The ???? ??-???? monitoring platform takes a significant step forward with the Gas Flux Chamber, a key component designed for ??????-?????? ???????????? ?? ??₄ ??? ??₂. The ?????? ??????? ?????????, ????????? ?????? ??? ????? ??? ?????? ???????? team, led by ??. ???? ??? ?????? other partners, is pushing beyond the state-of-the-art by developing cost-efficient and robust Gas Flux Chambers that optimize capital cost, deployment, recovery, and maintenance. These innovations enable deployment in remote locations, improving geographical coverage and supporting long-term in-situ environmental observations.

By the end of 2024, AWI released the first prototype of gas flux chambers for accurate GHG measurements in hard-to-reach areas. In this prototype, ???????? (?????? ??????? and ??????? ?????????) contributed by optimizing the sensing module based on K96, while ???? (?????ø?? ??????) developed the motherboard for control, data acquisition, and communication. The prototype has already been tested in real conditions, with Figure 2 illustrating the gas flux chamber setup for ambient readings overnight in outdoor conditions. The image highlights temperature and pressure dynamics during the day-night cycle, with the reference analyzer placed in-line with the MISO sensor, causing a pressure decrease due to faster sample flow out of the temperature-controlled unit than in. With promising results, 10 assembled units of the MISO Gas Flux Chamber are now ready for deployment, supporting both manual and automated flux measurements. This advancement marks a significant step in enhancing greenhouse gas monitoring and expanding in-situ observation capabilities. Stay tuned for more updates!
