Abstract

Tree core samples (4 mm in diameter) were extracted from the trunks of white oak (Quercus alba) at three sites in central Iowa (Duvick Back Woods, Ledges State Park, and Pammel). At least 60 trees were sampled at each site, and at least two cores were taken from each tree. The growth rings of each core were dated by calendar year and measured; the measurements were then transformed into dimensionless ring-width indices and correlated with annual precipitation. Data were collected for the years 1680 through 1979. Each tree ring was characterized by the site, year, tree-ring-width index, number of core samples, decade year, and the annual reconstructed precipitation estimate. These data have more than 50% of their variance in common with the known annual statewide average precipitation for Iowa and serve as useful indicators of the precipitation and drought history of the region for the past 300 years. The data are in two files: tree-ring-chronology data (8 kB) and the annual reconstructed precipitation data for central Iowa (2 kB).For access to the data files, click this link to the CDIAC data transition website: http://cdiac.ess-dive.lbl.gov/ndps/ndp002.html

Tree ring chronology indexes and reconstructions of precipitation in Central Iowa, USA

Technical Report Blasing, T J ; Duvick, D N

Over sixty trees were sampled at each of the three Iowa sites; at least two cores were taken from most of the trees. The growth rings of each core were dated by calendar year, following standard procedures. Ring widths were measured to the nearest one-hundredth of a millimeter. Low-frequency variations resulting from tree age, changes in competitive status, and other nonclimatic factors were minimized by fitting a spline curve to the ring-width series and dividing each ring width by the value of the curve for the corresponding span. The average adjusted ring-width index for each year was computed from themore »« less
Volcanic Loading: The Dust Veil Index (1985) (NDP-013)

Dataset Lamb, H. H.

Lamb's Dust Veil Index (DVI) is a numerical index that quantifies the impact of a particular volcanic eruption's release of dust and aerosols over the years following the event, especially the impact on the Earth's energy balance. DVIs have been calculated for eruptions occurring from 1500 through 1983. The methods used to calculate the DVI have been intercalibrated to give a DVI of 1000 for the eruption of Krakatoa in 1883. The DVI for any volcanic eruption is based on a review of the observational, empirical, and theoretical studies of the possible impact on climate of volcanic dust veils. Themore »« less
Monthly Mean Pressure Reconstructions for Europe (1780-1980) and North America (1858-1980) (1987) (NDP-025)

Dataset Jones, P. D. ; Wigley, T. M. L. ; Briffa, K. R.

Real and reconstructed measurements of monthly mean pressure data have been constructed for Europe for 1780 through 1980 and North America for 1858 through 1980. The reconstructions use early pressure, temperature, and precipitation data from a variety of sources including World Weather Records, meteorological and national archives, circulation maps, and daily chart series. Each record contains the year, monthly mean pressure, quality code, and annual mean pressure. These reconstructed gridded monthly pressures provide a reliable historical record of mean sea-level pressures for Europe and North America. The data are in two files: pressure reconstructions for Europe (1.47 MB) and formore »« less
Daily Temperature and Precipitation Data for 223 Former-USSR Stations (NDP-040)

Dataset Razuvaev, V. N. ; Apasova, E. B. ; Martuganov, R. A.

The stations in this dataset are considered by RIHMI to comprise one of the best networks suitable for temperature and precipitation monitoring over the the former-USSR. Factors involved in choosing these 223 stations included length or record, amount of missing data, and achieving reasonably good geographic coverage. There are indeed many more stations with daily data over this part of the world, and hundreds more station records are available through NOAA's Global Historical Climatology Network - Daily (GHCND) database. The 223 stations comprising this database are included in GHCND, but different data processing, updating, and quality assurance methods/checks mean thatmore »« less
The Global Historical Climatology Network: Long-Term Monthly Temperature, Precipitation, Sea Level Pressure, and Station Pressure Data (NDP-041)

Dataset Vose, R. S. ; Schmoyer, R. L. ; Steurer, P. M. ; ...

The GHCN data base contains mean monthly temperature data (in tenths of degrees celsius) for 6039 stations throughout the world. The majority (61%) have records for fewer than 50 years, but a significant proportion (10%) have records in excess of 100 years. It also contains total monthly precipitation data (in tenths of millimeters) for 7533 stations throughout the world. A slight majority (55%) have records in excess of 50 years, and a significant proportion (13%) have records in excess of 100 years. Also in this content is mean monthly sea level pressure data (in tenths of millibars) for 1883 stationsmore »« less
