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

dataset is the deliverable.

Method & evidence bar

• The dataset must be original and reusable, not a re-packaging of an already-published

product; novelty lies in the data, not in an interpretation.

• The data must be openly deposited in a FAIR repository with a persistent DOI before

acceptance; a "data available on request" statement does not satisfy the journal.

• Production must be fully documented: instruments, sampling, calibration, processing chain,

versioning, and the exact contents and format of the deposited files.

• Quality must be demonstrated with quantitative quality control, validation against

independent references where possible, and explicit, traceable uncertainty.

• Reuse must be enabled: clear metadata, variable definitions, units, flags, file structure,

and guidance on appropriate and inappropriate uses.

• The dataset's value and the user community it serves should be argued concretely, not

asserted.

Structure & house style

• Copernicus data-paper format; the manuscript and the deposited dataset are reviewed

together — re-check current article types and structure on the live guide.

• The text must describe data generation and documentation, not advance a scientific

hypothesis; interpretation belongs in a companion analysis paper elsewhere.

• A prominent data availability statement must give the repository, DOI, version, and

license; the DOI must resolve to the actual data.

• Figures and tables should characterize the dataset (coverage maps, time–space sampling,

validation scatter, uncertainty, flag distributions), not argue a result.

• Open-access, open-review, and open-data are the norm; the deposited files must match what

the paper describes exactly.

Official-submission checklist

• Before giving submission-ready advice, read ../../resources/source-basis.md and

../../resources/official-source-map.md; start from the Copernicus/ESSD anchors, then cite the current ESSD page you checked.

• Search the live site for "Earth System Science Data author guidelines" and follow the

current Copernicus version.

• Confirm the dataset is deposited in an approved FAIR repository with a resolving DOI,

version, and an open license, and that the deposited files match the manuscript.

• Re-check the data-paper structure, abstract/format expectations, and any required dataset

metadata or repository criteria.

• Re-check open-access terms, interactive open-review procedure, competing-interests,

funding, author-contribution, and AI-use disclosure.

• If the live official instructions conflict with this skill, the official instructions

win.

Pre-submission self-check

• ] The deliverable is a reusable dataset, not an analysis/interpretation paper.
• ] The data are deposited in a FAIR repository with a resolving DOI, version, and open license.
• ] Production, calibration, processing, and file contents are fully documented.
• ] Quality is shown with quantitative QC, validation, and traceable uncertainty.
• ] Metadata, variable definitions, units, and flags enable independent reuse.
• ] The deposited files exactly match what the manuscript describes.

Common desk-reject triggers

• An analysis/interpretation paper submitted as if it were a data paper.
• A dataset that is not openly available with a resolving DOI, or is "available on request."
• Re-packaging of an already-published dataset with no original, value-added product.
• Insufficient documentation of production, quality control, or uncertainty.
• Metadata too sparse for independent reuse (missing units, flags, or variable definitions).
• A mismatch between the deposited files and the dataset described in the manuscript.

Re-routing decision

• The dataset underpins a scientific conclusion → an analysis venue such as

communications-earth-and-environment or a domain journal, with ESSD as the data citation.

• Carbon/nutrient flux data feeding a budget analysis → global-biogeochemical-cycles.
• Hydrologic data feeding a process/method study → water-resources-research / journal-of-hydrology.
• Climate model/reanalysis output used for a climate-science argument → journal-of-climate.
• Solid-earth/geochemical data interpreted as a process result → earth-and-planetary-science-letters.
