# 在 Duaer 里查海洋数据集（NOAA）

在 Duaer 里：美国海洋和大气管理局 CoastWatch ERDDAP：海表温度、叶绿素、海风等海洋与气候数据集。一次成功查询用 1 额度。
## 能拿到什么

Duaer 数据市场里的「海洋数据集（NOAA）」：美国海洋和大气管理局 CoastWatch ERDDAP：海表温度、叶绿素、海风等海洋与气候数据集。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 → 海洋数据集（NOAA），或打开 [数据市场](/zh/getting-started/data-market.md)。相关：[海浪预报](/zh/getting-started/marine.md)、[美国潮汐预报](/zh/getting-started/tides.md)。

## 适合做什么

- 查找每日海表温度数据集。
- 为海洋研究找到叶绿素数据。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → Ocean datasets (NOAA)。
2. 填 Words（如 chlorophyll）。
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/ocean-datasets?words=chlorophyll
- Authorization: Bearer <Duaer key>
