## 能拿到什么

Duaer 数据市场里的「太阳辐射与气候（NASA POWER）」：NASA POWER 提供的任意地点自 1981 年起的逐日或逐月太阳辐射、气温、降水、风速与湿度。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 → 太阳辐射与气候（NASA POWER），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)、[海拔高程](/zh/getting-started/elevation.md)。

## 适合做什么

- 估算场址的太阳能资源（kWh/m²/天）。
- 按月比较某地多年的气温与降水。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → Solar and climate (NASA POWER)。
2. 填 Place（或 Latitude + Longitude）、From、To；Step 可选 day 或 month，默认 day。
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。

# Duaer Solar and climate (NASA POWER)

Duaer Solar and climate (NASA POWER) reads satellite and model estimates for any point on Earth since 1981. It suits solar sizing, agriculture, and climate checks where no weather station exists.

## When to use

- Estimate solar energy for a site, in kWh per square metre per day.
- Compare monthly temperature and rain for a location over years.

## When not to use

- A forecast for the coming days. Use https://skills.duaer.com/weather.md.
- Hourly station-like history. Use https://skills.duaer.com/weather-history.md.

## Call

## Parameters

Provide `place` (or `latitude` and `longitude`), `from`, and `to`.

- `place` — Place name, such as Lhasa. Duaer looks up its coordinates.
- `latitude`, `longitude` — Optional. Coordinates instead of a place name.
- `from` — First day, YYYY-MM-DD. Data starts in 1981.
- `to` — Last day, YYYY-MM-DD. Recent days appear after about a week.
- `step` — Optional. `day` or `month`. Default `day`. Daily ranges stay within one year; monthly ranges within ten years.
- `limit` — Optional. Rows to return, from 1 to 20. Default 10.

## Examples

- `GET https://api.duaer.com/v1/data/nasa-power?place=Dubai&from=2024-06-01&to=2024-06-07` — one week of daily sunlight and heat in Dubai.
- `GET https://api.duaer.com/v1/data/nasa-power?place=Kunming&from=2023-01-01&to=2023-12-31&step=month&limit=12` — monthly climate for a year.

## Result

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

- `place`, `latitude`, `longitude` — the point used.
- `period`, `step` — day (YYYY-MM-DD) or month (YYYY-MM), oldest first.
- `solarKwhM2Day` — all-sky solar radiation on a flat surface.
- `temperatureMean`, `temperatureMax`, `temperatureMin` — °C at 2 m.
- `precipitationMmDay`, `windSpeedMs`, `humidityPct` — rain, wind at 10 m, relative humidity.

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.
