Carbon Model: How to compute values of above carbon pool for each LULC class?
I have been struggling with a basic principle of the carbon model, where one of the inputs is a table (.e.g csv) of each carbon pool associated with each LULC class. Specifically, say that I have a raster map of NPP (net primary productivity) and I want to use it to fill out above-ground values for each of my LULC classes. My question is: should I run a zonal statistics type of analysis and take an AVERAGE of NPP falling inside each of my LULC "zones", or should I take a SUM of NPP over each class? I guess I need to better understand whether the above carbon value should represent a cumulative measure for each class or an average. Any help is much appreciated!
