hello
I want to use MCD43A4-8days product. How can I access this product in the Google Earth Engine environment?

Hello,
I would just like to verify, are you looking for a product like the MCD43A4 which is produced daily and uses 16 days, only it would be an 8-day instead of 16-day? Or is this a GEE question asking if it is capable of doing that? GEE is not a NASA site, so we are not sure about what all it does. You may need to contact GEE if that is your question.
Thanks,

Yes, my main question is the first part! I saw in the articles that this product has an 8-days , does this product have an 8-days? Or how should I produce eight days from the daily product?

Good Morning,
The temporal frequency of the MCD43 products can be a little confusing. They are a 16-day product that is produced daily. The day given in the individual granule IDs are actually the 9th day of the 16-day period. So, for instance, please see the 2 examples below:

MCD43A4.A2024315.h11v04.061.2024326024347
MCD43A4.A2024316.h11v04.061.2024326030956

The first one is from 2024 day 315 (November 10). The emphasis is on day 315 but the 8 days before 315 and the 7 days after are also used in processing. The second one is from 2024 day 316 (November 11) and it uses the 8 days prior and 7 days following in processing this granule. So, they actually use 15 of the same days to process each granule. These are just some items to consider for your project.
Thanks,
Brett

Hello.
In the area I work (I calculate the vegetation index with MCD43A4) some pixels have no data, how can I mask these pixels?
Best regards

Hello,
I am assuming your software is capable of creating a mask, but I do not know what you have or if I am familiar with your software.
Thanks.
