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,residual,N, ## numsamp number of samples,,,count,,tree ring,,,N, # #-------------------- # Data: # Missing_Values: -999 age_CE trsgi numsamp 1877 577 1 1878 796 1 1879 755 1 1880 919 1 1881 825 1 1882 791 1 1883 1281 1 1884 2721 1 1885 2548 2 1886 1947 2 1887 1296 2 1888 277 2 1889 775 2 1890 872 2 1891 788 2 1892 1184 2 1893 351 2 1894 811 2 1895 531 3 1896 854 3 1897 712 3 1898 1213 3 1899 885 3 1900 781 3 1901 847 3 1902 362 3 1903 892 3 1904 1227 4 1905 895 5 1906 1355 6 1907 1385 6 1908 853 6 1909 1003 7 1910 721 7 1911 1270 7 1912 1014 8 1913 951 8 1914 820 8 1915 1133 8 1916 891 8 1917 720 9 1918 1116 10 1919 965 10 1920 799 10 1921 1136 10 1922 761 11 1923 1039 11 1924 731 11 1925 815 11 1926 1180 11 1927 531 11 1928 1027 11 1929 1229 12 1930 1019 12 1931 789 13 1932 1167 14 1933 1319 14 1934 864 15 1935 1022 15 1936 808 15 1937 665 15 1938 513 15 1939 1155 15 1940 715 15 1941 999 17 1942 964 17 1943 1006 17 1944 683 17 1945 511 17 1946 1113 17 1947 464 17 1948 933 17 1949 1388 18 1950 1131 18 1951 879 18 1952 1044 20 1953 998 21 1954 1014 23 1955 809 23 1956 816 23 1957 932 23 1958 1151 23 1959 1684 23 1960 1174 23 1961 762 23 1962 1015 23 1963 1082 23 1964 1328 23 1965 952 23 1966 894 24 1967 734 25 1968 904 25 1969 703 25 1970 1205 25 1971 891 25 1972 1446 25 1973 1216 25 1974 845 25 1975 913 25 1976 1284 25 1977 1141 25 1978 682 25 1979 855 25 1980 861 25 1981 894 25 1982 736 25 1983 1008 25 1984 869 25 1985 1045 25 1986 638 25 1987 1210 25 1988 632 25 1989 917 25 1990 1089 25 1991 1310 25 1992 1822 25 1993 1326 25 1994 775 24 1995 502 24 1996 1240 24 1997 735 24 1998 996 24 1999 1230 24 2000 889 24 2001 985 24 2002 244 23 2003 1577 21
