This document describes the files used for Century runs discussed in Parton et al. (2004).
The CENTURY model was used to simulate changes in total system carbon resulting from land-use history (1850-2000), and impacts of climate changes and improved land-use managment practices in Senegal.

.100, are not included in this archive as, when the simulations run, these input files are updated for the current site being simulated with site specific weather data and soils data for each of the 1700 grid points.
