reconstructions (typically annually to seasonally resolved) have played a key role in understanding paleoclimate immediately prior to the beginning of the instrumental record, especially when calibrated to form an extension of comparable instrumental data coverage (global, hemispheric, and regional). Such calibration allows the information in the instrumental record to be quantitatively extended backward in time in an objective way, enabling description of much longer term fluctuations in climate than possible with instrumental data alone, although with significantly increased uncertainties inherent in proxy-based reconstructions. This data brief describes a newly integrated archive of nearly all the high-resolution temperature reconstructions of the past 2+ millennia included in NOAA's National Climatic Data Center, from small-regional to global scale, which also have been recalibrated to a standard set of instrumental data. Examination of the spectral structure of the data is additionally provided. STUDY NOTES: NOAA Paleoclimatology Paleoclimate Network (PCN) version 2.0.0, including 92 high-resolution temperature records over the past 2+ millennia, 1209 proxy data time series used by Mann et al. (2008, 2009), and instrumental data of the HadCRUT3 and HadCRUT3v combined global land and ocean gridded (5°x5°) surface temperature data sets, averaged to annual and seasonal time resolution by NOAA Paleoclimatology. The Reconstructions, Proxy, and Instrumental data sets are described in detail below. The RECONSTRUCTIONS include global, hemispheric, regional, and local reconstructions, generally with annual time-step resolution. The records come with many categories of metadata, including complete citations to original publications, seasonal period reconstructed (when applicable), anomaly period (if reconstructions are anomalies), latitude/longitude coverage, and URLs to the original NOAA Paleoclimate web pages from which the data were drawn. Each record is available as a separate ASCII file with fixed header and data formats, allowing machine reading of the data and time-step information. All the records together are also available in netCDF, ASCII, and Excel formats, including the complete metadata within the files themselves. The netCDF format version is provided in two files, the first with each record represented as a separate variable and the second as a time-by-study array in which each record is represented as a component of the study dimension. Sample scripts to open the netCDF versions in the R programming environment are also provided.
