Decentralized sharing and application of meteorological data

2. It should be like this, but there is another problem. This is the rainfall from 20:00 to 20:00, so it is from 8:00 p.m. that day to 8:00 p.m. the next day, mainly the rainfall of the second day, but the time point is the first day. In this case, will it be a day away from the actual rainfall

3. This is a problem with their server. It has nothing to do with you. It may be under maintenance

With the improvement of the role of meteorological data in social development, the demand for meteorological data from all walks of life is more and more urgent, and the requirements are also higher and higher. Meteorological data sharing service must face the market and all walks of life in order to have stronger vitality

(1) standardization of meteorological data information management and service

socialist market economy has standardization requirements for all walks of life. The management and service of meteorological data also need a complete standard system to support, in order to better complete its social tasks

the service standardization of meteorological data management and service should penetrate into all aspects of meteorological work, including public meteorology, safety meteorology and resource meteorology. The two core tasks of meteorological department: disaster prevention and mitigation and climate change are inseparable from the support of standardization. Only through standardized specification and standardized system can we better apply meteorological data procts and services, and provide support for disaster prevention and mitigation and response to climate change. In April 2009, the China Meteorological Administration organized the compilation of the National Meteorological standard system construction and standardization development plan from 2009 to 2011, which determined the goals and key tasks of meteorological standardization development in the next three years. Therefore, the standardization of meteorological data management and service is the general trend

(2) commercialization and marketization of meteorological data information management and service, We should graally promote commercial paid professional services. The National Meteorological Administration, in consultation with relevant departments, has formulated specific measures for carrying out paid professional services. On March 29, 1985, the general office of the State Council issued a notice transmitting the report on paid service and comprehensive operation of meteorological departments issued by the State Meteorological Administration (GBF No. 25 document), which aroused the enthusiasm of meteorological staff to carry out meteorological services, expanded the field of meteorological services, and had a far-reaching impact on the development of meteorological undertakings. The commercialization of meteorological data is inevitable. This requires the meteorological data sharing services need to introce market competition, the national meteorological departments and private meteorological companies have commercial paid services, fair competition, to improve the level of meteorological data sharing management and service

5. Some data need to be authenticated before you can search and download

6. Climate is a part of the natural environment and the most important environmental condition for human activities. At present, climate change and extreme weather and climate events are threatening the social and economic development and the safety of people's lives and property in the world, seriously affecting the realization of the strategic goal of global sustainable development. Maintaining the balance of the climate system and coordinating the relationship between man and nature has become one of the major issues of great concern in the world today. The meteorological scientific data describing the state and characteristics of the atmosphere and its related spheres is not only the research basis of climate system related disciplines, but also the indispensable important information of national economic construction, social development, national defense construction, environmental protection, ecological construction and people's life

scientific data is the basic data and information proced by the scientific and technological activities of human society, as well as the data procts and related information processed systematically according to different needs. It has obvious potential value and exploitable value, and can be added in the process of wide application. It is the most basic, active and influential scientific and technological information resource in the information age. To carry out scientific data sharing is not only the urgent need of contemporary scientific and technological innovation and development, but also an important basic support for the coordinated and sustainable development of economy and society

meteorological scientific data has been listed as the first batch of pilot projects of national scientific data sharing project for its wide application needs and good business foundation. The following is a brief introction of the progress and future development of meteorological science data sharing in recent years< In China, meteorological data is one of the longest, most complete and most systematic earth information resources. Due to its special geographical location and diversity of natural conditions, especially the unique condition of rich human and natural records, China has attracted much attention from the international academic circles. Through years of construction and development, China's meteorological department has formed a ground-based and air-based atmospheric and related environmental detection system. It includes conventional ground, high altitude, radiation, acid rain, agrometeorological observation, atmospheric background observation stations and many other special observation stations. In addition, we have established two long-term observation stations in Antarctica, Zhongshan and the Great Wall

at present, China is one of the few countries in the world that have both polar orbiting and geostationary meteorological satellites. The two operational satellites complement each other in time and space, and can continuously obtain massive atmospheric environmental information of all-weather and global spectrum. Relying on FY-1 and FY-2 Meteorological satellite application system engineering construction, China Meteorological Administration has established the most complete satellite data receiving application system in China. It has received and preserved the data of FY-1, NOAA, FY-2, GMS, Meteosat, EOS and other domestic and foreign meteorological satellites and earth environment monitoring satellites<

at present, China is setting up a new generation of weather radar monitoring network along the coastline, rivers, lakes and inland important cities. The data obtained by the network will not only significantly improve the ability of short-term weather forecast, but also play an important role in the fields of ecological monitoring, aviation support and disaster prevention and rection

in order to further improve the ability of sandstorm monitoring and early warning in China, 15 meteorological stations are equipped with soil moisture monitoring instruments, 20 stations are equipped with band solar photometer, 15 stations are equipped with atmospheric thermal infrared radiometer, 10 stations are equipped with atmospheric visibility meter, and 15 stations are equipped with instruments to measure the mass concentration of atmospheric suspended particulate matter and atmospheric st, 15 stations are equipped with meteorological gradient observation towers, etc. The soil moisture, vegetation status, boundary layer parameters, aerosol physical and chemical characteristics and their spatial distribution on underlying surface which affect the occurrence and development of sandstorm were quantitatively monitored

after long-term accumulation, China Meteorological Administration has a large number of preliminary standardized climate system observation data. At present, the data stock has exceeded 100TB. In the future, with the construction and operation of the new generation Doppler weather radar, meteorological and environmental satellite and new automatic observation station network, the annual data increment will exceed 200tb

as a data sharing business support environment, China Meteorological Administration has a relatively complete meteorological information network communication system, which is one of the regional centers of the global meteorological communication system (GTS) of the World Meteorological Organization (WMO). The meteorological information network system of China Meteorological Administration (9210) which has been put into operation has constituted a real-time collection, transmission and distribution system of meteorological data and procts at national, provincial, prefectural and county levels; The global meteorological communication system network managed by the World Meteorological Organization (WMO) and participated by countries all over the world can exchange data and distribute data procts in real time<

China Meteorological Administration (CMA) processes a large number of meteorological data every day with a supercomputer system. The national North High Performance Computing Center is located in the National Meteorological Information Center of China Meteorological Administration. It has domestic Shenwei, Yinhe, dawning, IBM, Cray and other supercomputers, providing reliable hardware facilities for data sharing. At present, the construction of national meteorological data storage and retrieval system and Fengyun 02 batch of ground application system are being implemented, which can provide efficient business system and massive storage environment support for the collection, processing, storage and service of various meteorological data< As a member of the World Meteorological Organization (WMO), China has extensive meteorological cooperation and exchange of meteorological data and procts with the international community. In 1980, we joined the global meteorological communication system. Tens of thousands of meteorological reports are transmitted to countries all over the world every day, providing services for weather forecast, disaster early warning and operational scientific research all over the world. At the same time, in accordance with the spirit of WMO resolution 40, China actively provides basic long-term historical data to participate in international exchanges. We have established a good cooperative relationship with data institutions in many countries in the world. In China, as early as the 1980s, the China Meteorological Administration (CMA) transmitted real-time meteorological data to the general staff, air Department, civil aviation, water conservancy, oceanography, Institute of Atmospheric Physics, Chinese Academy of Sciences, Peking University and other relevant departments and units through the same city user terminal. The meteorological satellite data we receive are also broadcast to all users< In December 2001, with the support of the Ministry of science and technology, China Meteorological Administration (CMA) issued the measures for the management of meteorological data sharing, and began to implement the pilot work of meteorological scientific data sharing, providing public welfare sharing services for users in various fields through various forms such as network and media . In order to cooperate with the development of meteorological scientific data sharing and continuously enhance the ability of sharing services, the Ministry of science and technology has issued the "construction of meteorological data sharing system" project to carry out research and development in three aspects of data resource integration, technical standard guarantee and sharing service platform; At the same time, China Meteorological Administration has also integrated internal resources and opened service platforms such as "satellite data sharing service website". After more than two years of construction, we have completed the research and development of 68 kinds of data set procts in 13 categories, including ground, high altitude, ocean ships, satellite remote sensing, etc., with a total data volume of 740gb; A number of urgently needed data standards and technical schemes, such as "meteorological scientific data classification specification", "meteorological scientific data metadata standard", "meteorological data sharing service implementation rules", have been developed; A distributed shared service network composed of one main node and eight sub nodes has been built initially. The total amount of data available for download on the Internet exceeds 100GB, providing users with various online retrieval and data download services

in the past three years, China Meteorological Administration has provided a large number of offline and online meteorological data sharing services for public welfare users. According to statistics, from January 2002 to March 2004, the National Meteorological Archives provided 627 visits to users in scientific research, government decision-making, national major engineering construction, national defense and other fields, with a total amount of 430gb data; Shared services website http://cdc.cma.gov.cn More than 120000 visits, 218 new registered users, and more than 500GB of data downloaded online

in order to ensure the continuous and in-depth development of meteorological scientific data sharing, the most important thing is to establish a set of management and operation mechanism concive to sharing. In the practice of sharing pilot, we mainly strengthen the sharing system from the following three aspects

first, from the national height, we should formulate "meteorological data sharing management measures" to provide policy guidance and implementation basis for data sharing

to carry out sharing, policy first. In the preparatory stage of the sharing pilot, China Meteorological Administration attached great importance to the formulation of departmental policies. According to the legal principles of the meteorological law and the relevant WMO data exchange policies, it formulated and promulgated the management measures for the sharing of meteorological data, which not only provided laws and regulations for the sharing of meteorological scientific data, It also provides an effective guarantee for the rapid start and sustainable development of this work

Second, we should make overall planning, make breakthroughs in key areas, and actively and steadily promote the sharing work in accordance with the principle of classification<

meteorological scientific data has a wide range, a wide variety and a great difference in basis. In order to rapidly carry out public welfare meteorological scientific data sharing service, we must face the urgent need and based on the reality, choose better basic conventional observation data and real-time satellite meteorological data to provide services. At the same time, we try our best to organize the research and development of new data sets to provide users with more and better meteorological scientific data procts

thirdly, we should strengthen management, pay attention to standards, and establish a professional operation mechanism. At the beginning of sharing, the China Meteorological Administration clearly required data management units at all levels to include sharing services into their annual work assessment objectives, to include data sharing into normal business proceres for standardized management, assessment and evaluation, to ensure the healthy and sustainable development of their work, and to promote the integration of sharing work with the planning and construction of meteorological information system, so as to form a scientific, reasonable and effective system Smooth information system< Third, the idea of further promoting meteorological data sharing

although meteorological data sharing has taken the first step and made some achievements, there is still a big gap between the national and social demand for meteorological data sharing. At present, only some conventional elements and real-time data with good foundation can provide sharing services, The overall benefit of meteorological scientific data is far from being brought into full play. In order to further deepen the work of meteorological data sharing, build a meteorological data sharing network system and a sustainable and stable operation mechanism in the whole field, we need to promote scientific data sharing in a larger scope and at a deeper level, In the future, we will make more solid efforts in the following four aspects

1. Give full play to the benefits of modernization construction, continuously enhance the level and ability of sharing services, and provide more and better services for national development and social progress< At present and in the next few years, the construction of meteorological modernization is booming,

7. You need to register users, and then send a query. Note that users are classified, some can download, and some can download only after users upgrade

8. What satellite data do you need? You don't have to download it from China Meteorological science data sharing website. The openness of China's satellite data is too poor. Can you tell me what kind of satellite data you need and where you can get to
in this way?

9.

According to reports, meteorological experts recently said that up to now, China has successfully launched 15 FY satellites, of which 8 are in orbit. Before FY-4, there were more than 2500 domestic users of FY-4, which effectively guaranteed the application needs of disaster prevention and mitigation, climate change and ecological environment protection. China's meteorological satellite data sharing has reached the forefront of the world

According to experts, the data of China's FY-1, FY-2 and FY-3 are also open to the world, and China's meteorological satellite data is the best to be shared domestically and internationally

10. Yes, that's how I was cheated for more than 100000 yuan. I just got it back. You can do that, too
