I have a rather basic question, in relation to the MCD43A4 006 NDVI dataset in GEE. I am aware of the methods used for the generation of the BRDF MODIS dataset, but I would like to know more details about the NDVI product. Does this products in GEE include only high quality observations? How can I check its specifications (e.g. quality, method of generation) in GEE? The only information that I see in GEE is the following :

 The Normalized Difference Vegetation Index is
generated from the Near-IR and Red bands of each scene as (NIR - Red) /
(NIR + Red), and ranges in value from -1.0 to 1.0. This product is generated from the MODIS/006/MCD43A4 surface reflectance composites.
  • I am also interested in this dataset.

It is computed directly from the MCD43A4 imagery and clamped to [-1, 1]. That's it.

  • thanks for your reply. It is unclear though what is its quality. I assume that the best way to find out is to calculate NDVI directly from the MCD43A4 collection and choose the good quality bands. I was really wondering though, if I can find more infos about it. Whoever generated this dataset should provide more information (e.g. how did they use the quality bands?).

    You can do a join to get quality data as described here. Feb 13, 2019 at 20:40
