tree ring based precipitation reconstruction of northeast iran using juniper tree chronology of lain region
1. introduction long-term climatic data are a prerequisite for hydro-meteorological studies and understanding of past climate. iran is mostly located in semi-arid to arid climate zones, so information on the natural long-term variability of the hydroclimate is of great relevance for land use planning, agriculture, and water supply of a growing population. however, the maximum length of recorded...
متن کاملA 400-year tree-ring chronology from the tropical treeline of North America.
High-elevation sites in the tropics may be particularly sensitive to rapid climate change. By sampling treeline populations, I have developed the first extensive (> 300 years) tree-ring chronology in tropical North America. The site is Nevado de Colima, at the western end of the Mexican Neovolcanic Belt, and the species studied is Mexican mountain pine (Pinus hartwegii). Despite past logging in...
متن کاملIntegrated Tree-Ring-Radiocarbon High-Resolution Timeframe to Resolve Earlier Second Millennium BCE Mesopotamian Chronology
500 years of ancient Near Eastern history from the earlier second millennium BCE, including such pivotal figures as Hammurabi of Babylon, Šamši-Adad I (who conquered Aššur) and Zimrilim of Mari, has long floated in calendar time subject to rival chronological schemes up to 150+ years apart. Texts preserved on clay tablets provide much information, including some astronomical references, but des...
متن کاملClimatic Assessment of a 580-year Chamaecyparis Lawsoniana (port Orford Cedar) Tree-ring Chronology in the Siskiyou Mountains, Usa
Tree-ring data from Chamaecyparis lawsoniana (A. Murr.) Parl. (Port Orford cedar; Cupressaceae) were used to create a standardized chronology, assess the local, limiting factors on radial growth, and investigate the extent of a unique climatic event. We produced a 580-year tree-ring chronology (A.D. 1420 to 2000) from a large number of cedars (n 5 1537) sampled in one 37 km2 area in the Siskiyo...
متن کاملDevelopment of a Tree-Ring Chronology from Eastern Red Cedar (Juniperus virginia, L.) for the Upper Mississippi River Valley
Dendrochronology is the science that uses tree-rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences. There currently is no published record for tree-ring studies using Eastern Red Cedar in the Upper Mississippi River Valley in Wisconsin. Therefore, this study develops a chronology from treerings using Eastern Re...
