MOD13Q1 HDF missing files

by julio.esquerdo » Mon Dec 19, 2022 12:46 pm America/New_York

Hello there!

I realized there are several HDF missing files for MOD13Q1 products (6.1 version) in 2001 year, such as 2001.01.01 and 2001.03.06 folders.

https://e4ftl01.cr.usgs.gov/MOLT/MOD13Q1.061/2001.01.01/
https://e4ftl01.cr.usgs.gov/MOLT/MOD13Q1.061/2001.03.06/

Could you please check it?

Thanks in advance.

Julio Esquerdo

Hi @julio.esquerdo The MODIS team is currently working on historically processing the MODIS Version 6.1 data. These data will be available in the future. The LP DAAC will post a news announcement on our website and on the Earthdata Forum once the historical processing effort has been completed. Thank you.

Hi all,

Now, on the website said that "MODIS Version 6 Forward Processing has been Discontinued". So, I started to update all my MODIS data to collection 6.1, but I realize that still there are some dates missing. The following dates are not found on the https://e4ftl01.cr.usgs.gov/ for MOD13Q1.061

"2001.01.17"
"2001.02.18"
"2001.04.07"
"2001.05.09"
"2001.06.10"
"2001.12.19"
"2002.01.01"
"2002.02.02"
"2002.03.06"

Any notice about that, are there some problems with that specific dates?

Hello @frzambra we are currently working on historically processing the data. We expect these files to be available once that effort is completed. We will post a news announcement (https://lpdaac.usgs.gov/news/) and send out a listserv message once the effort has been completed.

Hello,

As the 2001 images of MOD13Q1 V.061 are not available yet, is it possible to use V.006 of these dates instead to fill the missing period? Should I expect some problem using V061 and v006 together?

Thanks.

Hi Julio,
Ideally,it is best to use the same version, however for now there really is no other choice. When there is coverage from both Versions for you area of interest you may want to make a comparison just to check if there is much difference. The algorithm changes made between the versions were not really supposed to affect upper level land data much at all. Sorry for the delay, we are still trying to get the data, but the data providers have not been very cooperative.
Thanks,
Brett
