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: Arbuckle Mountains # Location: # Country: United States # Northernmost_Latitude: 34.45 # Southernmost_Latitude: 34.45 # Easternmost_Longitude: -97.03 # Westernmost_Longitude: -97.03 # Elevation: 900 m #-------------------- # Data_Collection # Collection_Name: northamerica_usa_okB # Earliest_Year: 1767 # Most_Recent_Year: 1973 # Time_Unit: y_ad # Core_Length: # Notes: {"sensitivity":"moisture"}{"T1":"4.17513603535"}{"T2":"17.2693971697"}{"M1":"0.0229044161877"}{"M2":"0.47642718064"} #-------------------- # Species # Species_Name: post oak # Species_Code: QUST #-------------------- # 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 1767 0.74 1768 0.704 1769 0.893 1770 0.655 1771 0.836 1772 0.286 1773 0.605 1774 0.944 1775 0.891 1776 1.079 1777 0.98 1778 0.94 1779 0.636 1780 0.868 1781 1.306 1782 1.156 1783 1.193 1784 0.836 1785 0.721 1786 0.418 1787 0.855 1788 1.099 1789 0.883 1790 0.854 1791 0.754 1792 0.672 1793 1.035 1794 0.824 1795 0.954 1796 1.074 1797 0.799 1798 0.761 1799 1.29 1800 0.808 1801 0.529 1802 1.063 1803 1.595 1804 1.284 1805 0.852 1806 0.82 1807 1.322 1808 0.766 1809 1.421 1810 1.262 1811 1.355 1812 1.009 1813 1.12 1814 0.992 1815 1.369 1816 0.931 1817 1.868 1818 1.369 1819 1.288 1820 1.02 1821 1.087 1822 0.878 1823 1.089 1824 0.722 1825 1.258 1826 1.631 1827 1.346 1828 1.064 1829 0.911 1830 1.07 1831 0.961 1832 0.886 1833 1.374 1834 0.976 1835 1.033 1836 1.702 1837 1.276 1838 1.148 1839 0.958 1840 1.188 1841 0.977 1842 0.761 1843 1.23 1844 1.261 1845 0.977 1846 1.164 1847 1.078 1848 1.027 1849 1.048 1850 0.968 1851 1.011 1852 1.022 1853 1.089 1854 1.262 1855 0.433 1856 0.811 1857 0.841 1858 1.002 1859 0.732 1860 0.85 1861 0.692 1862 0.692 1863 0.62 1864 0.624 1865 0.85 1866 0.916 1867 0.936 1868 0.932 1869 1.096 1870 1.098 1871 1.0 1872 0.9 1873 1.49 1874 0.808 1875 1.031 1876 1.29 1877 1.068 1878 0.911 1879 0.683 1880 0.843 1881 0.894 1882 0.99 1883 0.955 1884 0.928 1885 0.96 1886 0.637 1887 0.578 1888 0.965 1889 0.682 1890 1.018 1891 1.128 1892 1.094 1893 0.854 1894 0.901 1895 0.509 1896 0.859 1897 1.187 1898 1.13 1899 1.086 1900 0.784 1901 0.708 1902 0.875 1903 1.002 1904 0.891 1905 0.957 1906 1.129 1907 1.343 1908 1.423 1909 1.053 1910 0.856 1911 0.62 1912 1.215 1913 0.945 1914 1.016 1915 1.406 1916 1.153 1917 0.848 1918 0.467 1919 1.042 1920 1.217 1921 1.222 1922 0.838 1923 1.009 1924 1.039 1925 0.561 1926 0.843 1927 0.879 1928 1.14 1929 0.994 1930 0.97 1931 0.961 1932 1.049 1933 0.99 1934 0.861 1935 1.012 1936 0.773 1937 0.776 1938 0.819 1939 0.67 1940 0.779 1941 0.88 1942 0.989 1943 0.924 1944 0.96 1945 1.021 1946 1.033 1947 1.06 1948 0.985 1949 0.978 1950 1.132 1951 1.186 1952 0.833 1953 0.723 1954 1.364 1955 1.097 1956 0.778 1957 0.844 1958 1.198 1959 0.841 1960 1.069 1961 1.011 1962 1.235 1963 1.046 1964 0.971 1965 1.236 1966 0.86 1967 1.235 1968 1.419 1969 1.165 1970 1.076 1971 0.985 1972 1.067 1973 1.296
