# 3D-Printed Automatic Weather Station (3D-PAWS)
3D-PAWS station showing a typical configuration with core meteorological instruments and modular components.
***
#### Overview
3D-PAWS is an open, modular weather and environmental monitoring system that helps make reliable observations more accessible.
It combines 3D-printed parts, open-source electronics, and cloud-based data tools to create affordable and flexible observing systems. A typical station measures temperature, pressure, humidity, wind, and precipitation, with additional sensors available for applications such as water level, air quality, and soil monitoring.
Because the system is modular, stations can be configured to match local monitoring needs.
***
#### Role in Observation Networks
3D-PAWS is designed to complement, not replace, traditional weather observing systems.
It can expand observation networks in locations where conventional stations are difficult or expensive to install, providing additional observations for forecasting, modeling, research, and environmental decision-making.
***
#### Observing Practices and Standards
3D-PAWS follows widely accepted meteorological practices, including guidance from the *World Meteorological Organization* [***(WMO) Guide to Instruments and Methods of Observation (WMO-No. 8)***](https://community.wmo.int/site/knowledge-hub/programmes-and-initiatives/instruments-and-methods-of-observation-programme-imop/guide-instruments-and-methods-of-observation-wmo-no-8), particularly [**Volume I – Measurement of Meteorological Variables**](https://library.wmo.int/records/item/68695-guide-to-instruments-and-methods-of-observation?offset=3).
Good site selection, proper sensor exposure, and clear metadata documentation are emphasized throughout this manual to improve data quality.
Some 3D-PAWS measurements differ from traditional reference standards. For example, wind sensors are usually installed about **2 m above ground level**, rather than the 10 m height used in many operational networks.

## 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://3dpaws.comet.ucar.edu/3d-printed-automatic-weather-station-3d-paws.md?ask=&goal=
```
`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.
