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: Manzshir Hiid # Location: # Country: Mongolia # Northernmost_Latitude: 47.77 # Southernmost_Latitude: 47.77 # Easternmost_Longitude: 107.0 # Westernmost_Longitude: 107.0 # Elevation: 1755 m #-------------------- # Data_Collection # Collection_Name: asia_mong002B # Earliest_Year: 1798 # Most_Recent_Year: 1994 # Time_Unit: y_ad # Core_Length: # Notes: {"sensitivity":"moisture"}{"T1":"3.715001774"}{"T2":"16.5009420067"}{"M1":"0.0231070137202"}{"M2":"0.46356401432"} #-------------------- # Species # Species_Name: Siberian stone pine # Species_Code: PISI #-------------------- # 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 1798 1.085 1799 0.867 1800 0.673 1801 0.918 1802 0.464 1803 1.297 1804 1.158 1805 1.132 1806 1.057 1807 1.01 1808 0.759 1809 1.088 1810 1.336 1811 0.842 1812 1.641 1813 1.425 1814 0.934 1815 0.414 1816 1.341 1817 1.189 1818 1.143 1819 0.957 1820 1.09 1821 0.789 1822 0.593 1823 0.919 1824 0.929 1825 0.682 1826 1.004 1827 0.833 1828 1.124 1829 1.354 1830 1.458 1831 1.037 1832 0.441 1833 0.922 1834 0.739 1835 0.481 1836 0.118 1837 1.008 1838 0.833 1839 0.399 1840 0.673 1841 1.395 1842 1.111 1843 1.248 1844 0.391 1845 0.737 1846 1.318 1847 0.994 1848 1.121 1849 1.451 1850 0.95 1851 1.133 1852 0.695 1853 0.925 1854 0.596 1855 0.697 1856 1.255 1857 1.406 1858 0.72 1859 0.734 1860 0.804 1861 0.614 1862 0.711 1863 0.625 1864 1.182 1865 0.806 1866 0.229 1867 0.452 1868 1.006 1869 1.138 1870 1.175 1871 0.361 1872 1.158 1873 1.157 1874 0.55 1875 1.022 1876 0.898 1877 1.321 1878 1.035 1879 1.014 1880 0.616 1881 1.9 1882 0.52 1883 1.031 1884 0.823 1885 0.953 1886 1.858 1887 1.165 1888 0.914 1889 1.119 1890 1.104 1891 0.765 1892 1.406 1893 0.654 1894 0.842 1895 1.61 1896 1.136 1897 1.617 1898 1.102 1899 0.786 1900 1.473 1901 0.624 1902 0.754 1903 0.216 1904 0.589 1905 0.471 1906 0.453 1907 0.984 1908 1.534 1909 1.319 1910 1.263 1911 1.587 1912 2.196 1913 0.832 1914 0.442 1915 1.494 1916 1.725 1917 1.684 1918 1.091 1919 1.633 1920 1.28 1921 1.579 1922 0.703 1923 0.625 1924 0.968 1925 1.069 1926 0.445 1927 1.386 1928 0.478 1929 0.694 1930 0.797 1931 1.235 1932 1.075 1933 1.301 1934 2.126 1935 1.199 1936 1.23 1937 1.346 1938 0.927 1939 1.554 1940 1.128 1941 1.26 1942 0.856 1943 0.613 1944 0.936 1945 0.802 1946 0.8 1947 0.72 1948 0.502 1949 0.952 1950 1.03 1951 0.654 1952 0.563 1953 1.121 1954 0.725 1955 0.992 1956 0.967 1957 0.57 1958 0.893 1959 1.297 1960 1.775 1961 0.546 1962 1.022 1963 0.752 1964 1.497 1965 0.931 1966 0.911 1967 1.612 1968 1.421 1969 0.437 1970 1.164 1971 1.255 1972 0.771 1973 0.736 1974 1.0 1975 1.053 1976 1.31 1977 0.853 1978 1.065 1979 0.739 1980 0.372 1981 0.332 1982 0.756 1983 1.218 1984 0.975 1985 1.383 1986 1.104 1987 0.395 1988 1.413 1989 0.918 1990 0.61 1991 0.952 1992 0.661 1993 1.143 1994 0.833
