# 在 Duaer 里查气候预估

在 Duaer 里：某地至 2050 年的高分辨率 CMIP6 气候模式预估：按年或按十年给出平均气温与年降水量。一次成功查询用 1 额度。
## 能拿到什么

Duaer 数据市场里的「气候预估」：某地至 2050 年的高分辨率 CMIP6 气候模式预估：按年或按十年给出平均气温与年降水量。查到结果时用 1 额度，结果交给数字组织的下一个节点。

从节点创建器选 Duaer 数据 → 气候预估，或打开 [数据市场](/zh/getting-started/data-market.md)。相关：[历史天气](/zh/getting-started/weather-history.md)、[太阳辐射与气候（NASA POWER）](/zh/getting-started/nasa-power.md)。

## 适合做什么

- 估算某地到 2050 年的升温与降水变化。
- 比较不同气候模型的结果差异。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → Climate projection。
2. 填 Place（如 Shanghai），或 Latitude + Longitude；From Year、To Year、Step（year 或 decade）、Models 可选。
3. Limit 默认 10，最大 20。执行。

查到结果才扣 1 额度；没有结果、输入有误或上游失败都不扣。

## 用 API 调用

- GET https://api.duaer.com/v1/data/climate-projection?place=Shanghai
- Authorization: Bearer <Duaer key>

下方是与数据市场「复制技能」相同的英文技能，含参数、示例与返回字段。

## 调用技能（英文）

与数据市场「复制技能」一致。

# Duaer Climate projection

Duaer Climate projection aggregates daily output of HighResMIP CMIP6 climate models (through Open-Meteo) for one point, from 1950 to 2050. Compare models to see the spread.

## When to use

- Estimate how warm a city may be in the 2040s.
- Compare rainfall trends between climate models.

## When not to use

- Past observations. Use https://skills.duaer.com/weather-history.md.
- Next week. Use https://skills.duaer.com/weather.md.

## Call

`GET https://api.duaer.com/v1/data/climate-projection?place=Shanghai`

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

## Parameters

Provide `place`, or `latitude` and `longitude`.

- `place` — Place name, such as Seattle. Duaer looks up its coordinates.
- `latitude`, `longitude` — Optional. Coordinates instead of a place name.
- `from`, `to` — Optional. Years from 1950 to 2050. Default 2021 to 2050.
- `step` — Optional. `year` or `decade`. Default `decade`.
- `models` — Optional. Up to 3 of EC_Earth3P_HR, MRI_AGCM3_2_S, CMCC_CM2_VHR4, FGOALS_f3_H, HiRAM_SIT_HR, MPI_ESM1_2_XR, NICAM16_8S. Default EC_Earth3P_HR.
- `limit` — Optional. Rows to return, from 1 to 20. Default 10.

## Examples

- `GET https://api.duaer.com/v1/data/climate-projection?place=Shanghai` — Shanghai by decade to 2050.
- `GET https://api.duaer.com/v1/data/climate-projection?place=Madrid&step=year&from=2040&models=EC_Earth3P_HR,MRI_AGCM3_2_S` — yearly values from two models.

## Result

The response is `{ "items": [...] }`. Each item has `source`, `title`, `url`, and `summary`, plus:

- `place`, `latitude`, `longitude` — the point.
- `period`, `model` — year or decade, and the climate model.
- `meanTemperatureC`, `precipitationMmPerYear`, `years` — averages and years in the period.

These are model projections, not forecasts; single years vary a lot between models.

Fields without a value are left out.

## Credits

A search that returns at least one row uses 1 credit.
An empty search, a search that finds nothing, or a failed search uses 0.
Wrong input returns 400 with a message and uses 0.
No remaining credits returns 402 and does not search.
A missing key returns 401.

## Questions

### Duaer 的气候预估检索扣多少额度？

查到结果时扣 1 额度；没有结果或出错不扣。

### Duaer 气候预估是天气预报吗？

不是。Duaer 气候预估是 CMIP6 模型的长期预估，单一年份在模型间差异很大，适合看十年尺度的趋势。
