Missing MYD data March 23 & 31, May 5 & 16

[coleerickson]

Hi,

I'm doing an analysis from 2022-01-01 to present on the h10-11, v7-9 MODIS tiles using the MOD09GA/MOD09GQ/MYD09GA/MYD09GQ products. I've noticed a handful of places where the data is missing from the MYD products.

More specifically, the MYD09GA and MYD09GQ data is missing for days 2022-03-23 (day 82), 2022-03-31 (day 90), 2022-05-05 (day 125), 2022-05-16 (day 136) and locations h10v07, h10v08, h10v09, h11v07, h11v08, v11v09. A subset of this information is available, but most of it is missing.

Can that data be made available? Is there another source for it?

Thank you,
Cole

Hi, I'm checking back in. Should I expect this data to become available or work around its absence?

Thank you,
Cole

Hi Cole,
Unfortunately, the dates you mention all had data anomalies where the data was not collected over thta part of the planet. Please see the MODIS Global browse images for these dates:

Sorry for the inconvenience, Aqua was experiencing issues over that several month period.
Thanks,
