Cellulose d18O of teak trees from western and central India show a significant positive correlation with the amount of rainfall, which is contrary to expectation. We propose that this correlation is caused by longer duration of the growing season in years of higher rainfall. Teak from southern India shows a significant negative correlation with the amount of rainfall and this relationship is used to reconstruct rainfall back to A.D. 1743, extending the existing regional and local rainfall records by 70 and 128 years, respectively. The reconstructed series reveals higher rainfall for the period 1743-1830 than for the later periods. #------------------ # Funding_Agency # Funding_Agency_Name: Indian Space Research Organization - Geosphere Biosphere Prgram # Grant: #------------------ # Site_Information # Site_Name: Jagdalpur # Location: Asia>Southcentral Asia>India # Country: India # Northernmost_Latitude: 19.065 # Southernmost_Latitude: 19.065 # Easternmost_Longitude: 82.165 # Westernmost_Longitude: 82.165 # Elevation: 560 #------------------ # Data_Collection # Collection_Name: Jagdalpur2011d18O # Earliest_Year: 1865 # Most_Recent_Year: 2004 # Time_Unit: Year CE # Core_Length: # Notes: Jag03 and Jag04 #------------------ # Species # Species_Name: Tectona grandis L. f. # Common_Name: Teak # Tree_Species_Code: TEGR #------------------ # Chronology_Information # Chronology: # #---------------- # Variables # # Data variables follow are preceded by "##" in columns one and two. # Data line variables format: one per line, shortname-tab-variable components (what, material, error, units, seasonality, data type,detail, method, C or N for Character or Numeric data, free text) # ## year_from age at sample start, , , year Common Era, , tree ring , , ,N, some samples are from multiple rings ## year_to age at sample end, , , year Common Era, , tree ring , , ,N, some samples are from multiple rings ## Jag03_d18O delta 18O, cellulose, , per mil, ,tree ring,,isotope ratio mass spectrometry,N, tree ID Jag03 ## Jag04_d18O delta 18O, cellulose, , per mil, ,tree ring,,isotope ratio mass spectrometry,N, tree ID Jag04 # #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: -999 # year_from year_to Jag03_d18O Jag04_d18O 2004 2004 -999 29.2 2003 2003 28.7 29.4 2002 2002 27.8 27.1 2001 2001 27.8 26.9 2000 2000 27.0 28.3 1999 1999 27.0 27.1 1998 1998 28.6 28.7 1997 1997 26.2 27.6 1996 1996 28.3 28.2 1995 1995 27.3 28.5 1994 1994 29.0 29.3 1993 1993 27.8 29.1 1992 1992 28.4 28.4 1991 1991 27.3 28.6 1990 1990 27.9 27.8 1989 1989 26.9 27.2 1988 1988 28.4 28.6 1987 1987 27.8 28.9 1986 1986 28.4 28.3 1985 1985 28.7 28.4 1984 1984 26.0 25.4 1983 1983 28.5 27.8 1982 1982 26.6 26.9 1981 1981 25.4 28.1 1980 1980 27.9 27.4 1979 1979 26.1 25.7 1978 1978 27.5 28.1 1977 1977 28.0 27.9 1976 1976 25.3 25.4 1975 1975 29.0 28.3 1974 1974 26.7 25.8 1973 1973 28.3 27.7 1972 1972 28.5 29.1 1971 1971 27.5 27.7 1970 1970 27.5 27.6 1969 1969 28.9 30.0 1968 1968 28.2 29.0 1967 1967 28.6 30.4 1966 1966 28.3 28.5 1965 1965 25.5 28.9 1964 1964 27.7 28.0 1963 1963 27.7 27.3 1962 1962 26.7 26.7 1961 1961 26.4 28.0 1960 1960 25.2 24.9 1959 1959 25.3 26.1 1958 1958 28.0 25.9 1957 1957 26.7 27.0 1956 1956 27.3 27.4 1955 1955 28.2 28.5 1953 1954 27.9 28.6 1952 1952 27.0 29.5 1951 1951 27.9 26.4 1950 1950 26.8 26.2 1949 1949 26.6 26.4 1948 1948 28.4 28.3 1946 1947 27.5 27.4 1945 1945 24.8 27.6 1937 1944 27.8 27.9 1935 1936 25.0 25.8 1934 1934 27.9 25.7 1931 1933 27.3 25.6 1929 1930 28.1 28.0 1928 1928 27.3 26.5 1927 1927 28.1 29.0 1926 1926 26.6 26.8 1925 1925 27.7 28.4 1924 1924 26.6 29.2 1923 1923 27.6 28.5 1921 1922 29.0 29.0 1920 1920 27.7 28.7 1919 1919 25.1 26.0 1918 1918 25.3 25.8 1916 1917 27.8 27.3 1914 1915 28.1 28.4 1913 1913 27.1 27.5 1912 1912 26.6 26.3 1911 1911 28.0 27.2 1910 1910 27.1 28.1 1908 1909 29.1 28.1 1907 1907 28.3 29.5 1906 1906 28.2 28.9 1905 1905 26.5 26.8 1904 1904 27.2 27.9 1903 1903 27.6 27.7 1902 1902 25.3 25.1 1901 1901 30.8 31.4 1900 1900 26.5 28.3 1899 1899 27.6 28.4 1897 1898 28.7 29.4 1896 1896 26.1 27.3 1895 1895 26.8 26.1 1894 1894 25.6 25.5 1893 1893 26.7 27.4 1891 1892 26.1 26.5 1890 1890 28.0 29.2 1889 1889 27.0 26.9 1888 1888 27.1 27.5 1887 1887 27.8 29.4 1886 1886 25.5 26.8 1885 1885 25.5 27.2 1884 1884 27.1 27.6 1883 1883 27.2 28.0 1881 1882 25.5 24.5 1880 1879 27.1 27.3 1878 1878 28.3 27.4 1876 1877 26.6 27.1 1874 1875 27.3 27.2 1873 1873 26.3 25.9 1872 1872 26.3 28.4 1869 1871 26.5 26.5 1867 1868 27.1 26.9 1865 1866 28.5 27.7
