The Scientific Research Project on Marine Climate Change and Greenhouse Gas Monitoring, initiated by the Meteorological Bureau of Guangxi Zhuang Autonomous Region, is a key undertaking dedicated to the research of marine ecology and climate change in the region. The core components of the project include the construction of fixed monitoring stations for marine climate change and greenhouse gas monitoring stations, which are required to achieve ppb-level high-precision monitoring of greenhouse gases. This will provide critical data support for the study of marine climate change patterns and the accounting of greenhouse gas emissions.

As a large-scale scientific research project with an investment of tens of millions of yuan, it has brought together multiple research institutions and enterprises for collaborative participation. During the project implementation, Guoke Hanhai replaced cavity ring-down spectroscopy (CRDS) equipment with tunable diode laser absorption spectroscopy (TDLAS) technology-based devices. By utilizing less than 40% of the planned research funding, the project not only met the stringent high-precision requirements but also demonstrated superior adaptability to the complex and harsh environmental conditions of the marine and coastal areas—characterized by high humidity and severe salt spray corrosion—compared to CRDS equipment. This has ensured the long-term stability of the project’s monitoring operations.

Furthermore, the TDLAS solution that replaced CRDS technology has achieved a dual breakthrough in technical feasibility and economic rationality. The successful application of high-precision laser gas analyzers fully demonstrates the application value of our company’s products in major scientific research projects and complex harsh environments. It also provides a cost-effective and highly reliable technical solution reference for high-precision gas monitoring initiatives in the meteorological, marine, environmental protection and other related fields.
