  • 11,000 Year Sunspot Number Reconstruction

    https://cmr.earthdata.nasa.gov/search/concepts/C1215197053-NOAA_NCEI.xml
    Description:

    From http://www.ncdc.noaa.gov/paleo/pubs/solanki2004/solanki2004.html Direct observations of sunspot numbers are available for the past four centuries, but longer time series are required, for example, for the identification of a possible solar influence on climate and for testing models of the solar dynamo. Here we report a reconstruction of the sunspot number covering the past 11,400 years, based on dendrochronologically dated radiocarbon concentrations. We combine physics-based models for each of the processes connecting the radiocarbon concentration with sunspot number. According to our reconstruction, the level of solar activity during the past 70 years is exceptional, and the previous period of equally high activity occurred more than 8,000 years ago. We find that during the past 11,400 years the Sun spent only of the order of 10% of the time at a similarly high level of magnetic activity and almost all of the earlier high-activity periods were shorter than the present episode. Although the rarity of the current episode of high average sunspot numbers may indicate that the Sun has contributed to the unusual climate change during the twentieth century, we point out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades. The series of reconstructed 10-yr averaged sunspot numbers with their 68% uncertainty. Years are given BP (before present), i.e. the calendar AD year, Yad, is related to the BP year, Ybp, as Yc=1950-Ybp. The tabulated years correspond to centers of the corresponding 10-year intervals. Negative values are artifacts and are consistent with zero within the error limits.

  • 15 year Wilhelm II Land MSA and HOOH shallow ice core record from Mount Brown South (MBS)

    https://cmr.earthdata.nasa.gov/search/concepts/C1214313640-AU_AADC.xml
    Description:

    This work presents results from a short firn core spanning 15 years collected from near Mount Brown, Wilhelm II Land, East Antarctica. Variations of methanesulphonic acid (MSA) at Mount Brown were positively correlated with sea-ice extent from the coastal region surrounding Mount Brown (60-1208 E) and from around the entire Antarctic coast (0-3608 E). Previous results from Law Dome identified this MSA-sea-ice relationship and proposed it as an Antarctic sea-ice proxy (Curran and others, 2003), with the strongest results found for the local Law Dome region. Our data provide supporting evidence for the Law Dome proxy (at another site in East Antarctica), but a deeper Mount Brown ice core is required to confirm the sea-ice decline suggested by Curran and others (2003). Results also indicate that this deeper record may also provide a more circum-Antarctic sea-ice proxy. This work was completed as part of ASAC project 757 (ASAC_757).

  • 150 year MSA sea ice proxy record from Law Dome, Antarctica

    https://cmr.earthdata.nasa.gov/search/concepts/C1214313532-AU_AADC.xml
    Description:

    This MSA record (1841-1995) is from a Law Dome ice core called "DSS" in East Antarctica. It was calibrated against satellite sea ice records and used to reconstruct sea ice extent prior to the satellite era. The following is taken from the abstract of the paper (Curran et al., 2003). The instrumental record of Antarctic sea ice in recent decades does not reveal a clear signature of warming despite observational evidence from coastal Antarctica. This work shows a significant correlation (P less than 0.002) between methanesulphonic acid (MSA) concentrations from a Law Dome ice core and 22 years of satellite-derived sea ice extent (SIE) for the 80 degrees E to 140 degrees E sector. Applying this instrumental calibration to longer term MSA data (1841 to 1995 A.D.) suggests that there has been a 20% decline in SIE since about 1950. The decline is not uniform, showing large cyclical variations, with periods of about 11 years, that confuse trend detection over the relatively short satellite era. This work was completed as part of ASAC project 757 (ASAC_757).

    Description:

    Generally referred to as August 31, 1886, as the earthquake occurred at 9:51 pm local time. Eight minutes later there was a severe aftershock. This was the most damaging earthquake to occur in the southeastern U.S. and one of the largest historic shocks in eastern North America. Structural damage was reported within several hundred kilometers from Charleston, and long-period effects were observed at distances exceeding 1,000 kilometers.
