Global Paleoclimatic Data for 6000 Year B.P., CDIAC NDP-011Entry ID: CDIAC_NDP11
Abstract: The data set consists of pollen, lake level, marine plankton data and, where
possible, quantitative values estimated from these data gathered from 797
stations. The reasons for choosing these three types of data are: (a) they
are quantitative and can be calibrated in climatic terms, and (b) they occur
in networks of samples with good dating controls and broad geographic
coverage. Pollen data ... record the broad scale vegetational patterns that are
related to climate, while the lake level data record the relative water depth
in lakes and therefore provide records of post moisture regimes and changes.
The marine plankton data contain information about the geographic distribution
of plankton, which also reflects climatic patterns.
Regional and global maps of paleoclimatic data show the magnitude and pattern
of climatic variables at a sufficient number of grid points in order to
facilitate comparison with the results of climate model simulations. The
CLIMAP research pioneered quantitative reconstructions of paleoclimate at a
global scale for 18,000 yr B.P. The dataset of paleoclimatic data for 6,000
yr B.P. has been assembled as the initial phase of a long-term project to map
the global patterns of climate for the past 20,000 years and to test the
climate model simulations for dates during this time period.
All CDIAC numerical data packages include copies of pertinent literature
discussing the data, summaries discussing the background, source and scope of
the data, as well as applications limitations and restrictions of the data.
This data set also resides on the CDIAC CD-ROM which contains many other CDIAC
