The latest generation of state-of-the-art climate models project future widespread drying in the subtropics. Here, we reconstruct spatially-complete gridded Palmer drought severity index values back to A.D. 1179 over Morocco, Algeria, and Tunisia. The reconstructions provide long-term context for northwest African hydroclimatology, revealing large-scale regional droughts prior to the sixteenth century, as well as more heterogeneous patterns in sixteenth, eighteenth, and twentieth century. Over the most recent decades a shift toward dry conditions over the region is observed, which is consistent with general circulation model projections of greenhouse gas forced enhanced regional subtropical drought. #------------------- # Site_Information # Site_Name: Jebnoun # Location: Tunisia # Northernmost_Latitude: 35.85 # Southernmost_Latitude: 35.85 # Easternmost_Longitude: 9.3 # Westernmost_Longitude: 9.3 # Elevation: 800 #------------------- # Data_Collection # Collection_Name: TUNI003 # Earliest_Year: 1874 # Most_Recent_Year: 2003 # Time_Unit: AD # Notes: #------------------- # Species # Species_Name: Pinus halepensis Mill. # Common_Name: Aleppo pine # Tree_Species_Code: PIHA #------------------- # Chronology_Information # Chronology: #--------------------- # Variables # variables format: shortname var components: what,material,error,units,season,archive,detail,method, C or N for Char or Numeric data,additional information ## age_CE age,,,year Common Era,,tree ring,,,N, ## trsgi tree ring standardized growth index,,,,,tree ring,composited,standard,N, ## numsamp number of samples,,,count,,tree ring,,,N, # #-------------------- # Data: # Missing_Values: -999 age_CE trsgi numsamp 1874 851 1 1875 381 1 1876 68 1 1877 261 1 1878 541 1 1879 559 1 1880 719 1 1881 711 1 1882 660 1 1883 1145 1 1884 2030 2 1885 2758 2 1886 2239 2 1887 1575 2 1888 460 2 1889 622 2 1890 877 2 1891 772 2 1892 1115 2 1893 384 2 1894 664 3 1895 473 3 1896 643 3 1897 588 3 1898 1061 3 1899 899 3 1900 711 3 1901 730 4 1902 572 5 1903 565 5 1904 1362 5 1905 956 6 1906 1052 6 1907 1378 6 1908 933 7 1909 921 7 1910 804 7 1911 1240 8 1912 1119 8 1913 1018 8 1914 1002 8 1915 1294 9 1916 1011 10 1917 647 10 1918 1010 10 1919 978 10 1920 837 11 1921 1123 11 1922 780 11 1923 903 11 1924 691 11 1925 747 11 1926 1188 11 1927 628 11 1928 894 12 1929 1292 13 1930 1141 14 1931 725 14 1932 1184 14 1933 1518 15 1934 949 15 1935 946 15 1936 885 15 1937 663 15 1938 438 15 1939 1101 16 1940 810 17 1941 856 17 1942 1026 17 1943 1035 17 1944 656 17 1945 395 17 1946 1036 17 1947 564 17 1948 722 18 1949 1403 18 1950 1247 18 1951 808 20 1952 976 22 1953 1073 23 1954 1044 23 1955 806 23 1956 774 23 1957 916 23 1958 1153 23 1959 1711 23 1960 1259 23 1961 678 23 1962 939 23 1963 1185 23 1964 1356 23 1965 981 24 1966 809 25 1967 711 25 1968 854 25 1969 699 25 1970 1155 25 1971 982 25 1972 1389 25 1973 1331 25 1974 844 25 1975 838 25 1976 1335 25 1977 1232 25 1978 683 25 1979 775 25 1980 907 25 1981 903 25 1982 744 25 1983 958 25 1984 886 25 1985 995 25 1986 643 25 1987 1100 25 1988 679 25 1989 766 25 1990 1098 25 1991 1325 25 1992 1856 25 1993 1424 25 1994 721 24 1995 432 24 1996 1189 24 1997 838 24 1998 909 24 1999 1275 24 2000 956 24 2001 927 24 2002 252 23 2003 1416 21
