Q
How to know the pixels for statistical processing in L3 products?
A
L3 products (statistical:8 days or 1 month) extract high accuracy pixels from products in the target period and perform statistical processing.
Use QA_flag defined in Mask_for_statistics to extract pixels.
For details, Please refer to the following document.
[note] Mask_for_statistics and QA flag may be changed in the future version upgrade.
Please refer to "Q. How to know the product quality of each pixel?" together for the QA flag of L2 products.
