At present, the most detailed meteorological data in the world can be traced back to the Republic of China, and the global annual/monthly/daily/hourly meteorological data can be obtained free of charge. 190 1-2020. As shown in the figure, the red thumbtack on the map represents the meteorological observation station. Click any site to get the latitude and longitude information of the site, and click OK to retrieve the meteorological data of the site. Considering that many weather stations have been demolished and built, there were not so many weather stations as early as the fifties and sixties. So generally speaking, we will first check the data year by year, then check the corresponding monthly data according to the year that the site can provide, and finally refine it to the daily/hourly data, depending on the actual situation.

Meteorological data preview

In fact, we are more concerned about the accuracy of meteorological data, so we will find different data columns in the system, such as measured data, grid data, yearbook data and so on. They come from different sources. The measured data is the ground observation data of NOAA, the grid is the satellite inversion product of NASA, and the yearbook data released by the National Bureau of Statistics is equivalent to a standard reference. For example, the precipitation in the same area, the data obtained by different columns will be more or less different. In fact, this is good for data analysis and scientific research. The comparison of multi-channel data can provide us with more reference.
