What is the clearest resolution of meteorological data?

There are many data sources of historical data and forecast data in meteorological data websites, and the resolution of each data source is different.

Data source reference: and energy big data platform (xihe-energy.com) and digital source V 1.0.

Data introduction: Based on assimilation, revision and downscaling of several international authoritative meteorological inversion data sources and measured data of weather stations, an ultra-high precision data source independently developed.

Time analysis: 20 17 65438+ 10 ~ 20265438+0 February 3 1 day, every hour.

Spatial resolution: 30m grid, covering the whole territory of China.
