BigQuery Weather Public Data Sets - Missing Last Few Days Data

155 views Asked by At

I have run some queries against BigQuery public data sets for weather. I have used both GSOD (bigquery-public-data.noaa_gsod.gsod2019)and GHCN (bigquery-public-data.ghcn_d). In both cases, the most recent data I get is from 4 or 5 days ago. Why is that? What can I do to get more recent historic data e.g. this morning or yesterday by lat and long.

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.
