Thresholding methods of NDVI

Hello,
In the NIVA project, we are working on the development of agro-environmental indicators and in particular carbon storage using the Sen4CAP chain.
Processors allow us to identify the harvest date of the main crop as well as the start date of the intermediate crop. However, for the calculation of carbon storage indicator we need to know the starting and ending dates of the main crop and of the cover crop.
Is it possible to know the thresholding methods of NDVI in order to extend its application in the calculation of the NIVA indicators?

Many thanks.
Guillaume.

Dear Guillaume,

this is explained in the “ATBD for L4C agricultural monitoring product 1.2” document, accessible here: http://esa-sen4cap.org/content/technical-documents

Best regards,
