Our reconstruction is based on tree ring d18O series derived from three Pinus merkusii sites from Laos and Thailand. The regional d18O index accounts for 57% of the observed variance of CPRPF. Spatial correlation and 21-year running correlation analyses reveal that CPRPF is greatly influenced by regional precipitation variations associated with the El Nino-Southern Oscillation (ENSO). Periods of enhanced and reduced ENSO activity are associated with strong and weak ENSO-streamflow correlation, respectively. At the longer timescale, the Pacific Decadal Oscillation (PDO) appears to modulate the ENSO-streamflow correlations, with the most extreme flood events along the Chao Phraya River occurring during periods of increased frequency of La Nina events that coincide with extended cold phases of the PDO. The CPRPF reconstruction could aid management planning for Thailand's water resources. #------------------ # Funding_Agency # Funding_Agency_Name: Chinese Academy of Sciences # Grant: XDB26020000, XDA13010106 #------------------ # Funding_Agency # Funding_Agency_Name: National Natural Science Foundation of China # Grant: 41672179, 41671193, 41630529, 41430531, 41690114, 41888101 #------------------ # Funding_Agency # Funding_Agency_Name: National Key R & D Program of China # Grant: 42016YFA0600502, 2017YFE0112800 #------------------ # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: AGS 13-03976, AGS 16-02629 #------------------ # Site_Information # Site_Name: Chao Phraya River CPRPF # Location: Asia>Southeastern Asia>Thailand # Country: Thailand # Northernmost_Latitude: 15.67 # Southernmost_Latitude: 15.67 # Easternmost_Longitude: 100.1 # Westernmost_Longitude: 100.1 # Elevation: #------------------ # Data_Collection # Collection_Name: ChaoPhrayaRiver2019CPRPF # Earliest_Year: 1804 # Most_Recent_Year: 2005 # Time_Unit: CE # Core_Length: # Notes: #------------------ # 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) # ## age_CE age, , ,year Common Era, , , , ,N, ## streamflow streamflow, , , 10^9 cubic meter, August-November,climate reconstructions, , ,N, reconstruction based on tree ring d18O from three Pinus merkusii sites in Laos and Thailand # #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: # age_CE streamflow 1804 10.37 1805 14.84 1806 19.11 1807 14.36 1808 16.23 1809 20.45 1810 18.40 1811 19.27 1812 15.80 1813 19.07 1814 19.97 1815 18.93 1816 12.29 1817 10.40 1818 26.70 1819 27.12 1820 13.78 1821 17.64 1822 25.74 1823 20.16 1824 10.40 1825 10.79 1826 13.78 1827 14.93 1828 18.47 1829 17.64 1830 18.46 1831 18.82 1832 8.83 1833 14.14 1834 18.76 1835 17.52 1836 17.21 1837 13.25 1838 12.19 1839 23.27 1840 18.16 1841 16.57 1842 11.12 1843 10.13 1844 15.58 1845 12.44 1846 17.69 1847 17.53 1848 12.46 1849 14.44 1850 14.20 1851 14.15 1852 12.58 1853 16.46 1854 19.24 1855 10.90 1856 19.03 1857 15.09 1858 10.63 1859 12.53 1860 18.46 1861 19.92 1862 17.68 1863 16.21 1864 8.77 1865 18.11 1866 16.17 1867 15.79 1868 17.58 1869 16.58 1870 17.61 1871 18.22 1872 16.16 1873 12.48 1874 20.00 1875 18.13 1876 17.19 1877 9.37 1878 26.18 1879 25.84 1880 14.65 1881 17.69 1882 21.07 1883 13.96 1884 14.31 1885 10.37 1886 17.82 1887 15.18 1888 11.11 1889 16.68 1890 14.50 1891 9.55 1892 19.75 1893 20.80 1894 18.25 1895 10.14 1896 12.79 1897 19.06 1898 14.50 1899 8.58 1900 17.74 1901 16.86 1902 9.40 1903 23.27 1904 13.36 1905 13.22 1906 11.56 1907 15.32 1908 22.06 1909 21.12 1910 20.97 1911 11.87 1912 11.20 1913 9.21 1914 8.19 1915 15.25 1916 19.74 1917 22.16 1918 10.92 1919 10.17 1920 11.67 1921 14.62 1922 16.10 1923 11.20 1924 12.24 1925 10.42 1926 17.68 1927 14.42 1928 13.29 1929 13.20 1930 11.77 1931 13.26 1932 16.55 1933 17.98 1934 18.61 1935 17.77 1936 7.57 1937 14.21 1938 18.84 1939 12.86 1940 14.35 1941 14.53 1942 18.61 1943 13.39 1944 18.27 1945 13.15 1946 12.54 1947 16.26 1948 13.80 1949 20.60 1950 19.81 1951 18.08 1952 15.00 1953 16.17 1954 18.50 1955 16.77 1956 17.34 1957 14.29 1958 12.89 1959 16.65 1960 14.72 1961 18.63 1962 20.03 1963 15.84 1964 20.97 1965 11.45 1966 13.79 1967 15.47 1968 10.82 1969 10.83 1970 20.76 1971 13.92 1972 12.29 1973 20.94 1974 16.36 1975 24.16 1976 15.03 1977 10.46 1978 19.06 1979 3.38 1980 10.98 1981 15.35 1982 13.55 1983 15.70 1984 11.75 1985 13.11 1986 4.44 1987 12.71 1988 16.32 1989 14.73 1990 11.78 1991 10.72 1992 10.07 1993 9.37 1994 10.98 1995 19.49 1996 17.94 1997 5.38 1998 6.93 1999 16.84 2000 14.14 2001 15.80 2002 10.49 2003 7.64 2004 9.08 2005 12.19
