Carbon Storage and Sequestration Model: Issues with estimation of carbon sequestration

[pravinyab]

I tried running CSS model for estimating the monetary valuation of carbon sequestration in Goa. The model ran successfully and I have the result. But the issue is with the carbon sequestration.

CSeq (InVEST estimated) is not equal to [ Alternate Carbon Storage - Baseline Carbon Storage]

Attaching a photo of the result and the log file for reference. The same mistake I got for all other states over the years.

PS: I checked the properties of both the maps used, and they are identical.

Please revert ASAP.

What is your question? The log file indicates that it finished successfully:

Do your results look ok?

Hello,

I have issues with the value of Carbon Sequestration (Change in Carbon Storage)… Baseline Carbon Storage is 15761589.84 and alternate carbon storage is 15683651.29. InVEST estimated Change in carbon storage equal to 923.78. Should not the carbon sequestration be around 77000 (Alternate carbon storage- baseline carbon storage)?

For reference,
