The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Peru. The time period coverage is from 130 to -54 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

The isotope data correlate with seasonal precipitation and provide a monsoon strength signal for the Amazon and Altiplano for the past 180 years. IITRDB006 ABSTRACT SUPPLIED BY ORIGINATOR: We present results on the relationship between tree ring proxies and regional precipitation for several sites in tropical South America. The responsiveness of oxygen isotopes (d18O) and seasonal growth as precipitation proxies was first validated by high- resolution sampling of a Tachigali myrmecophila from Manaus, Brazil (3.1ºS, 60.0ºW). Monthly growth of Tachigali spp. was significantly correlated with monthly precipitation. Intra-annual measurements of cellulose d18O in Tachigali spp. were also significantly correlated with monthly precipitation at a lag of approximately one month. The annual ring-widths of two tropical tree taxa, Cedrela odorata growing in the Amazon (12.6ºS, 69.2ºW) and Polylepis tarapacana growing in the Altiplano (22.0ºS, 66.0ºW), were validated using bomb-derived radiocarbon 14C. Estimated dates were within two to three years of bomb inferred 14C dates, indicating that these species exhibit annual rings but uncertainties in our chronologies remain. A multi-proxy record spanning 180 years from Cedrela spp. showed a significant negative relationship between cellulose d18O and January precipitation. A 150-year record obtained from Polylepis spp. also showed a significant negative relationship between d18O and March precipitation, whereas annual ring width showed a significant positive correlation with December precipitation. These proxies were combined in a multivariate framework to reconstruct past precipitation, revealing a significant increase in monsoon precipitation at the Amazon site since 1890 and a significant decrease in monsoon precipitation at the Altiplano since 1880. Proxy time series also showed spatial and temporal coherence with precipitation variability due to El Niño forcing, suggesting that oxygen isotopes and ring widths in tropical trees may be important diagnostics for identifying regional differences in the response of the tropical hydrologic cycle to anthropogenic warming.
