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 weather stations that are affordable and flexible for:
* national meteorological services
* research networks
* community monitoring programs
* educational projects
A typical 3D-PAWS station can measure:
* air temperature, pressure, and humidity
* wind speed and direction
* precipitation
* water level and flooding
* air quality
* soil moisture and temperature
Because the system is modular, stations can be customized with additional sensors to match local monitoring needs.
***
### Role in Observation Networks
3D-PAWS is designed to complement, not replace, traditional weather observing systems.
It is especially useful for expanding observation networks in places where conventional stations are difficult or expensive to install.
Used alongside existing networks, 3D-PAWS can help with:
* better coverage across larger areas
* monitoring in remote or underserved regions
* data to support forecasting and modeling
* environmental monitoring for research and 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).
Even though the system is designed to be low-cost and flexible, it emphasizes good site selection, proper sensor exposure, and clear metadata documentation to improve data quality.
Some 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.
