name: ngeo-cover-letter
description: Use when writing the cover letter for a Nature Geoscience submission, which must convince an in-house editor that the work is a broad-interest Earth-system advance appropriate for a diverse readership. Drafts the editorial case; does not edit the manuscript itself.

# Nature Geoscience Cover Letter (ngeo-cover-letter)

## When to trigger

- You are about to submit and need the cover letter
- The in-house editor will triage on broad interest and Earth-system importance before sending it for review
- A prior submission was declined without review on interest grounds and you are reframing
- You need to note suggested / excluded referees (coordinate with `ngeo-referee-strategy`)

## Why the cover letter matters at Nature Geoscience

Nature Geoscience is handled by **professional in-house editors** (no external editorial board), who **desk-reject the majority of submissions before review**. The cover letter is the editor-facing argument that the manuscript is a **broad-interest Earth-system advance** worth sending to referees. Two journal-specific facts shape it:

- **There is no presubmission enquiry route.** Nature Geoscience does not accept presubs, so the cover letter carries the full "why this, why here, why now" case that other journals let you test informally first.
- **The cover letter is not seen by peer reviewers.** It is written *for the editor*: candid about significance and fit, without the hedging you would use for a skeptical referee.

It is not an abstract, not a summary, and not a place to oversell. It is a concise, specific, editor-facing case for general interest.

## Structure (concise, ~3–5 short paragraphs)

1. **Submission line** — title, that it is submitted to Nature Geoscience as an Article (or Brief Communication), and the broad topic area.
2. **The headline advance** — one or two sentences stating the single result plainly, with the key quantitative finding and its significance.
3. **Why it is an Earth-system advance** — what is new: a newly identified process, a decisive constraint, a resolved controversy, a dataset revealing a hidden signal. Tie it to a prior belief it changes.
4. **Why it is of broad, cross-disciplinary interest** — name the Earth-science communities beyond your subfield who will care and *why*. This is the paragraph editors weigh most.
5. **Housekeeping** — originality / not under consideration elsewhere; relation to any prior preprint (e.g. ESSOAr/EarthArXiv) or conference version; data/code availability status; suggested and excluded referees (per `ngeo-referee-strategy`); whether you opt into double-blind review; any related manuscripts under consideration.

## The broad-interest paragraph (the load-bearing one)

- Be **specific**: "This bears on [neighboring field] because [concrete process/transfer]," not "this is of broad interest to the geoscience community."
- Anchor importance to a **change in understanding of the Earth system**, not to a new regional record alone.
- If borderline, pre-empt the "this is a regional study, why not JGR?" reaction by stating explicitly what makes it cross-cutting and first-order.
- Emphasise **quantitative evidence and grounding** — that the advance rests on data (or a data-validated model) with quantified uncertainty.
- Keep it honest — editors discount inflated breadth or impact claims, and overreach can backfire.

## Checklist

- [ ] States submission to Nature Geoscience, the content type, and the topic area
- [ ] Headline advance stated in one or two sentences with the key number
- [ ] Importance tied to a concrete Earth-system change in understanding (not just a new record)
- [ ] Broad-interest paragraph names specific out-of-subfield audiences and why
- [ ] Pre-empts the "regional / community-journal" reaction if borderline
- [ ] Notes quantitative grounding and quantified uncertainty
- [ ] Originality / concurrent-submission statement included
- [ ] Prior preprint / conference version disclosed if applicable
- [ ] Suggested / excluded referees noted (coordinate with ngeo-referee-strategy)
- [ ] Double-blind opt-in indicated if chosen
- [ ] Tone is specific and measured, not promotional

## Anti-patterns

- A cover letter that just restates the abstract
- Asserting "broad interest to the geoscience community" with no concrete audience
- Overselling significance or impact the manuscript does not support
- Omitting the broad-interest argument (the single most common miss at a triage-heavy journal)
- Hiding a prior preprint the editor will find anyway
- Forgetting there is no presub safety net — the letter must carry the full case

## Output format

```
【Submission line】Article/Brief Comm. to Nature Geoscience, topic: ...
【Headline advance】one sentence + key number
【Importance】new process / decisive constraint / resolved controversy + belief changed
【Broad interest】named out-of-subfield audiences + concrete reason (the key paragraph)
【Grounding】data/model + quantified uncertainty noted?  yes / fix
【Housekeeping】originality / preprint / referees / double-blind opt-in
【Tone】specific & measured?  yes / fix
【Next】ngeo-referee-strategy then ngeo-submission
