Pollen: North American Modern Pollen Database

Description

A database of model pollen samples from a network of sites from North America and Greenland, compiled by Whitmore et al. (2005). Associated climatic and vegetation data are also record.

Usage

data(Pollen)
data(Climate)
data(Biome)
data(Location)

source

The database is archived electronically at two sites:

http://www.lpc.uottawa.ca/data/modern/index.html

http://www.geography.wisc.edu/faculty/williams/web/data.htm

Details

These datasets were extracted from Version 1.7 of the North American Modern Pollen Database.

All pollen species were included, however, only the Vegetation type (Biome) field of the AVHRR data and selected Climatic variables were extracted. Requests for additional variables to be included in the versions of the data included in the package should me sent to the package maintainer.
