Help meteorological disaster prevention and mitigation National Satellite Meteorological Center officially released the first application product of Fengyun 3 E star

On June 15, the National Satellite Meteorological Center officially released a series of ground application system products of Fengyun No. 3 (also known as "Dawn Star"). Products include more than ten species such as the wind farm measurement radar sea surface wind farm, sea ice monitoring, night light, GNOS hidden star wind farm, atmosphere, long wave radiation, land surface temperature, precipitation detection, solar image and space weather environment, which will further further Improve my country's weather forecast forecast, climate change response, meteorological disaster prevention and mitigation, and the level of ecological civilization.

Fengyun No. 3 E Star is the world's first weather satellite for civilian morning and dusk rails. It was successfully launched on July 5, 2021. The star is equipped with 11 valid loads including 3 new development instruments, filling the global numerical weather forecast model in the morning and dusk period. On June 1, 2022, Fengyun No. 3 E star and its ground application system transferred to business trial operation. Global observation data, effectively improving the accuracy and timeliness of global numerical weather forecasting, is of great significance to improving the global ground observation system.

The sun is the driving source of the changes in the weather and the space environment of the earth. Among the more than ten products applications in this batch, the X-EUVI extremely UV full-day image products can be used to monitor the phenomenon of a key impact on the crowns, activity areas, and Yao Bosomes on the space, which provides important space weather forecast and climate change monitoring. Scientific data.

In addition to monitoring the sun and improving my country's space weather forecasting and early warning level, a variety of products can also monitor the monitoring of various elements such as the earth's three -dimensional atmosphere, foreign facial wind farms, and night light at night, and enhance the capacity of weather and climate and atmospheric environment monitoring and analysis. For example, night lighting products can conduct high -resolution observations around the world, provide cloud, surface, and sea watch structure characteristics, which will not only help understand the development of urban economic development and air quality, but also monitor the forest fire and lightning at night. Special "equipment". In addition, products such as land surface temperature and sea watch temperature have important application value in terms of water conservancy agriculture and marine fisheries, respectively.

The application of Fengyun No. 3 E Star will further effectively support "global monitoring, global forecasting, global service", and play an important role in serving the "Belt and Road" construction. , Promoting the high -quality development of my country's meteorological cause played a positive role. According to the relevant person in charge, the next step will continue to promote the third batch of products to review, actively carry out quality inspection and evaluation, and continue to move towards the goal of "precision monitoring".
