Chamber-based flux measurements for carbon dioxide, methane, nitrous oxide and other climate-active gases show high temporal and spatial variability and there is a need for autonomous, simple and affordable systems. The author present such a device that can be constructed for a few thousands euros/dollars. The Pondi logger will facilitate greenhouse gas studies in remote places and will be excellent tools to involve citizens in our climate studies.
Short summary
The Pondi is a cost-effective, lightweight logger designed for long-term monitoring of carbon dioxide, methane, and nitrous oxide emissions in both terrestrial and aquatic ecosystems. It addresses key challenges in greenhouse gas monitoring by providing an automated, low-cost, solar-powered solution with cloud connectivity and real-time analytics. Its robust design enables deployment in diverse environmental conditions, supporting large-scale, high-resolution emission assessments.
