## 能拿到什么

Duaer 数据市场里的「全球地磁 Kp 指数」：NOAA 每三小时一次的全球 Kp 指数：近期观测的地磁活动或未来三天预报，并标注地磁暴等级。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 → 全球地磁 Kp 指数，或打开 [数据市场](/zh/getting-started/data-market.md)。相关：[空间天气预警](/zh/getting-started/space-weather.md)、[小行星近地掠过](/zh/getting-started/close-approaches.md)。

## 适合做什么

- 判断今晚是否可能看到极光。
- 查看近几天的地磁暴等级。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → Planetary Kp index。
2. 填 View（recent 或 forecast）。
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
