When I googled my question, I found a document saying the L1As at OB are a "reduced" version of standard L1As: http://oceancolor.gsfc.nasa.gov (.reprocessing/r2009/band_subsettted_level1a/)
But since this document was for r2009, I was wondering whether at present theMODIS L1A granules for both Terra and Aqua at OB are still reduced?
Thanks in advance for your time.
you'd see this page linked: https://oceancolor.gsfc.nasa.gov/reprocessing/r2009/format/#level1
But so you don't have to follow the link, it says that (as of the R2009 reprocessing), the L1A file format is identical to that distributed by LAADS ...and that is still true.
I found the production time listed in the local granule ID name inside the L1A granule on OB is different from the normal granule on LAADs which has the same collecting timestamp, nor different from the NRT granule on LANCE that is also with the same timestamp. Does this difference count for something when using the L1A granules on OB?
