Supplemental Information | STUDY NOTES: Records of common production rate of cosmogenic radionuclides, cosmic ray intensity (solar modulation) and solar activity (total solar irradiance) during the past 9400 years. Common production rate (Figure 3), solar modulation (Figure S13) and total solar irradiance (Figure S14) during the past 9400 years. The records are based on several radionuclide records with high temporal resolution (years) from different sites and of different types (10Be from Antarctica and Greenland, 14C from tree rings). The data are 22-year averages. The common signal is the first principal component which was extracted with principal component analysis. These data are an update to Steinhilber et al. 2009 total solar irradiance data, also archived at the World Data Center for Paleoclimatology: https://www.ncei.noaa.gov/pub/data/paleo/climate_forcing/solar_variability/steinhilber2009tsi.txt ABSTRACT SUPPLIED BY ORIGINATOR: Understanding the temporal variation of cosmic radiation and solar activity during the Holocene is essential for studies of the solar-terrestrial relationship. Cosmic-ray produced radionuclides, such as 10Be and 14C which are stored in polar ice cores and tree rings, offer the unique opportunity to reconstruct the history of cosmic radiation and solar activity over many millennia. Although records from different archives basically agree, they also show some deviations during certain periods. So far most reconstructions were based on only one single radionuclide record, which makes detection and correction of these deviations impossible. Here we combine different 10Be ice core records from Greenland and Antarctica with the global 14C tree ring record using principal component analysis. This approach is only possible due to a new high-resolution 10Be record from Dronning Maud Land obtained within the European Project for Ice Coring in Antarctica in Antarctica. The new cosmic radiation record enables us to derive total solar irradiance, which is then used as a proxy of solar activity to identify the solar imprint in an Asian climate record. Though generally the agreement between solar forcing and Asian climate is good, there are also periods without any coherence, pointing to other forcings like volcanoes and greenhouse gases and their corresponding feedbacks. The newly derived records have the potential to improve our understanding of the solar dynamics and to quantify the solar influence on climate. |
