Application of Microwave Atmospheric Remote Sensing

Briefly explain how to use these things. The ocean used for ocean exploration accounts for 60% or more of the whole earth area. So now, in the last century, mankind mainly relied on land, with resources and food. The earth's non-renewable resources are getting less and less, oil exploitation is getting less and less, coal is getting less and less, food is getting more and more (because) the population is expanding. It is necessary to study the ocean. If you want to study the ocean, you need to study many dynamics of the ocean, such as long wave, long wave and wind, long wind speed, long temperature, how the sea surface temperature is distributed, and how the long ocean current and ocean current flow, because these things are closely related to human activities that people need.

For example, when you go out to sea, you must know the weather today, where the current goes and where the wind direction should go. Without this, he can't come back. In addition, marine animals, organisms and different kinds of fish are all related to the temperature of the ocean and the distribution of chlorophyll in the ocean. If you can master this thing accurately, fishermen can go there directly, so they can catch a lot of fish. The country uses this thing to guide marine fishing, which is the ocean. Then there are many disasters in the ocean, such as typhoons and El Nino. You have heard of abnormal temperature, and conversely La Nina is very close to human life. La Nina is the opposite of El Nino, which heats up and La Nina cools down. Then, if you don't understand this thing, why is the weather abnormal? Have something to do with this. I didn't know it in the past, so I can accurately predict it.

The continental shelf extends outward. The continental shelf is the territory of China. If you don't know how the continental shelf extends, you will talk less and suffer more. People laugh at you. This is the temperature of the sea surface. Temperature difference is very important. Just now, I gave a simple example, the problem of fishing. In addition, the El Ni? o phenomenon is detected by the temperature and height changes of the ocean. The atmosphere is very concerned. The ocean atmosphere is in space, so you must make a prediction about the precipitation, rainfall and snowfall in the atmosphere. If you want to make a forecast, you need to know the cloud, the water content of the cloud and the particle size of water. Generally speaking, clouds don't rain. When you master this knowledge, it will rain a little more. Therefore, atmospheric exploration is very important to human beings. The weather forecast depends on this thing, and remote sensing gives these data more accurate.

Below is the land, where people live. Land use is mainly the distribution of vegetation and sandstorm. Isn't it serious desertification? Remote sensing plays a role here. Where is this trachoma? Where did you say the acid rain came from? In addition, human beings now have food, clothing, housing and transportation, as well as annual crop yield estimation. This is very important for the development of the national economy. Why does the State Planning Commission wait until the end of the year to hold next year's planning meeting? Sometimes the meeting can't be held at the end of the year, and the next year's meeting will be held in June+10, 5438, waiting for the rate of return forecast to be accurate. Some things can be exported, while others adjust the variety and import quantity of grain. If we can't grasp this point, the export of the export and the import that should not be imported must stop. Therefore, the accuracy of agricultural yield estimation is 95%, and the accuracy of rice yield estimation is about 85% lower.

Another earthquake, earthquake prediction is a difficult problem in the world, and there is no good way at present, but by using these space technologies and geological technologies, microwave atmospheric remote sensing has gradually improved and its ability to predict earthquakes has become stronger and stronger. Remote sensing here mainly looks at the temperature changes on the ground from the air, including infrared and microwave. Another prospecting, there are many oil fields underground, how to find out the best way to drill wells. But you can't drill wells everywhere. Where to drill holes is more accurate, which saves a lot of money and manpower. This remote sensing technology provides this information. There may be oil in this direction. Go and fight.
