Satellites can now find the sources of methane leaks

Some of these leaks are enormous. In the past few years one in particular made the news, at the Aliso Canyon gas storage facility managed by SoCal Gas[1]. It was the worst single natural gas leak for the U.S. in recorded history, with an estimated 97,100 tons of methane released.

Carbon Mapper is a really great mission that will help crack down on a lot of accidental and negligent releases of methane and CO2. I used to work on this project and there are some really amazing people making it happen: https://www.planet.com/pulse/carbon-mapper-launches-satellit...

They'll be blinded if they point it at the north east corridor. Just one example but NY/NJ/CT are sure to be just as bad

On a different subject... So Windy.com recently added some more data (click Additional Data/More Data on the side)

One of them is CO2.

In my heavily forested area it reads 79 PPBV. I'm confused because I've always thought we're in the 300-400 PPM for CO2. But if I got this right, 79 PPBV converted to ppm is .079ppm CO2... No? I was expecting a higher number. Something wrong about the V here in the number, volumetric meter I am assuming?

if you click around in the metro areas around the country it does read what I think is 200-400ppbv as expected.

Maybe somebody here can explain: What's the difference between ppbv and ppm?

I look forward to the data being made available. There is a lot of interest in identifying sources at high resolution.

I hope they comment here and give some sense of their roadmap and data subscription pricing.

How long until these satellites have enough precision to identify who farted?
