The article about quantifying natural #CO2 emissions from mofettes at the #Starzach site in Germany with a low-cost sensor network is published now at @plosclimate:

The results are that the investigated mofette field in #Starzach emits roughly three metric tonnes of CO2 per day (3000kg/d).
To put this into perspective: This 20x20m mofette field fills daily:
- a smaller hot air balloon with CO2 gas🎈
- or a small car (3m³) filled with liquid CO2 🚗
- or two #Minecraft blocks (2m³) of dry ice (solid CO2) 🧊🧊😮 And this study only looks at a couple of mofettes, there are more abandoned wells in the area...

In this¹ paper, I present a method to derive #CO2 movements and total emissions from cross-correlations between a bunch of CO2 stations (black arrows) at the #Starzach site near #Tübingen in south-western Germany. This site is known for its natural CO2 emissions from mofettes - holes in the ground where CO2 is emitted, sometimes as little geysers when water is involved.
More on the site in my previous publications²³.

Has anyone here published with @plosclimate?
My manuscript is slowly approaching submission state. It is a very technical paper about the essence of my #PhD: quantifying natural #CO2 emissions at the #Starzach site (Turns out, it's a few tonnes per day! 🤯)
Reading through the existing #PLOSClimate papers, mine seems a little too mathematical, but I guess it's fine? Typically one would submit this to AMT or JTECH but PLOS is a nonprofit, which I want to support.

My article @umphy Büchau et. al (2024) „A portable low-cost device to quantify advective gas fluxes from mofettes into the lower atmosphere: First application to Starzach mofettes (Germany)” is now available as #openAccess
https://doi.org/10.1007/s10661-023-12114-8
We built a partly #3dPrinted gas-channeling chimney with sensors (p, T, v̇, RH, #CO2), performed a thorough validation of all components and measured the CO2 degassing of a #mofette at the #Starzach site in southern #Germany.

Our article Büchau et. al (2024) „A portable low-cost device to quantify advective gas fluxes from mofettes into the lower atmosphere: First application to Starzach mofettes (Germany)” is now available as #openAccess

For this article, @nobodyinperson built a partly #3dPrinted hood with sensors (p, T, v̇, RH, #CO2), performed a thorough validation of all components and measured the degassing of a #mofette at the #Starzach site in southern #Germany.

I published a preprint of our manuscript about our low-cost device to measure advective gas fluxes from mofettes to @eartharxiv:
https://doi.org/10.31223/X5ZX0D
Our design involves #3dprinting, #ESP8266 and #FOSS. 🙂
The mofette we examined emits nearly 500kg of natural (magmatic, non-volcanic) CO₂ per day!

Gute Nachrichten aus meiner ehemaligen Heimatgemeinde #Starzach.
Dort soll ein #Windpark mit bis zu zehn Anlagen (voraussichtlich Vestas V172-7.2, Gesamthöhe 261m) entstehen:
https://www.tagblatt.de/Nachrichten/Oekostrom-fuer-25000-Familien-569882.htmlAuch ein paar Kilometer weiter bei Rottenburg-Seebronn scheint ein ähnliches Vorhaben auf gutem Weg zu sein und die üblichen Windkraftgegner mit ihren #Bürgerinitiativen scheinen weitestgehend ins Leere zu laufen.
Endlich geht's mit der #Windkraft in #BaWü voran!

Remembered I have this nice #moss picture taken in 2020 at the site I do CO₂ measurements at (https://doi.org/10.1127/metz/2022/1125) #mosstodon #photography #nature #naturephotography #Tübingen #Starzach #Neckartal #BadenWürttemberg
