Surface Carbon Verification Technical Regulations

1 Scope

GB/T 42419-2023 covers the technical procedure for verifying carbon at the earth's surface. It lays out the overall process and its requirements, what is taken as the object of the check and how the verification result is expressed, then the observation and simulation of carbon storage in terrestrial ecosystems from surface data and from remote sensing data, and then the ground and remote sensing observation used for atmospheric XCO2. Appendix A gives an input data format example for HASM and other methods, Appendix B deals with extracting attribute information from carbon satellites, and Appendix C with the atmospheric chemical transport model and the pressure weighting function. The document applies to verification of living carbon in terrestrial plants and of atmospheric XCO2 using ground observation data and remote sensing imagery. Carbon accounting only means anything if two teams measuring the same forest or the same air column arrive at comparable answers, and ground plots, satellite retrievals and model output each carry their own conventions; without a written procedure fixing what is checked, which data are combined and how the result is reported, a verification cannot be audited or repeated. The introduction records that 6.3 and 7.3 involve a patented surface modelling method. Written for the institutes and consultancies that perform carbon verification and for the authorities receiving their results.

This document specifies the overall process and requirements for surface carbon verification, terrestrial ecosystem carbon storage observation and simulation, and atmospheric XCO2 data observation.

The corresponding verification methods are described.

This document is applicable to the living carbon verification of terrestrial plants and atmospheric XCO2 carbon verification using ground observation data and remote sensing image data.

It is suitable for carbon verification of soil, ocean and artificial ecosystems. Estimation of terrestrial ecosystem biomass, carbon storage, and

XCO2, etc. can be used for reference.
