Historical climate model output of ECHAM5-wiso from 1871-2011 at T106 resolution
<p>Historical climate model simulation of the isotope-enabled ECHAM5-wiso model from the years 1871 to 2011 at T106 (1 degree) resolution. The model code was provided by Martin Werner of AWI. The simulations were designed and run by Nathan Steiger on the Yellowstone supercomputer. The boundary conditions were interpolated HadISST fields. The simulations also included updated fractionation factors (an option within the ECHAM5-wiso Fortran code). All variables here are at monthly resolution in netcdf format. Please contact Nathan Steiger if you have any questions about the simulation. In addition to the data citation, please also cite the following reference for where the data were first published: Steiger, N.J., E.J. Steig, S.G. Dee, G.H. Roe, and G.J. Hakim, (2017): <em>Climate reconstruction using data assimilation of water-isotope ratios from ice cores.</em> Journal of Geophysical Research: Atmospheres, doi:10.1002/2016JD026011.</p>Standard variables include: ECHAM5 T106 orography, 2 m temperature, surface pressure, mean sea level pressure, vertically integrated water vapor, total precipitation, evaporation, soil moisture, relative humidity, specific humidity, atmospheric stream function at 200 hPa, geopotential height at 500 hPa, windspeed at 10 m, and u-velocity wind at 200 hPa.
Isotope variables include: d18O and dD of total precipitation, d18O and dD of evaporation, d18O and dD of snow fall, d18O and dD of seasonal snow cover, d18O and dD of snow on glaciers, d18O and dD of soil moisture, and specific humidity of water isotopes

Paleo Hydrodynamics Data Assimilation product (PHYDA)
See the associated publication: Steiger, N. J., Smerdon, J. E., Cook, E. R., and Cook, B. I., A reconstruction of global hydroclimate and dynamical variables over the Common Era, Scientific Data, 5:180086, doi: 10.1038/sdata.2018.86.
This database provides the first truly global reconstructions of hydroclimate along with associated climate dynamical variables over the past two thousand years. The reconstructions were made with an improved data assimilation reconstruction approach that optimally combines 2,978 paleoclimate proxy-data time series with the physical constraints of an atmosphere--ocean climate model. Three separate global reconstructions were created from the years 1 to 2000 CE, targeting annual means (defined as April to the next calendar year March), the boreal growing season of June, July, and August (JJA), and the austral growing season of December, January, and February (DJF); each of these reconstructions is contained in a separate NetCDF file. The reconstructions include three global variables gridded at about 2 degree resolution: surface temperature at 2 m, the Palmer drought severity index (PDSI), and the standardized precipitation evapotranspiration index (SPEI). Dynamical variables also included for each reconstruction: the global mean temperature, the North Atlantic sea surface temperature index which is the non-detrended and non-smoothed version of the Atlantic multidecadal oscillation (AMO), the monthly Nino SST indices (Nino 1+2, 3, 3.4, 4), the monthly equatorial Pacific zonal SST gradient, and the location of the intertropical convergence zone (ITCZ) in 11 longitudinal zones.
A 100 member ensemble (randomly drawn from the original reconstruction ensemble) is available externally due to Zenodo file size restrictions: http://clifford.ldeo.columbia.edu/nsteiger/recon_output/phyda_ens/

Nathan Newsom diary
Narrative account entitled "A Short summary of a journey, taken by volunteers from Gallia County; for the purpose of destroying Indians and the invasion of Canada," written by Nathan Newsom. Newsom was an orderly sergeant in Captain Calvin Shepard's company from Gallia County, Ohio, during the War of 1812. This volume conveys conditions experienced by soldiers during the war, including low pay, shortages of food and clothing, low morale, and severe weather conditions. Newsom also describes the cooperation of the army with friendly Indians and the disciplinary measures taken for desertion and other offenses
