Dear group,

I could not find the sheet that the user guide provided for calculating Kc.  
[https://naturalcapitalproject.stanford.edu/sites/g/files/sbiybj9321/f/kc\_calculator.xlsx](https://naturalcapitalproject.stanford.edu/sites/g/files/sbiybj9321/f/kc_calculator.xlsx)

Could you give it a review and check if the methods and data used on the sheet is still valid?

Hi @urgendalai -

Thanks for pointing out that broken link in the User Guide, I will fix it. Meanwhile, [the InVEST web page](https://naturalcapitalproject.stanford.edu/software/invest/invest-downloads-data) has a link to the Kc calculator that works.
