我已经针对 BigQuery 公共数据集运行了一些天气查询。我同时使用了 GSOD ( bigquery-public-data.noaa_gsod.gsod2019) 和 GHCN (bigquery-public-data.ghcn_d)。在这两种情况下,我获得的最新数据都是 4 或 5 天前的数据。这是为什么?我可以做些什么来获取最近的历史数据,例如今天早上或昨天的纬度和经度。

Those historical datasets are provided by NOAA a few days delayed. For real-time weather, you have to use one of the commercial weather data providers in the Marketplace.
