Creator of Open-Meteo here. There is small tutorial to setup ERA5 locally: https://github.com/open-meteo/open-data/tree/main/tutorial_d... Under the hood Open-Meteo is using a custom file format with time-series chunking and specialised compression for low-frequency weather data. General purpose time-series databases do not even get close to this setup. |
