Missing S2 L2A data #381

Open sfalkena opened 1 month ago

sfalkena commented 1 month ago

Hi,

I have found that Sentinel 2 data for the date of 16-03-2019 in the south France area are missing from Planetary Computer.

In specific, EO browser shows s3://sentinel-s2-l2a/tiles/31/T/FJ/2019/3/16/0/ to be available, where this result is not returned to me through either the PC API or explorer. Note that it is not just this tile, but this complete aqcuisition strip.

Is there a possibility to backfill this? Thanks in advance!

Sieger

Really appreciate you bringing this to our attention, it does appear to be missing, both from the STAC metadata side as well as raw data within blob storage. We don't seem to be missing the entire day though, e.g. we've got T30UVU on the 16th, just a random spot also in France (id S2A_MSIL2A_20190316T112111_R037_T30UVU_20201007T071721). There is also a bunch of data on the 17th nearby. Before potentially backfilling let me check if any other tiles are missing from our data storage, and I'll report back.

Looks like there are several missing tiles, but they do appear to be in our upstream data provider's database, so we will be looking into doing a backfill, will probably be a week or two before it happens, will report back here once it's done.

@sfalkena just an FYI, we have started to backfill data, eg here's the specific tile you first mentioned-

Thanks a lot! Can you close the issue once backfilling is done?
