The weather forecast of each website is different. How did they come from?

Through meteorological satellites are: (different forecasts may lie in satellite quality)

① Shooting satellite cloud pictures.

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.
