* Metric Name: Aboveground Carbon Turnover Time *  

* Tier: 1  

* Data Vintage: 09/2020  

* Unit Of Measure: Years  

* Represent element and pillar: Yes  

* Type and distribution of data: Right-skewed distribution representing relative index values. Raw data values range from 0 to 200.  

* Translation: Where is aboveground carbon turnover time high?  

* Translation method and outcome: Raw data values translated to range from +1 to -1 representing more favorable to less favorable conditions, respectively. **** The proposition of more favorable is based on the objective of higher aboveground turnover time (positive linear slope). More favorable (translated to +1) set at 0, less favorable (translated to -1) set at > 60\. Alternative approaches could be to set -1 at the top value, but that would result in a more favorable interpretation of damage potential.

* Metric Definition and Relevance: The average lifetime of aboveground live and dead carbon in years. Locations where the lifetime or turnover time is longer have more carbon in more stable pools, such as large trees or large coarse woody debris. Locations where the lifetime or turnover time is shorter have more carbon in labile pools, such as live or dead leaves.
