### Dataset Summary

This dataset consists of various sets of historical operational GFS forecasts, and analysis files from 2016-2022. The analysis files and forecasts are initialized at 00, 06, 12, and 18 UTC every day and ran for multiple hours. Additionally, raw observations are also included, which are the observations that are used to initialize the analysis and forecasts. The dataset is being expanded over time as more historical data is processed, and more observations as well.

The `data/forecasts/GFSv16/` folder holds the historical operational forecasts out to 48 hours from initialization, on all pressure levels, and for all variables that are present in every timestep (so not any accumulated values). The data is all stored as zipped Zarr stores, openable by xarray.
