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: Atalani # Location: # Country: Turkey # Northernmost_Latitude: 39.23 # Southernmost_Latitude: 39.23 # Easternmost_Longitude: 28.78 # Westernmost_Longitude: 28.78 # Elevation: 1480 m #-------------------- # Data_Collection # Collection_Name: europe_turk039B # Earliest_Year: 1800 # Most_Recent_Year: 2002 # Time_Unit: y_ad # Core_Length: # Notes: {"sensitivity":"moisture"}{"T1":"4.22191971224"}{"T2":"15.3980612329"}{"M1":"0.0225907866682"}{"M2":"0.480557852979"} #-------------------- # Species # Species_Name: Austrian pine # Species_Code: PINI #-------------------- # 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 1800 0.994 1801 0.855 1802 0.988 1803 1.143 1804 1.087 1805 0.976 1806 0.796 1807 0.898 1808 0.886 1809 0.953 1810 1.375 1811 1.446 1812 1.02 1813 0.758 1814 1.012 1815 0.896 1816 1.011 1817 0.977 1818 1.105 1819 0.855 1820 0.911 1821 1.136 1822 1.061 1823 0.71 1824 0.771 1825 0.926 1826 0.914 1827 1.172 1828 0.866 1829 0.936 1830 0.698 1831 0.91 1832 1.129 1833 1.307 1834 1.043 1835 1.238 1836 1.332 1837 1.131 1838 1.103 1839 1.233 1840 0.787 1841 0.9 1842 0.972 1843 1.007 1844 0.741 1845 0.704 1846 0.985 1847 1.292 1848 1.302 1849 0.94 1850 0.797 1851 0.937 1852 0.615 1853 0.864 1854 0.735 1855 1.064 1856 0.889 1857 0.948 1858 1.113 1859 1.436 1860 1.256 1861 0.799 1862 0.888 1863 0.884 1864 1.075 1865 1.192 1866 1.232 1867 0.892 1868 0.677 1869 0.776 1870 0.733 1871 0.775 1872 1.109 1873 1.116 1874 0.906 1875 0.779 1876 1.228 1877 1.128 1878 0.628 1879 0.678 1880 0.796 1881 1.173 1882 1.106 1883 1.006 1884 0.991 1885 1.291 1886 0.977 1887 0.763 1888 0.975 1889 1.074 1890 0.882 1891 1.131 1892 0.928 1893 0.446 1894 0.501 1895 0.62 1896 0.879 1897 1.119 1898 0.998 1899 0.913 1900 1.098 1901 1.355 1902 1.359 1903 1.279 1904 1.283 1905 1.196 1906 1.178 1907 1.107 1908 0.969 1909 0.706 1910 0.825 1911 0.685 1912 0.893 1913 1.164 1914 1.328 1915 1.283 1916 0.832 1917 1.277 1918 0.943 1919 1.083 1920 1.419 1921 1.307 1922 1.074 1923 1.041 1924 1.028 1925 0.842 1926 0.774 1927 0.831 1928 0.737 1929 0.755 1930 1.01 1931 0.915 1932 0.77 1933 0.756 1934 1.056 1935 0.754 1936 1.087 1937 1.078 1938 0.784 1939 1.114 1940 1.178 1941 1.272 1942 1.069 1943 1.18 1944 0.956 1945 0.738 1946 0.798 1947 0.75 1948 0.843 1949 0.691 1950 0.955 1951 1.062 1952 0.823 1953 0.871 1954 0.811 1955 0.668 1956 0.744 1957 0.714 1958 0.829 1959 1.059 1960 1.256 1961 1.1 1962 0.911 1963 0.902 1964 0.832 1965 0.759 1966 0.908 1967 0.847 1968 0.828 1969 1.024 1970 0.9 1971 0.969 1972 1.129 1973 1.277 1974 0.926 1975 1.177 1976 1.091 1977 0.975 1978 0.791 1979 0.999 1980 0.875 1981 0.877 1982 0.826 1983 0.93 1984 0.994 1985 1.283 1986 1.402 1987 0.984 1988 0.89 1989 0.982 1990 1.054 1991 1.225 1992 1.418 1993 1.245 1994 1.14 1995 0.734 1996 0.99 1997 1.232 1998 1.645 1999 1.34 2000 0.789 2001 1.054 2002 0.923
