NorthAmerica2k was part of the PAGES 2k Network under Focus 2: Regional Climate Dynamics for the last two millennia.
It was comprised of a group of climate and paleoclimate experts entrusted to carry out the task of producing a high-resolution (at least decadal time scale) reconstruction of the key North American climate system components.
NAmerica2k's objectives included:
1. Identification of the key paleoclimate time series available.
2. Spatiotemporal reconstructions of key climatic parameters: surface air temperature, precipitation, sea surface temperature, air pressure (surface, 500 hPa).
3. Validation of reconstructions through statistical methods; comparison with climate model simulations.
4. Climate model simulations High resolution, global models representing continental climate of the: PMIP simulations at the continental scale and simulations with regional models.
