NOAA Paleoclimatology Reconstructions Network


IPCC Figure 6-10b     NOAA Paleoclimatology's last 2+ millennium Paleoclimate Network contains 92 high-resolution temperature records, annual/seasonal recalibrations to a common anomaly period, and a large accumulation of high-resolution proxy data (1209 time series) that have been used in several recent reconstructions of hemispheric and global temperatures, plus gridded global instrumental data covering 1850-2010, and the NCEP/NCAR Reanalysis. With this proxy and instrumental information, researchers and others interested in later-Holocene climate can now find a complete set of data tools needed to calibrate and make temperature reconstructions, and can compare these with the accumulated high-resolution reconstructions in NOAA Paleoclimatology's archive. Each data type is available in three standard formats (ASCII, Excel, and netCDF) to facilitate working in a variety of computational environments.

PAGES (Past Global Changes) 2K Network

PAGES 2K regional site map    The PAGES 2K Network is made up of nine regional Working Groups. Each regional group collects and processes the best time series and spatial reconstructions of important state variables of the climate system (e.g., surface and 500 hPa geopotential, temperature and precipitation). The reconstructed maps and timeseries will be analyzed in combination with the best ensemble runs of existing Earth System Models (ESMs).

Key Questions

  • What did the main patterns and modes of climate variability on sub-decadal to orbital timescales look and operate like?
  • How does climate variability and extreme events relate to the important primary forcing factors, namely orbital, solar and volcanic?
  • What feedbacks operated to modulate the climate response?

Paleoclimate Reconstruction Challenge


PR Challenge pseudo-proxy Site Map     The last two millennia Paleoclimate Reconstruction (PR) Challenge is designed to engage the scientific PR community in examining its methods in a common framework for the purpose of evaluating their relative strengths and weaknesses. NOAA Paleoclimatology will distribute pseudoproxy data sets that researchers can use to create reconstructions, and NOAA will also distribute the contributed reconstructions so that they can be cross-compared. A key portion of the design of the Challenge is to allow true "apples to apples" comparison of methods across identical experimental platforms. The ultimate goal is to improve last two millennia PR methods so that paleoclimate science can offer the best possible information to help understand both natural and anthropogenic climate change.
