Digital Earth Ecological Lecture Hall Live Room
In ancient times, our ancestors had already consciously mastered the laws of cold, heat, and sunnyness, and compiled them into poems to recite. For example, in " Book of Songs ", "The rain and snow are gathered first, and then the snow is raised" and "From the west, and respect the rain is rising." The determination of the twenty-four solar terms further demonstrates the ancients' exploration in the field of meteorology and .
Nowadays, with the rapid development of science and technology, people do not need to rely on experience to predict the weather, but can also obtain accurate weather forecasts at any time, and can see the earth's ever-changing changes through meteorological satellite .
So, what unknown mysteries do meteorological satellites have? What responsibilities will meteorological satellites shoulder in the field of meteorological ecology? The second issue of the "Digital Earth Ecological Lecture Hall" sponsored by Zhongke Star Map will take you to unveil the "mystery" of meteorological technology.
focuses on small satellite , injecting "star" power into meteorological development
1 China Meteorological Administration former deputy director and president of China Meteorological Service Association Xu Xiaofeng, vice chairman and president of China Meteorological Services Association, Shao Zongyou , and Li Kun, general manager of Zhiyi Aerial (Beijing) Technology Co., Ltd., gathered in the live broadcast room to discuss meteorological science and technology innovation and development and explore new mysteries in the field of meteorological. This live broadcast is hosted by Fei Weiwei, vice president of Zhongke Star Map and senior vice president of Xingtu Weitianxin.
Theme Report
Theme Report session, meteorological expert Xu Xiaofeng explained the current status and prospects of global meteorological development based on the development process and new needs of meteorological satellites and the advantages and development prospects of small satellite .
Xu Xiaofeng proposed that although a seemingly complete global land-based and sea-based observation network has been built, it cannot meet the needs of global observation. "Only ground observation can be done once an hour, and ocean observation still cannot be observed once every three or even six hours. The ocean observation points are very dense, but the observation density is still not enough."
On April 28, 2022, the State Council issued the "Outline for High-Quality Development of Meteorology (2022-2035)", which clearly proposed to "strive to build a modern meteorological system with leading science and technology, precise monitoring, accurate forecasting, fine service, and satisfactory people..." How to achieve precise monitoring? Xu Xiaofeng believes that whether it is a large satellite or a ground observation, it is difficult to achieve higher precision time-space resolution observation. The advantages of small satellites are low in cost, short cycle, easy networking (same type), globalization, and targeted (a certain product), and have obvious advantages in improving the spatial and temporal resolution of single-element observations and filling detection gaps (constellations).
The coordinated development of the large satellite system and the small satellite constellation
What aspects do we need to start from to promote the development of meteorological small satellites? What roles can all parties " industry, education, research, " play? During the online dialogue session of the second issue of the "Digital Earth Ecological Lecture Hall", three experts, scholars and entrepreneurs, Xu Xiaofeng, Shao Zongyou and Li Kun, exchanged and discussed the "Prospects - See how small meteorological satellites show their skills".
Online Dialogue
Xu Xiaofeng proposed that from actual needs, to the possibility of technological development, to the application platform's processing of satellite data, every link can be handled well, so that small satellites and large satellites can complement each other and truly play an important role in business and scientific research. This is a complex systematic project that requires coordination between industry, academia and research parties.
Shao Zongyou analyzed in detail the current development status of the complementary development of large satellites and small satellites in an orderly manner.He believes that the large satellite has a large load and strong load, and conducts large-scale observations, while the small satellite conducts detailed inspections for a certain area or application to provide high-temporal and spatial resolution observation data.
GEOVIS digital earth developed by Zhongke Star Map combines the meteorological satellite observation system to empower meteorological and ecology industries and provide meteorological information engineering construction, meteorological data product release and meteorological solution capabilities in various industries. By connecting meteorological small satellite data, more accurate and more refined meteorological services can be provided.
In the field of commercial constellation construction, Li Kun proposed that the top-level design and planning of grassroots constellations should be strengthened to ensure that the constellations should start at a high level as a whole and avoid duplicate competition at low ends. At the same time, accelerate the research and development and innovation of key technologies to create an ecosystem of collaborative innovation for China's commercial meteorological small satellites.
digital earth empowers, providing strong support for meteorology
digital earth is a carrier platform for opening up satellite resources in the sky and industry applications on the ground. It has more significant advantages in promoting meteorology technological innovation and industrial applications. When the meteorological observation system combined with small satellite constellations and large satellite systems is built, what changes will it bring to our production and life? What support can the digital earth provide in this process?
Xu Xiaofeng believes that the cooperation between large and small satellites to conduct precision monitoring, thereby achieving seamless global observations, can enhance our global activity space, and at the same time, it can greatly assist the development of trade, tourism, fishery and other industries. In Shao Zongyou's view, the digital earth can provide certain calculations and computing power for meteorological forecast calculations. The high-quality development of meteorological conditions cannot be separated from the support of the digital earth, and Zhongke Star Map is a pioneer in the domestic digital earth industry. For meteorological, marine, ecological environment and other industries, Zhongke Star Map's newly developed GEOVIS+ meteorological application middle platform has introduced AI correction technology, and uses Beidou grid code-related technologies to transform existing data assimilation and meteorological numerical model modules to build a high-resolution customizable meteorological forecasting platform, which can quickly provide services including data production, meteorological forecasting and early warning, and meteorological product visualization to private and public domain users.
Zhongke Star Map's new generation meteorological forecasting system TAPES (Trans-scale Adaptive Prediction Enhanced System), can meet the masses and industries, meet the meteorological services of all walks of life, such as aviation, navigation, agriculture, sports events, energy, etc., and provide refined, personalized and customized meteorological services.
Interactive Q&A
In the final interactive Q&A session with the audience, three experts answered questions on the spot, and the audience had a deeper understanding of the role of meteorological satellites and digital earth in refined meteorological services.
