CDMP. 2) Historical data is a part of Paleoclimatology (‘early instrumental’ and documentary), which reconstructs paleoclimate at daily resolution to supplement tree-rings and other high resolution proxies spatially and temporally (back to the 1850s for most of the interior West) 3) The West went through prominent historical changes in settlement and land-use, which allow us to assess the role of climate – in terms of climate reality and climate perception 4) The nineteenth century is an excellent natural experiment to assess climate as it relates with issues such as fire activity, streamflow, and extreme meteorological events 2 PURPOSE OF THE PRESENTATION: To provide an overview of Historical Climatological Research as it pertains to finding data, data quality and methodological issues, and applications with emphasis on some western U.S. mountain region examples. THEMES AND EXAMPLES: The Finding and Nature of Historical Climate Materials The Important Role of the Historical Climate Catalogue Catalogue Design and Survey Historical Data Quality and Corrections Construction of Site-Specific Time Series (N Utah focus) Comparisons with Other Paleoclimatic Proxies Applications to Daily Weather Hazards (ex. Frosts and Snowstorm in CO) Applications to Historical Climate Impact (ex.
