NASA MERRA-2
Before you use this
- Documentation status records an absence, not a finding. The seed inventory has no field for documentation, so this record says none because nothing was captured — not because the dataset is undocumented. Many of these are extensively documented upstream.

The exclusions are the half you cannot get anywhere else. A dataset that is wrong for your question is worth knowing about before you build on it.

No field-level metadata yet.
Field-level metadata has not been captured for this record yet. It is at completeness level 1; field descriptions arrive at level 2.
Three independent facets
Graded separately and never combined. A dataset can be perfectly current and completely unprovenanced, and one number would hide exactly that.
Provenance
–Not yet assessed
Not the same as a poor grade. Provenance and documentation are graded from field-level metadata, which this record does not carry yet.
Documentation
–Not yet assessed
Not the same as a poor grade. Provenance and documentation are graded from field-level metadata, which this record does not carry yet.
Currency & maintenance
–Not yet assessed
No update cadence is recorded, so there is nothing to be past due against. Absent means not captured, not that the dataset has no cadence.
Not the same as a poor grade. Provenance and documentation are graded from field-level metadata, which this record does not carry yet.
This record is at completeness level 1. Provenance and Documentation are assessed from field-level metadata, which a level 1 record does not carry. Not yet assessed is not the same as poor.
Visible without signing in, deliberately: an evaluator comparing catalogs should not have to register first.

OpenGrid redirects you to the source and never proxies the bytes. For a partial read of a large dataset, use the SDK — it fetches an access plan and reads only the slice you asked for.
