MODIS Aqua R2022 granule start time vs R2018
Posted: Tue Aug 16, 2022 5:31 am America/New_York
Hi,
We found that with R2022 the granule start time in the new filenaming convention is not consistent with R2018: with R2018 seconds were always set to 00, but with R2022 there is a mix of 00 and 01, is it normal?
Example:
R2018:

We also found files with seconds different than 00 or 01 and minutes not multiple of 5 with R2022 where they were multiple of 5 and seconds to 00 with R2018, example (files found using the File Search API):AQUA_MODIS.20030101T004501.L2.OC.nc
