The VSL model requires as inputs only latitude, monthly mean temperature, and monthly accumulated precipitation. Hence, this simple, process-based model enables ring-width simulation at any location where monthly climate records exist. In this study, we analyse the growth response of simulated tree rings to monthly climate conditions obtained from the CRU TS3.1 data set back to 1901. Our key aims are (a) to assess the VSL model performance by examining the relations between simulated and observed growth at 2287 globally distributed sites, (b) indentify optimal growth parameters found during the model calibration, and (c) to evaluate the potential of the VSL model as an observation operator for data-assimilation-based reconstructions of climate from tree-ring width. The assessment of the growth-onset threshold temperature of approximately 4–6 C for most sites and species using a Bayesian estimation approach complements other studies on the lower temperature limits where plant growth may be sustained. Our results suggest that the VSL model skilfully simulates site level treering series in response to climate forcing for a wide range of environmental conditions and species. Spatial aggregation of the tree-ring chronologies to reduce non-climatic noise at the site level yielded notable improvements in the coherence between modelled and actual growth. The resulting distinct and coherent patterns of significant relationships between the aggregated and simulated series further demonstrate the VSL model’s ability to skilfully capture the climatic signal contained in tree-ring series. Finally, we propose that the VSL model can be used as an observation operator in data assimilation approaches to reconstruct past climate. #-------------------- # Funding_Agency # Funding_Agency_Name: Swiss National Science Foundation # Grant: #-------------------- # Site_Information # Site_Name: Shchely Bozh # Location: # Country: Russia # Northernmost_Latitude: 66.22 # Southernmost_Latitude: 66.22 # Easternmost_Longitude: 56.33 # Westernmost_Longitude: 56.33 # Elevation: 65 m #-------------------- # Data_Collection # Collection_Name: asia_russ046wB # Earliest_Year: 1711 # Most_Recent_Year: 1990 # Time_Unit: y_ad # Core_Length: # Notes: {"sensitivity":"temperature"}{"T1":"6.56319741935"}{"T2":"18.9912259128"}{"M1":"0.0229272482091"}{"M2":"0.241068359961"} #-------------------- # Species # Species_Name: Scots pine # Species_Code: PISY #-------------------- # Chronology: # # # #-------------------- # Variables # # Data variables follow that are preceded by ## in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ##age age, , ,years AD, , , , ,N ##trsgi tree ring standardized growth index, tree ring, ,percent relative to mean growth, , Tree Rings, , ,N # #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: nan # age trsgi 1711 0.868 1712 0.916 1713 0.795 1714 0.602 1715 0.976 1716 0.784 1717 0.985 1718 1.099 1719 0.966 1720 1.069 1721 1.229 1722 0.742 1723 0.849 1724 0.913 1725 1.29 1726 1.292 1727 1.285 1728 1.322 1729 1.117 1730 0.63 1731 0.65 1732 0.611 1733 0.674 1734 0.646 1735 0.816 1736 0.916 1737 1.053 1738 1.047 1739 0.937 1740 0.726 1741 0.743 1742 0.687 1743 0.829 1744 1.019 1745 0.866 1746 0.505 1747 0.541 1748 0.533 1749 0.483 1750 0.687 1751 0.647 1752 0.479 1753 0.653 1754 0.646 1755 0.886 1756 1.175 1757 0.539 1758 0.592 1759 0.491 1760 0.509 1761 0.833 1762 1.06 1763 0.789 1764 1.311 1765 1.866 1766 1.407 1767 2.132 1768 1.973 1769 1.44 1770 0.823 1771 1.536 1772 1.516 1773 1.59 1774 2.494 1775 1.984 1776 1.275 1777 1.738 1778 1.96 1779 1.547 1780 1.843 1781 1.173 1782 1.514 1783 1.265 1784 0.973 1785 1.039 1786 0.62 1787 0.858 1788 0.822 1789 0.933 1790 1.236 1791 1.389 1792 1.274 1793 1.576 1794 1.549 1795 1.416 1796 1.55 1797 1.387 1798 1.23 1799 0.916 1800 1.319 1801 0.956 1802 0.934 1803 0.911 1804 0.874 1805 0.891 1806 0.825 1807 1.084 1808 1.129 1809 0.795 1810 0.527 1811 0.659 1812 0.733 1813 0.746 1814 0.58 1815 0.504 1816 0.326 1817 0.275 1818 0.342 1819 0.472 1820 0.537 1821 0.683 1822 0.765 1823 0.976 1824 0.938 1825 0.818 1826 0.801 1827 1.251 1828 0.825 1829 1.01 1830 1.456 1831 1.09 1832 1.227 1833 1.05 1834 0.752 1835 0.811 1836 0.796 1837 0.631 1838 0.513 1839 0.882 1840 0.894 1841 0.822 1842 1.1 1843 0.975 1844 1.411 1845 1.215 1846 1.258 1847 1.069 1848 1.139 1849 1.396 1850 1.434 1851 1.245 1852 1.187 1853 1.011 1854 1.09 1855 0.896 1856 1.122 1857 0.777 1858 0.583 1859 0.847 1860 0.827 1861 0.729 1862 0.562 1863 0.211 1864 0.719 1865 0.576 1866 0.684 1867 0.659 1868 0.607 1869 0.88 1870 1.1 1871 0.868 1872 0.701 1873 0.529 1874 0.853 1875 0.735 1876 0.823 1877 0.669 1878 0.779 1879 0.977 1880 0.842 1881 0.85 1882 0.614 1883 0.392 1884 0.718 1885 0.698 1886 0.763 1887 0.602 1888 0.663 1889 0.554 1890 0.788 1891 0.842 1892 0.271 1893 0.884 1894 0.694 1895 0.697 1896 0.769 1897 0.878 1898 1.245 1899 0.837 1900 0.94 1901 1.26 1902 1.331 1903 0.505 1904 0.979 1905 1.16 1906 1.192 1907 1.267 1908 1.244 1909 1.231 1910 0.94 1911 1.323 1912 1.043 1913 1.322 1914 0.97 1915 1.246 1916 1.203 1917 0.989 1918 0.967 1919 1.013 1920 0.845 1921 1.043 1922 1.397 1923 1.362 1924 1.416 1925 1.772 1926 1.307 1927 1.464 1928 1.493 1929 1.093 1930 1.368 1931 1.264 1932 1.312 1933 1.182 1934 1.332 1935 1.517 1936 1.583 1937 1.563 1938 1.568 1939 1.76 1940 1.771 1941 1.049 1942 1.081 1943 1.334 1944 1.329 1945 1.108 1946 1.067 1947 0.649 1948 0.88 1949 1.062 1950 0.933 1951 1.047 1952 1.256 1953 1.076 1954 1.39 1955 1.123 1956 1.298 1957 1.134 1958 0.91 1959 0.979 1960 1.047 1961 0.972 1962 0.838 1963 0.958 1964 1.221 1965 1.281 1966 1.054 1967 0.895 1968 0.893 1969 0.618 1970 0.739 1971 0.793 1972 0.727 1973 0.514 1974 0.547 1975 0.396 1976 0.572 1977 0.616 1978 0.666 1979 0.567 1980 0.674 1981 0.854 1982 0.524 1983 0.764 1984 0.816 1985 0.638 1986 0.646 1987 0.619 1988 0.83 1989 0.689 1990 0.694
