What's the use of meteorological satellites?

The main observation contents of Baidu Encyclopedia meteorological satellite include: ① the shooting of satellite cloud images. ② Observe cloud top temperature, cloud top, cloud cover and condensation phase in the cloud. (3) Observation of land surface conditions, such as ice, snow and sand, and observation of ocean surface conditions, such as ocean surface temperature, sea ice and ocean currents. ④ The total amount of water vapor, humidity distribution, precipitation area and precipitation distribution in the atmosphere. ⑤ The content and distribution of ozone in the atmosphere. ⑥ The incident radiation of the sun, the total reflectivity of the earth-atmosphere system to solar radiation, and the infrared radiation of the earth-atmosphere system to space. ⑦ Monitoring space environmental conditions, such as the flux density of protons, alpha particles and electrons emitted by the sun. These observations help us to monitor the movement and evolution of the weather system; It provides a lot of basic data for studying climate change; It provides a large number of environmental monitoring results for space flight.

What is the function of meteorological satellites?

Meteorological satellites are mainly used for meteorological observation, such as judging where it is cloudy and where it is raining according to the movement of clouds. The main function of meteorological science is to detect clouds, water content and trends in the atmosphere, and it is one of the means to judge the future weather. Besides meteorological purposes, it can also be used in land resources, forest resources investigation, communication and military affairs.

What are the meteorological satellites, what are their functions and what are their pictures?

The names of meteorological satellites all begin with the word "Fengyun", such as "Fengyun No.1" and so on. Now, Fengyun -2 D is running in space. The main function of meteorological science is to detect the cloud and water content and trends in the atmosphere, and it is one of the means to judge the future weather. In addition to meteorological purposes, it can also be used for land resources, forest resources survey, communication and military.

What satellites are there and what are their functions?

According to the purpose:

Meteorological satellite: used to monitor the meteorological information of clouds and provide the latest meteorological situation and long-term meteorological analysis.

Military satellite: mainly used for military purposes and monitoring important military targets.

Communication satellite: mainly used for civil use, providing various communication purposes, such as TV broadcasting, IP communication network, telephone network, etc.

Resource satellite: mainly used for resource detection, etc.

Pass the track:

Low orbit satellite, medium orbit satellite, high orbit satellite, synchronous satellite, polar satellite, etc. , has a specific purpose and cannot pass according to different trajectories. For example, low-orbit satellites run at a relatively close distance from the earth and can be used for exploration, military, meteorology and so on. Synchronous satellites are located in synchronous orbit, relatively stationary with the earth, and are mainly used for civil purposes such as communication satellites and broadcasting.

In addition, it can be classified by volume, power and transponder frequency band.

What are the types and uses of satellites?

There are communication satellites, earth resources satellites, meteorological satellites, navigation satellites, reconnaissance satellites, broadcasting satellites, geodesic satellites, astronomical satellites and other scientific exploration satellites. Scientific exploration satellites are used to detect the physical environment in space, and their main tasks are to detect neutral particles, high-energy charged particles, solid particles, low-frequency electromagnetic waves and plasma waves, magnetic fields, electric fields and so on. Application satellite application satellite is an artificial earth satellite that directly serves the national economy and military affairs. According to the purpose, it can be divided into communication, meteorology, reconnaissance, navigation, geodesy, earth resources and multi-purpose satellites. Classification of communication satellites There are many kinds of communication satellites, which are divided into geostationary orbit communication satellites and flying geostationary orbit communication satellites according to their orbits. According to the purpose, there are broadcast and television direct broadcast satellites, tracking and data interruption satellites, maritime satellites and military communication satellites. Meteorological satellites Meteorological satellites can be divided into sun-synchronous orbit meteorological satellites and geostationary orbit meteorological satellites. Sun-synchronous orbit meteorological satellites patrol the earth's surface twice a day. Global meteorological data can be obtained. Geostationary meteorological satellites can continuously observe the global 1/3 area and send meteorological data back to the ground in real time. Resource satellite Resource satellite is a satellite used to survey and study the earth's resources. It can see through the stratum, find underground treasures, historical sites and stratum structure that people can't see with the naked eye, and can survey crops, forests, oceans, air and other resources. It can predict and identify the harvest of crops, and check and predict various natural disasters. Returning remote sensing satellite Returning satellite is a low-orbit satellite, which is mainly used for three purposes: observing the earth for a period of time and obtaining remote sensing information; The second is to conduct microgravity experiments; The third is the technical reserve for manned flight return. Reconnaissance satellite Reconnaissance satellite is an artificial earth satellite used to collect and intercept military information. The advantages of satellite reconnaissance are wide reconnaissance range and high speed, and it can monitor a certain area regularly or continuously without borders, which is of great significance to enhancing the country's military strength and comprehensive national strength. Reconnaissance satellites are distinguished according to the tasks they perform and the reconnaissance means they adopt. Generally divided into photographic reconnaissance satellites, electronic reconnaissance satellites, marine surveillance satellites and early warning satellites. The application of satellite in national economy uses recoverable satellite photos to dynamically monitor the 6000-square-kilometer Yellow River Delta. It is found that the Yellow River estuary has been silted 13 years and has extended to the sea for 33.5 kilometers.
