Hi everyone,

My question is about the difference in total carbon -C- stock given in the output report of InVEST (Total cur) and the sum of four C pools.

I have used land use and land cover raster, the table of C pools in CSV format and run the model. It gives the Cabove, C below, Cdead and Csoil results without any problem. However, once I calculate the total amount of carbon in each pool by multiplying the ‘value’ and ‘count’ values of each pool (for this calculation, I used Properties>Symbology>Unique values of each TIF in ArcMap), the result is different than the number given as an output HTML document. Does anyone know what could be the reason of this difference?

Thank you.
