Question: PACE L1b and Cloud Granule Timestamp mismatch
Replies: 4

Re: PACE L1b and Cloud Granule Timestamp mismatch

If a fuzzy match on filenames doesn't work for you, you could download the L2 file first, and read the "ifile:" from the L2 metadata to ascertain the parent.
e.g.:
:ifile = "PACE_OCI.20250207T001005.L1B.V3.nc" ;
:ofile = "PACE_OCI.20250207T001009.L2.CLD.V3_0.nc" ;

Question: PACE L1b and Cloud Granule Timestamp mismatch

Re: PACE L1b and Cloud Granule Timestamp mismatch

The L1B have the scheduled time of the granule in the name. The L2 names reflect the actual start time of usable data, which may differ from the scheduled time of the granule.

Re: Querying OBPG VIIRS L2 granules through CMR

No, the MODIS and VIIRS SST that we produce are not moving to the Cloud archive - they will continue to be archived locally and those collections will not change.

Re: Querying OBPG VIIRS L2 granules through CMR

The R2022.0 collection is the original CMR collection that points to the OB_DAAC servers at GSFC, and the 2022.0 is the new Earthdata Cloud hosted OB_CLOUD collection that points to AWS. The R2022.0 CMR collections will be deprecated shortly, so you should point your code development at the Cloud ve...

Re: Querying OBPG VIIRS L2 granules through CMR

The L2 granules are each "regional". They combine to give global coverage.

Question: access OCI data

Re: access OCI data

The time period you are referencing should have refined CHL data, not NRT. Remove NRT from your datatype and retry your query.

Re: Changes in VIIRS SNPP L1A data

Yes, when we adopted the new 2020 naming convention, we renamed the existing L1A.
They are the same files.

Question: Question about PACE V3 reprocessing
Replies: 3

Re: Question about PACE V3 reprocessing

Your query is looking for Near Real Time (NRT) granules in a time range when there are only Refined granules available. The refined period is 05-mar-2024 through 31-Jan-2025. If you remove the "_NRT" from the collection name, you will be querying the correct collection.
