Today is space with you [Issue 1400]
Last night, the Beijing Winter Olympics came to a perfect end
When you reminisce about the moments of the event
Don't forget
There used to be a special group of hardcore technology volunteers for the Winter Olympics
Contributed to the 24th Winter Olympics
They are called Fengyun satellites
Compared to the Summer Olympics
The Winter Olympics have more events to compete in the outdoors
Low temperatures, high wind speeds and poor visibility
All of these factors can lead to the postponement of the event
Accurate weather forecast at this time
This is especially important
The photo above is a group photo of the Fengyun satellite family
Among them, the Fengyun-4 satellite
It mainly conducts real-time dynamic monitoring of the development and evolution of atmospheric clouds
Fengyun-3 can do surface temperature, snow and other monitoring
All are information that the weather forecast is very concerned about
It is worth mentioning the Fengyun III A star
It's nicknamed "Olympic Star."
"Born" was made in May 2008
It was also the first satellite to serve the Olympics
During the 2008 Beijing Olympics
It has contributed to the protection of outdoor competitions such as equestrianism and sailing
14 years have passed
Fengyun III A-star has retired
This time, it is involved in the support mission of the Winter Olympics
It is the 8 wind stars in the family that are still in orbit
Patrol soldier "polar orbit satellite" Wind Cloud 3D that rotates non-stop every day
and the stationary "geostationary satellite" Fengyun 4A and Fengyun 4B
These three stars
It also served as the first-line main star of this Winter Olympics
Moving and static
Storm by storm
Catch wind and snow
Real-time monitoring of changes in the Weather System for the Winter Olympics
The fengyun-4 is equipped with a vertical detector
It is currently carried by an international geostationary satellite
The only vertical detector
It is currently in geostationary orbit at an altitude of 36,000 km
Only our Chinese Fengyun-4 satellite has this instrument installed
It can do a "three-dimensional CT" for the atmosphere.
By probing large temperature and humidity profile information that is difficult to capture
In addition, the fast imager on board the Fengyun 4B star
The maximum visible light resolution is 250 meters
Radiation imagers, interferometric infrared detectors, etc
Makes B-star accurate at a distance of 36,000 km
A temperature change of 0.05 degrees Celsius in the Earth's atmosphere is perceived
These are the "killer skills" of the B star of Fengyun Iv
Of course, each star has its own little "star" thoughts
Efforts are being made to record and collect meteorological data
Contribute to the Winter Olympics
Here, the little too want to say a word
"Weather Guards"
You've worked hard
