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.
