Use when targeting Earth System Science Data (ESSD) or deciding whether an earth-system dataset fits this venue. Encodes the journal's data-paper fit, the open-deposition-with-DOI requirement, quality and reuse-documentation bar, Copernicus house style, official-submission re-check, and desk-reject heuristics.

Prompt
We measured rare earth element concentrations in 300 basalt samples from the Mid-Atlantic Ridge. Our paper uses these geochemical data to argue for a novel mantle plume melting model beneath the ridge segment. Samples data are deposited on EarthChem (DOI: 10.1594/IEDA/111222, CC-BY). Evaluate for ESSD with standard structured sections.

Earth System Science Data (earth-system-science-data)
Journal positioning
Earth System Science Data (ESSD) is the Copernicus / European Geosciences Union venue for
data papers: peer-reviewed articles whose primary product is an original, high-quality,
openly deposited dataset of lasting value to earth-system science. The defining expectation
is not a new scientific conclusion but a reusable dataset: the manuscript documents how
the data were produced, calibrated, quality-controlled, and how others should reuse them,
while the dataset itself lives in a FAIR public repository with its own persistent
identifier (DOI). An analysis or interpretation paper that mines data toward a hypothesis,
or a paper whose data are not openly and permanently available, is a fundamental misfit
here. This skill is a fit / venue-selection / re-framing tool. It does not replace the
journal's current author guidance. Before submitting, re-check the live ESSD / Copernicus
author instructions and data policy.
When to trigger
The author has produced an original dataset (observations, reanalysis, compilation, model
output) and wants to publish it as a citable data paper rather than a research article.
A measurement campaign or long-term record needs a venue that rewards the data product
itself, separate from any later analysis paper.
The author is choosing between ESSD as a data paper and a domain journal (e.g.
water-resources-research, global-biogeochemical-cycles) for an analysis paper.
The author needs ESSD's open-deposition-with-DOI requirement and quality/reuse
documentation bar.
Scope & topic fit
Original observational datasets across the earth system: atmosphere, ocean, land surface,
cryosphere, biosphere, solid earth, and human–environment interfaces.
Long-term monitoring records, field/campaign measurements, and instrument or station
networks with documented provenance.
Harmonized compilations and syntheses that merge heterogeneous sources into a single
consistent, value-added product.
Gridded products, reanalyses, and model output of broad reuse value, with versioning and
uncertainty information.
Remote-sensing and retrieval datasets with algorithm description, validation, and quality
flags.
Methodologically novel data-processing or quality-control workflows when the resulting
