Hi,
I have tried to run carbon seq. model in InVEST following the User Guide. I have uploaded the biomass table in tonne/ha. And run carbon seq. model for 2021 as current and 2041 as future.
But I am not sure about my results.
What units are the results in? ton per pixel or ton per ha? (Because in User Guide I saw: “Note
As of InVEST 3.15.0, the raster results of the Carbon model are given as values per hectare”. And in some of the community posts here I saw reply saying “Results are in ton/pixel”)
I am confuse if my results are logical and the process is correct or not.
And what is the suitable way to show the results?
Please let me know if I need to provide some results, so that I can get some help. Thank you so much for the support.
Thanks for your question and for including your log file. Sorry for the confusion.
Since I can see in your log file that you used InVEST version 3.14.2, your results are in tons/pixel. If you were to upgrade to the newest release, the results would instead be given in tons/ha.
Thank you for your guidance. I got the result as a “average amount of carbon stored in my whole study area” but I want to see carbon stored in each 9 land cover classes that my study area have. Is there any way I can get the value for 9 LULC carbon stored?
“The ideal data source for all carbon stocks is a set of local field estimates, where carbon storage for all relevant stocks has been directly measured.”
It sounds like you’re asking how to calculate the total carbon stored in each land cover class, based on the data you’ve given the model. You can calculate this easily yourself by simply adding up the 4 carbon pool values that you’ve entered in the carbon pool table for each LULC class. You don’t even need GIS to do it. That’s really all the model does to calculate storage on any pixel.
