# The Cryosphere (the-cryosphere)

## Journal positioning

The Cryosphere is an open-access European Geosciences Union (EGU) journal, published by Copernicus, and is the disciplinary journal of record for the frozen components of the Earth system — snow, land and sea ice, glaciers and ice sheets, ice shelves, permafrost, and frozen ground. Its defining character is the EGU interactive public peer-review model: a submitted manuscript is posted as a preprint in the discussion forum (EGUsphere), where named referee comments and open community comments appear publicly alongside the authors' responses before a final acceptance decision. The journal rewards complete, rigorous cryospheric studies — observational, remote-sensing, modeling, or theoretical — addressed to the specialist cryosphere community, and values transparency and reproducibility as part of the process, not only the product. This skill is a **fit / venue-selection / re-framing** tool. It does not replace the journal's current official submission guidelines. Before submitting, re-check the live author instructions on the EGU/Copernicus The Cryosphere site.

## When to trigger

- The author names The Cryosphere as the target for a complete study of snow, ice, glaciers, ice sheets, sea ice, or permafrost.
- A manuscript reports cryospheric observations, remote sensing, or modeling with enough depth for full treatment, and the author is choosing between The Cryosphere and Geophysical Research Letters or JGR-Atmospheres.
- An author specifically wants — or needs to prepare for — the EGU interactive public peer-review process with public preprint and open referee discussion.
- The author needs The Cryosphere's open-access terms, data policy, and discussion-stage expectations, plus desk-reject criteria, before submission.

## Scope & topic fit

- Glaciers and ice sheets: mass balance, dynamics, ice-flow modeling, calving, subglacial processes, and ice-sheet contribution to sea level.
- Sea ice: extent, thickness, drift, deformation, sea-ice modeling, and ice-ocean-atmosphere interactions.
- Snow: snowpack physics, snow cover, snow-hydrology, albedo, and snow remote sensing.
- Permafrost and frozen ground: thermal state, active-layer dynamics, ground ice, and permafrost-carbon feedbacks.
- Ice shelves, icebergs, river and lake ice, and other cryospheric features at process or system level.
- Cryospheric methods: new remote-sensing retrievals, field techniques, or model developments delivering a quantitative result, including paleo-cryosphere reconstructions.

## Method & evidence bar

- The study must be complete and rigorous: full methods, validation against independent data or established models, and explicit uncertainty quantification.
- Remote-sensing studies must document the sensor, retrieval, and error budget; field studies must address measurement uncertainty and spatial representativeness.
- Model studies require evaluation against observations and a clear account of sensitivity to key parameters, forcing, and assumptions.
- Because peer review is public, the manuscript must be self-contained and defensible in an open forum: methods transparent, claims calibrated to the evidence, and limitations acknowledged.
- Data and code must be deposited in a FAIR repository (e.g., Zenodo, PANGAEA) with persistent identifiers and cited; Copernicus enforces data and code availability, and assets should be accessible during the open discussion.
- Reanalysis or satellite-product use must justify suitability and document version and processing level.

## Structure & house style

- The Cryosphere uses a standard full-length structure: Abstract, Introduction, Data/Methods, Results, Discussion, Conclusions, with full references and a mandatory data/code-availability section.
- The manuscript is published as a preprint in EGUsphere at the discussion stage; write it to stand as a citable public document and to withstand open referee and community comment.
- Length follows completeness; Copernicus does not impose tight length caps, but every section must be justified and concise.
- Figures must be publication-quality, quantitative, and individually informative; supplementary material carries extended analyses.
- Methods must be reproducible from the main text or supplement, including model versions, forcing datasets, and processing steps.
- Author contributions, competing interests, and the data/code-availability statement are required sections under Copernicus policy.

## Official-submission checklist

- Before giving submission-ready advice, read `../../resources/source-basis.md` and `../../resources/official-source-map.md`; start from the official source anchors for this journal family, then cite the current journal-specific page you checked.
- Search the live site for "The Cryosphere submission author guidelines" and follow the current EGU/Copernicus version.
- Re-check the interactive public peer-review workflow: preprint posting in EGUsphere, the discussion phase, referee and community comment handling, and revision stages.
- Re-check Copernicus data and software availability policy; confirm accepted FAIR repositories and that assets are accessible during open discussion.
- Re-check open-access terms and article-processing charges, plus competing-interests, author-contributions, funding, and AI-use disclosure requirements.
- If the live official instructions conflict with this skill, the official instructions win.

## Pre-submission self-check

- [ ] One sentence — the cryospheric process advanced and the quantitative result that defines the contribution.
- [ ] Methods, model versions, and datasets are fully specified and reproducible from the paper plus supplement.
- [ ] Validation against independent data or models is included, with explicit uncertainty quantification.
- [ ] The manuscript is self-contained and defensible in open, public peer review with named and community comments.
- [ ] Data and code are deposited in a FAIR repository with persistent identifiers and are accessible during discussion.
- [ ] The paper is positioned against recent The Cryosphere literature on this process.

## Common desk-reject triggers

- A short, single-result finding better suited to a rapid letter, lacking the depth a full study requires.
- A modeling study with no evaluation against observations and no sensitivity analysis.
- A descriptive field or remote-sensing report without uncertainty characterization or a generalizable cryospheric result.
- Missing or non-compliant data/code-availability statement, or assets not accessible during the open discussion phase.
- A manuscript not robust enough to withstand public referee and community comment — overclaimed, under-validated, or non-transparent.

## Re-routing decision

- Short, high-impact, broad-interest cryospheric finding needing rapid publication: `geophysical-research-letters`.
- Atmospheric-process emphasis (snow-atmosphere, ice-atmosphere) better suited to a full atmospheric venue: `journal-of-geophysical-research-atmospheres`.
- Broad cross-disciplinary geoscience significance beyond the cryosphere: Nature Geoscience or a high-impact generalist venue.
- Sea-level or Earth-system-futures framing centered on human-Earth trajectories: `earths-future`.
