# 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.

## 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.
