U.S. JGOFS Dictionary of parameters

version: Friday, 10 September 2004 (14:53:29 EDT)

We provide this list with the goal of facilitating parameter consistency throughout a JGOFS category. Because there are data we have not considered, or were not sampled during an earlier study, we will be adding to this list from time to time. Please check the version date if you choose to copy the list to your own machine.

If an appropriate parameter name is not found in this list, we have written some guidelines for choosing a parameter name.
