality is affected by diverse volatile organic compounds (VOCs), and prior studies reveal a need to understand their seasonal sources. We combine high-resolution mass spectrometry with eddy...

Since I did do my PhD in cyanobacteria growth and treatment optimization modeling AND work in the water treatment industry, I’m gonna share my theory as to what’s happening here and how to fix it. People are focusing on the painted bottom of the pool increasing residual heat, and while that 1/19

Ha ha. That's a malfunctioning sensor. It's been reading ridiculous numbers for a while if you look at the time series. But the Marine Polar Lab is in a hollow that has a pretty strong local temperature inversion that traps emissions from cars, the natural gas boiler and the sewer pump.

But what do they think will happen when less light comes to the surface (even if it's diffuse)? Less OH = longer methane, etc lifetimes. Already stressed ecosystems could just give up trying to grow (less CO2 uptake). The lack of earth science knowledge expressed by the company here is terrifying!

I don't use X. But just be careful until it's confirmed. There was a PNAS paper that (I'm summarizing) incorrectly claimed there was a large methane pluse in Siberia when it was a hot rock throwing off the albedo in the retrieval. So there is a history of problems there.

@mparrington.bsky.social Do you know what observations are driving this large methane increase in CAMS? Is it TropOMI? Or is it a tower?
200
Róisín Commane @roseatmos.bsky.social · 01/09/2025
Is that CAMS methane model using TropOMI satellite data? The satellite could predict an increase that is not real before/after a fire when the surface characteristics change. You might want to check that anyone on the ground is seeing an increase.

What comes out of a stack depends on what you burn (coal much worse than natural gas) and whether or not any scrubbing technology is employed (we routinely scrub out NOx, SOx and mercury).
