Add 8 countries to the atmospheric base station!How to get this step in the Meteorological Bureau?

New national atmosphere base station,

Not only the increase in quantity and the precision of observation layout,

It can also enhance the long -term observation of the key atmospheric component of service to see climate change.

It will help us better protect the ecology and achieve the "double carbon" goal.

The distribution map of the 16 climate system in my country

The reporter learned from the China Meteorological Administration that during the "14th Five -Year Plan" period, my country will be based on the existing 7 countries at the atmospheric base station and the upcoming Guangdong Xinfeng National Atmosphere. In other regional locations, 8 new countries are built at the atmosphere of the atmosphere to achieve the full coverage of the national atmospheric base station of 16 climate system key observations.

So, what is the atmospheric base station?

How is it layout? Look at it together!

What is it?

Atmospheric base station is the abbreviation of the atmospheric bottom monitoring station

The World Meteorological Organization is set in the world

Divided into the global atmospheric base station and regional atmospheric base station

Atmospheric Ben Under Station Observation

Reactive gases such as greenhouse gases and atmospheric ozone,

Qi -dissolved gum, solar radiation

Waiting for dozens of elements

The results of its observations are reflected

The larger scale atmosphere is not directly affected by artificial pollution

And the average status after mixing

Global Atmospheric Book Station

Site

Representative of large -scale site sites

It means that the space scale is generally thousands of kilometers

It should generally be located in remote cleaning areas

All directions around 30-50 kilometers around

In the next few decades

The land use condition does not change significantly

Observation content: The quality assurance and quality control (QA/QC) of the World Meteorological Organization Global Atmospheric Monitoring Plan (WMO GAW) requires the development of greenhouse gas, gas -soluble gum, reactive gas, total ozone, total acid rain and precipitation chemistry, radiation and other categories Full element coverage observation. In addition, there are some observations and research on extended elements.

Regional atmosphere base station

Site

Have good regional representativeness

It means that space scale is generally tens to hundreds of kilometers

But not with close -range transportation, industry and

A significant impact of pollution sources such as agriculture

Observation content: Refer to WMO GAW's content of the observation elements of the atmospheric base station on the regional atmosphere, and can strengthen observation of a certain type of elements according to the needs of the area. Encourage the content of all regions to expand its observation content to meet the multi -circle interaction of climate and multi -faceted application needs.

How to increase?

As one of the countries that developed atmospheric compliance, my country is one of the earliest observations of the atmosphere. At present, a global atmospheric base station has been built -Qinghai Wari Guan Global Atmospheric Book Station and Beijing Shangdianzi, Zhejiang Lin'an, Heilongjiang Longfengshan, Xinjiang Akdala, Yunnan Shangri -La, Hubei Jinsha This bottom station.

The monitor of the atmospheric monitoring department of Qinghai Wari Guan at the bottom station is conducting high -pressure gas distribution work

But this is not enough.

Combined with the observation requirements of the key observation area of the climate system, the China Meteorological Administration will comprehensive 8 comprehensives such as the Bohai Land and Sea gas, Huanghuai Farmland Ecology, Sichuan Basin Environment, Xilinule Grassland, Dunhuang Desert land surface process, Qinghai -Tibet Plateau land and atmosphere process The new national atmosphere station is added to the observation area.

"Fourteen Five -Year Plan" is the critical period and window period of carbon peaks.

In these eight key observations of the climate system that have not been carried out at the bottom of the atmosphere, the new national atmosphere station will be built in the key observation area, which will realize at least one national atmosphere station of each climate system key observation area. Such an additional location layout is based on the requirements of the China Meteorological Administration in accordance with the requirements of the implementation plan of the China Climate Observation System (CCOS), in accordance with the principles of traction, scientific and reasonable, long -term, and overall conservation.

In the opinion of Zhang Xiaoyu, an academician of the Chinese Academy of Engineering and researcher at the Chinese Academy of Meteorological Sciences, the construction of the Variguan Global Atmospheric Station not only promotes the local green and low -carbon development, but more importantly, the long -term scientific monitoring obtained through long -term scientific monitoring The "Variguan curve" has contributed consensus to the international community on the issue of climate change. It is of great significance to promote the world's reducing greenhouse gas emissions and actively responding to climate change.

How to determine the site?

The selection requirements of the atmosphere of the atmosphere are strict. Generally, they choose to "restore" the atmosphere of the atmosphere in areas that are far from human activities and pollution sources.

The China Meteorological Administration also clarifies specific requirements for the calculation analysis of the three -dimensional trajectory of the site, the remote sensing of the environment, the economic development and planning of the surrounding areas of the site, and the use of land use and infrastructure. The implementation group constituted by experts will invite some experts to guide the site to ensure the scientific and rigorous nature of the site screening and feasibility observation test.
