# Station Data

Query weather station observation data including temperature, wind, precipitation, and more.

## Query station observation data

> Query weather station observation data including:\
> \- Temperature, dew point, wind speed/direction\
> \- Atmospheric pressure (surface and MSL)\
> \- Precipitation accumulations (1h, 3h, 6h, 12h, 24h)\
> \- Solar radiation and cloud cover\
> \
> \*\*Filtering Options:\*\*\
> \- \`station\_ids\`: List of specific station IDs\
> \- \`bounding\_box\`: Geographic bounds (min/max lat/lon)\
> \- \`variables\`: Subset of observation variables\
> \
> \*\*Temporal Aggregation:\*\*\
> \- \`none\`: Raw observations (default)\
> \- \`hourly\`: Hourly averages\
> \- \`daily\`: Daily averages\
> \
> \*\*Response Formats:\*\*\
> \- \`json\`: Columnar JSON format \`{column: \[values], ...}\`\
> \- \`arrow\`: Apache Arrow IPC stream for efficient processing\
> \
> \*\*Authentication\*\*: Requires API key.\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jua.ai/api-v2/query-engine/open-api-reference/station-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
