If you're interested in how I quantified natural #CO2 emissions from "mofettes" near #Tübingen with a low-cost sensor network, and want to join my PhD defense tomorrow at 10:00, DM me here and i might send you the link (if I don't forget it 😅).
I'll be mostly talking about …

Quantification of natural CO2 emissions from mofettes using a low-cost sensor network at the Starzach site in South-West Germany
We present a top-down method to derive CO2 emissions from mofettes, using only point measurement time series at irregular locations. Notably, no wind vector information is needed, as gas transport is derived from cross-correlations between sensor stations and subsequently integrated using Gauss’ divergence theorem. The method is applied to an existing low-cost sensor network at the Starzach site near the Black Forest in Germany, for which no comprehensive estimate of the total emissions exist…

RE: mastodon.green/@gerrymcgovern/
New paper about local temperature impact of AI data centers:
The data heat island effect: quantifying the impact of AI data centers in a warming world

Diagram from the linked paper showing "Temperature increase through space as a function of the distance from the AI hyperscalers locations". "The aggregate average of the LST difference is shown in red solid line. The shaded areas show the interval between the maximum and minimum value of LST increase that has been recorded across the considered AI hyperscalers".

Car Dependency in Urban Accessibility
arxiv.org/abs/2604.01019

Car Dependency in Urban Accessibility
To achieve net-zero emissions, cities must transition away from reliance on private vehicles. However, car-centric urban growth has transformed the automobile from a convenience tool into a necessity for accessing essential services, creating significant "car dependency". This study introduces a novel Car Dependency Index (CDI) that quantifies the accessibility gap between private and public transport across 18 cities in Europe and North America. Utilising high-resolution geospatial data and nu…

And here is my published dissertation @…, about quantifying the natural CO2 exhaust at the Starzach site in Southwest Germany (my result: ~10t/d):
hdl.handle.net/10900/176213

Figure 2: Examples of CO2 degassing at the Starzach site. Figure reproduced from Büchau et al. (2022, Appendix A, page 62, kindly provided by the publisher under a CC-BY-4.0 license). (a) diffuse degassing, small ascending gas bubbles (during spring 2020 flooding), (b) mofette with largest diameter, examined in 2015 by Lübben and Leven (2022), (c) picture by Martin Schon in 2019, groundwater monitor well, turned into the site’s most active mofette shortly after its deployment in 2014.

Figure 5: Gas flow funnel system mounted over the groundwater monitoring well (Figure 1, installed in 2014, which turned into a mofette shortly after deployment) at the Starzach site in 2022. Figure reproduced from (Büchau et al., 2024a, Appendix B, page 80, licensed under CC-BY-4.0).
Figure 9: Flux-gradient setup close to the ground, next to the Starzach site’s mofette with the largest diameter (30 cm, Figure 2b, examined in 2015 by Lübben and Leven, 2022). Four Sensirion SCD30 low-cost CO2 sensors each are mounted 40 cm above and below a Campbell Scientific IRGASON eddy covariance station at 60 cm height. Measurements of this setup are shown in Figure 10 and Figure 11.
