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: Babler State Park # Location: # Country: United States # Northernmost_Latitude: 38.6 # Southernmost_Latitude: 38.6 # Easternmost_Longitude: -90.72 # Westernmost_Longitude: -90.72 # Elevation: 210 m #-------------------- # Data_Collection # Collection_Name: northamerica_usa_mo014B # Earliest_Year: 1715 # Most_Recent_Year: 1980 # Time_Unit: y_ad # Core_Length: # Notes: {"sensitivity":"moisture"}{"T1":"5.060403238"}{"T2":"17.8963393592"}{"M1":"0.0222499545171"}{"M2":"0.552165065308"} #-------------------- # Species # Species_Name: white oak # Species_Code: QUAL #-------------------- # 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 1715 0.924 1716 0.956 1717 1.02 1718 0.922 1719 0.971 1720 0.825 1721 0.572 1722 0.668 1723 0.637 1724 0.499 1725 0.82 1726 0.821 1727 0.78 1728 0.701 1729 0.964 1730 0.98 1731 0.73 1732 0.837 1733 0.921 1734 0.763 1735 0.575 1736 0.408 1737 0.713 1738 0.832 1739 0.898 1740 1.107 1741 0.921 1742 0.911 1743 0.829 1744 0.975 1745 0.985 1746 0.613 1747 0.94 1748 0.774 1749 0.633 1750 1.014 1751 0.834 1752 0.817 1753 0.653 1754 0.779 1755 0.888 1756 1.254 1757 0.776 1758 0.909 1759 1.505 1760 1.238 1761 1.113 1762 0.88 1763 1.091 1764 1.256 1765 1.209 1766 1.3 1767 0.833 1768 1.277 1769 1.314 1770 0.946 1771 0.935 1772 0.691 1773 0.6 1774 0.624 1775 0.958 1776 1.011 1777 0.881 1778 1.058 1779 1.186 1780 1.128 1781 1.221 1782 1.218 1783 1.059 1784 1.004 1785 1.033 1786 0.987 1787 1.122 1788 1.055 1789 0.745 1790 0.715 1791 1.031 1792 0.879 1793 0.89 1794 0.854 1795 0.76 1796 0.982 1797 1.083 1798 0.87 1799 0.679 1800 0.648 1801 0.685 1802 0.944 1803 0.779 1804 0.831 1805 0.866 1806 0.774 1807 0.94 1808 0.768 1809 0.634 1810 0.931 1811 0.98 1812 0.766 1813 0.804 1814 0.931 1815 0.931 1816 0.61 1817 0.85 1818 0.93 1819 0.916 1820 0.796 1821 0.88 1822 0.943 1823 0.874 1824 1.051 1825 1.069 1826 0.975 1827 1.408 1828 1.099 1829 0.848 1830 1.093 1831 1.214 1832 1.041 1833 0.996 1834 0.794 1835 1.121 1836 1.217 1837 1.533 1838 1.119 1839 1.249 1840 1.079 1841 0.881 1842 1.454 1843 0.998 1844 1.285 1845 0.962 1846 0.879 1847 1.107 1848 1.17 1849 1.536 1850 1.11 1851 0.971 1852 1.212 1853 1.1 1854 1.137 1855 1.076 1856 0.947 1857 0.802 1858 0.939 1859 0.976 1860 0.771 1861 0.721 1862 0.785 1863 0.871 1864 0.789 1865 0.94 1866 1.023 1867 0.902 1868 0.929 1869 1.148 1870 0.893 1871 0.838 1872 0.998 1873 0.898 1874 0.753 1875 1.121 1876 1.031 1877 0.905 1878 0.89 1879 0.762 1880 1.105 1881 0.824 1882 1.176 1883 1.151 1884 1.2 1885 1.212 1886 1.227 1887 1.072 1888 1.033 1889 1.337 1890 0.964 1891 1.093 1892 1.2 1893 1.039 1894 0.771 1895 0.868 1896 1.005 1897 1.254 1898 1.312 1899 0.874 1900 0.858 1901 0.701 1902 0.761 1903 0.834 1904 1.225 1905 1.051 1906 1.163 1907 1.406 1908 1.338 1909 1.354 1910 1.153 1911 1.0 1912 1.804 1913 1.015 1914 0.852 1915 1.452 1916 1.344 1917 1.073 1918 0.887 1919 1.139 1920 1.038 1921 1.036 1922 1.03 1923 1.089 1924 1.549 1925 0.984 1926 0.992 1927 1.233 1928 1.323 1929 1.051 1930 0.902 1931 0.823 1932 0.859 1933 0.825 1934 0.613 1935 1.145 1936 0.683 1937 0.961 1938 1.097 1939 0.942 1940 0.852 1941 0.796 1942 0.998 1943 0.844 1944 0.807 1945 0.948 1946 0.882 1947 1.012 1948 1.147 1949 1.171 1950 1.109 1951 1.364 1952 0.949 1953 0.914 1954 0.67 1955 0.925 1956 0.858 1957 0.945 1958 0.966 1959 0.732 1960 0.877 1961 0.848 1962 0.956 1963 0.862 1964 0.835 1965 0.726 1966 0.673 1967 0.802 1968 0.75 1969 0.839 1970 0.946 1971 0.831 1972 0.664 1973 1.025 1974 1.036 1975 0.939 1976 0.869 1977 0.696 1978 0.852 1979 0.741 1980 0.673
