Reconstructed Dataset for Solar Proxies i.e. F10.7, S10.7, Y10.7, M10.7 back to 1800s.

The dataset contains key indicators of solar magnetic activity, including sunspot number, sunspot area, and solar plage area, together with the solar proxy indices F10.7, S10.7, Y10.7, and M10.7, as well as their corresponding 81-day running averages. The proxy indices were reconstructed using a hybrid machine learning model, extending continuously from 1826 onward and overlapping with the period of observed values.
