Introducing the Vienna Urban Carbon Laboratory (VUCL)

<p>The Vienna Urban Carbon Laboratory (VUCL) has begun testing in situ measurement-based options for monitoring local carbon dioxide (CO<sub>2</sub>) and methane (CH<sub>4</sub>) emissions in Austria’s capital city. Building upon the groundwork of the CarboWien project, VUCL extends and expands the current tall-tower eddy covariance flux system and will furthermore conduct campaigns to measure carbon isotopes and isofluxes, as well as upwind-downwind gradients in total column CO<sub>2</sub> and CH<sub>4</sub> mixing ratios. The project, which runs between 2021 and 2024 and is funded by the Vienna Science and Technology Fund (WWTF), will be implemented by a collaboration between the University of Natural Resources and Life Sciences Vienna (BOKU), the Technical University of Munich (TUM), the Environment Agency Austria (EAA) and A1 Telekom Austria AG (A1). In addition to contributing to international research into measurement-based greenhouse gas emissions monitoring, the multi-method approach provides an opportunity to demonstrate measurement-based emissions monitoring options directly to Vienna’s civil servants responsible for climate change mitigation action in the city. Continuous local stakeholder engagement over the project duration is therefore planned.</p><p>This conference contribution to the WMO-IG3IS session at vEGU21 will allow VUCL to be introduced to relevant scientists and stakeholders in the international community. Given the recent project start (01 Feb 2021), the foreseen discussions on the project’s planned implementation will provide an important and timely input into VUCL. Finally, initial VUCL results will be presented together with data from the preceding CarboWien project (2018-2020) to show how the measured CO<sub>2</sub> fluxes in Vienna have been impacted by the lockdown restrictions due to the COVID-19 pandemic.</p>

Tall tower eddy covariance as a tool for evaluating climate change mitigation in Vienna, Austria

<p>The need for climate action in cities is becoming more and more critical. As such, systems that quantify local greenhouse gas (GHG) emissions to evaluate mitigation measures are growing in importance and are set to undergo increasing levels of scrutiny. Within the CarboWien project, the University of Natural Resources and Life Sciences, Vienna, the Environment Agency Austria and the telecommunications company A1 Telekom Austria AG are currently collaborating to investigate the potential of a tall tower eddy covariance station to support carbon dioxide (CO<sub>2</sub>) emissions monitoring in Vienna. Due to the tall tower approach (144 m measurement height) the measured turbulent fluxes are representative of net emissions from much of the city area. If maintained in the near- to medium‑term, this facility could provide an additional, independent instrument with which local climate change action can be continuously evaluated.</p><p>This conference contribution will present results from the measurement campaign so far (2018-2019). In addition to discussing the early-indicator function of these data and the scope for improving emissions inventories, the presentation will demonstrate how these measurements can be directly used to evaluate local mitigation measures. In particular, analyses of the 30-minute fluxes against local activity/proxy data will show how the performance of measures seeking to reduce CO<sub>2</sub> emissions from road traffic and space heating can be inferred.</p>

The evolution of an existing network to the new structure will require a phased migration strategy aimed at minimising capital expenditure during the transition phase, while reaping the benefits early on. Any action taken during this transition step should simplify the network's evolution to the NGN packet-switched architecture. This work conducted the study of the migration of PSTN networks to NGN Optical Fiber networks, its configuration and implementation of Smart AX MA5600T HUAWEI and C300M ZTE Shelfs MSANs solutions.
