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: Parambikulam # Location: Asia>Southcentral Asia>India # Country: India # Northernmost_Latitude: 10.38 # Southernmost_Latitude: 10.38 # Easternmost_Longitude: 76.705 # Westernmost_Longitude: 76.705 # Elevation: 400 #------------------ # Data_Collection # Collection_Name: Parambikulam2011d18O # Earliest_Year: 1743 # Most_Recent_Year: 1988 # Time_Unit: Year CE # Core_Length: # Notes: Sample ID PKLM #------------------ # 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 ## d18O delta 18O, cellulose, , per mil, ,tree ring,,isotope ratio mass spectrometry,N, # #---------------- # Data: # Data lines follow (have no #) # Data line format -
