# 3D-PAWS Build and Deployment Roadmap

Building and deploying a 3D-PAWS station follows a series of stages, beginning with printing the components and ending with long-term operation and maintenance.

The roadmap below outlines the typical workflow used to build, deploy, and operate a station.

***

## Phase 1 — Preparation

### [Print and Prepare Components](https://3dpaws.comet.ucar.edu/building-3d-paws/getting-started/3d-printing-components)

Use a 3D printer to manufacture the structural components of the station.

Typical tasks include:

* Printing instrument components
* Removing supports and finishing parts
* Preparing threads and fittings
* Gathering hardware and tools

Proper preparation of printed parts significantly improves assembly success and long-term durability.

***

### [Assemble Instruments and Sensors](https://3dpaws.comet.ucar.edu/building-3d-paws/building-the-core-instruments)

Build the individual instruments and prepare the data logger hardware.

Typical tasks include:

* Rain gauge assembly
* Wind sensors (anemometer and wind vane)
* Radiation shield and environmental sensors
* Preparing sensor cables and connectors

At the end of this stage, each instrument should be mechanically complete.

***

## Phase 2 — System Integration

### [Integrate and Test Sensors](https://3dpaws.comet.ucar.edu/building-3d-paws/setting-up-the-data-logger)

Connect sensors to the data logger and verify that the system is functioning correctly.

Typical tasks include:

* Wiring sensors to the data logger
* Powering the system
* Confirming sensor readings
* Performing initial calibration checks

Testing at this stage helps identify wiring or configuration issues before field deployment.

***

### [Configure Data Systems](https://3dpaws.comet.ucar.edu/accessing-the-data)

Set up the systems used to collect and visualize station data.

Typical tasks include:

* Configuring the data logger (Particle or Raspberry Pi)
* Creating a CHORDS station configuration
* Setting up webhooks for data ingestion
* Creating Grafana dashboards for visualization

Completing this stage before deployment makes it easier to verify that the station is transmitting data correctly during installation.

***

## Phase 3 — Deployment

### [Select and Evaluate the Station Site](https://3dpaws.comet.ucar.edu/deploying-3d-paws/site-selection)

Choose a suitable location for the station using meteorological siting guidance such as [**WMO No. 8**](https://wmo.int/guide-instruments-and-methods-of-observation-wmo-no-8-0).

Key considerations include:

#### Environmental exposure

* Temperature and humidity sensors should be placed away from artificial heat sources.
* Rain gauges should be positioned away from obstructions that block precipitation.
* Wind sensors should be installed in areas with minimal turbulence.

#### Practical deployment considerations

* Cellular or network signal availability
* Station security
* Safe access for installation and maintenance

Proper siting is critical for accurate meteorological observations.

***

### [Pre-Assemble the Station](https://3dpaws.comet.ucar.edu/building-3d-paws/pre-assemble-the-weather-station)

Before field installation, assemble the full station structure and mount the instruments.

Typical tasks include:

* Mounting sensors on the station frame
* Connecting the sensors to the data logger
* Installing the solar power system
* Verifying cable routing and strain relief
* Verifying the data coming in

This stage acts as a final system verification before deployment.

***

### [Install the Station and Record Metadata](https://3dpaws.comet.ucar.edu/deploying-3d-paws/field-installation-and-deployment)

Deploy the station in the field and verify that the system is operating correctly.

Typical tasks include:

* Installing the station structure
* Verifying power and communications
* Confirming real-time data transmission

#### [Record Station Metadata](https://3dpaws.comet.ucar.edu/deploying-3d-paws/station-metadata)

Document important deployment information, including:

* Station coordinates and elevation
* Sensor heights above ground
* Orientation and mounting configuration
* Power system details
* Installation photos and notes

***

## Phase 4 — Operation and Maintenance

### [Maintain the Station](https://3dpaws.comet.ucar.edu/station-maintenance-and-operations/station-maintenance)

Routine maintenance ensures reliable long-term observations.

Maintenance tasks may include:

* Cleaning sensors and rain gauge funnels
* Inspecting cables and connectors
* Checking data quality and system health
* [Troubleshooting the station](https://3dpaws.comet.ucar.edu/station-maintenance-and-operations/troubleshooting)

Regular maintenance helps ensure consistent environmental observations over time.
