China Weather News March 23, 2024 is the 64th World Meteorological Day. The theme of this year's weather day is "At the Frontline of Climate Action". Global climate change is an increasingly serious problem, which has a profound impact on the earth's ecosystem. With more and more frequent extreme weather, global warming and climate crisis, global water shortage and other issues, climate and climate change issues continue to attract the attention of the international community. Governments, enterprises and individuals need to act together to actively take measures to slow down the development trend of climate change, while improving their ability to adapt to climate change.

Responsibilities of climate and climate change standardization

Article 32 of the Meteorology Law of the People's Republic of China stipulates that "the competent meteorological authority under the State Council shall be responsible for the comprehensive investigation and zoning of the country's climate resources, organize the climate monitoring, analysis and evaluation, monitor the atmospheric composition that may cause climate deterioration, and regularly issue the national climate status bulletin."

In order to promote the standardization of climate and climate change, the China Meteorological Administration actively applied to the National Standards Committee for the establishment of a standardization technical committee. In 2012, the National Technical Committee for Climate and Climate Change Standardization (SAC/TC 540) was established, and the Subcommittee on Atmospheric Composition Observation, Forecast and Early Warning Service (SC1) and the Subcommittee on Wind Energy and Solar Energy Climate Resources (SC2) were set up, which are mainly responsible for the preparation and revision of climate and climate change data acquisition and processing, diagnosis and prediction, impact assessment and climate monitoring indicators National and industrial standards for climate feasibility study, climate resource assessment, development and utilization, etc. Since its establishment, SAC/TC 540 has been actively promoting the formulation of national standards and meteorological industry standards on climate and climate change.

In order to strengthen the research on meteorological standardization, the China Meteorological Administration set up a national meteorological standardization research and technical support institution in the Meteorological Cadre Training Institute of the China Meteorological Administration in 2007, which is mainly responsible for the development strategy and basic research of meteorological standardization, standardization technical support and services. One of its responsibilities is to undertake the design and maintenance of the standard system. In recent years, the Meteorological Cadre Training Institute has carried out research on the framework of the standard system, including the climate and climate change standard system, and standard quality audit, which has strongly promoted the formulation of national standards and meteorological industry standards in this area.

Climate and climate change standard system

The climate and climate change standard system consists of 7 subsystems, including terminology, climate system detection, simulation and prediction, climate change response, climate and climate change impact, risk assessment, climate service and application, atmospheric composition observation, prediction and early warning service, wind and solar energy climate resources (see Figure 1). 159 standards have been formulated and issued, including 51 national standards 108 industry standards.

National strategies call for climate and climate change standards

In order to implement the major strategic decisions of the CPC Central Committee and the State Council on carbon peaking and carbon neutrality, and to further implement the National Standardization Development Outline, on April 22, 2023, the National Standards Commission, led by 11 departments including the China Meteorological Administration, jointly issued the Guidelines for the Construction of Carbon Peaking and Carbon Neutralization Standard System, Put forward the task of formulating and revising key standards closely related to climate and climate change, including standards such as carbon dioxide, methane and other greenhouse gas monitoring methods, monitoring equipment, online monitoring systems, wind energy resource monitoring, assessment and wind forecasting for wind power generation standards, solar energy resource monitoring, assessment and radiation forecasting for photovoltaic power generation standards, And solar thermal utilization standards such as solar normal direct radiation prediction. The implementation of these tasks requires the relevant units and technical organizations of the China Meteorological Administration to take further actions to strengthen the effective supply of standards.

In the national standards and meteorological industry standards led by the China Meteorological Administration, it has played an important role in the construction of national ecological civilization and the "double carbon" strategy. Among them, climate and climate change related standards have played an important leading role in the national response to climate change; The relevant national standards for greenhouse gas observation have become the reference for relevant industries and departments to carry out greenhouse gas observation. The industry and information technology field has also included them in the guide for the construction of the standard system, and some enterprises have also developed greenhouse gas observation equipment on this basis; Wind energy and solar energy related standards have served the national low-carbon, green and high-quality development. Protect our earth and home, protect the climate, and standardization work has been at the forefront to protect the climate action.
