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. #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: ESH0317288 #-------------------- # Site_Information # Site_Name: Pinus Nigra Reserve # Location: Algeria # Northernmost_Latitude: 36.45 # Southernmost_Latitude: 36.45 # Easternmost_Longitude: 4.1 # Westernmost_Longitude: 4.1 # Elevation_m: 1560 #-------------------- # Data_Collection # Collection_Name: ALGE002 # First_Year: 1569 # Last_Year: 2005 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: ring width # Notes: #-------------------- # Species # Species_Name: Pinus nigra J.F.
