Abstract In-Situ data acquisition of high-resolution nitrate concentration in Antarctic snow resulting from ionization in the polar atmosphere reveals (a) very large solar proton events can be resolved, (b) a signal from thermospheric and mesospheric sources is found across Antarctica within the average boundaries of the auroral oval, (c) long-term periods of high or low solar activity, such as the Maunder Minimum are present in the nitrate record.
