To download ISCCP global, 3-hourly HGG weather state (WS) data in netCDF form, click here. The dataset is at 1-degree horizontal resolution, it currently (as of May 2021) covers the period from July 1983 to June 2017. It will be updated as the HGG dataset is expanded.
After downloading the HGG WS data, refer to the
README.txt file for a detailed description of the data,
the H1.py script for an example of using the data in Python, and H1.ipynb (requires jupyter notebook) for an interactive version of H1.py.
