# Asset Management

Operating a network of 3D-PAWS stations requires more than installing hardware in the field. Long-term reliability and data quality depend on keeping organized records of station deployments, maintenance activities, sensor replacements, and system components.

An **asset management system** helps track this information and supports efficient operation of a monitoring network.

Asset management systems do not need to be complex. Many networks successfully manage stations using spreadsheets, shared folders, or simple databases. The most important factors are **consistent record keeping and linking information to each station**.

***

## Key Elements of an Asset Management System

A practical asset management system should track the following information.

### Station Registry

The station registry is the master list of all stations in the network.

Typical information includes:

* Station ID
* Station name
* Location (latitude, longitude, elevation)
* Installation date
* Station status
* Data logger type
* Communications type
* Links to documentation

The **station ID** should be used consistently across all records.

***

### Maintenance Records

Maintenance logs document service visits and repairs.

Typical records include:

* service date
* technician or organization
* issues observed
* actions taken
* components replaced

A maintenance history helps identify recurring problems and supports troubleshooting.

***

### Sensor and Component Tracking

Sensors and mechanical components have limited service lifetimes and may be replaced periodically.

Components commonly tracked include:

* temperature and humidity sensors
* pressure sensors
* wind sensors
* rain gauges
* air quality sensors
* batteries
* data loggers

Recording installation and replacement dates helps support lifecycle planning and maintain data quality.

***

### Parts Inventory

A parts inventory tracks spare components used for maintenance and repairs.

Common inventory items include:

* sensors
* cables and connectors
* batteries
* data loggers
* mechanical assemblies

Maintaining spare parts helps reduce downtime when stations require repair.

***

### Calibration Records

Some instruments require calibration or verification.

Examples include:

* rain gauge calibration
* distance sensor reference measurements
* sensor verification checks

Calibration records should include the date, method used, and technician performing the work.

***

### Station Documentation

Each station should have associated documentation such as:

* station metadata form
* installation checklist
* site photos
* maintenance notes
* calibration records

These records provide the operational history of the station.

***

## Minimum Information for Each Station Record

Each station should have a record containing basic operational information.

### Station Identification

* Station ID
* Station name
* Project or network name
* Station type

***

### Location

* Latitude
* Longitude
* Elevation
* Datum
* Site description or nearest landmark

***

### Installation Details

* Installation date
* Installation technicians or organization
* Site access notes
* Links to station photos

***

### Site Access and Point of Contact

Station records should include contact information for both the **site owner** and the **network operator**.

Typical fields include:

* site contact name or organization
* phone number and email
* network operator or technical contact

Maintaining contact information helps coordinate maintenance visits and resolve site access issues.

***

### System Configuration

* Data logger type
* Device ID or serial number
* Communications type
* Power system type
* Sensors installed

***

### Operational Status

Typical station status categories include:

* Active
* Offline
* Maintenance Required
* Under Repair
* Decommissioned

***

### Maintenance and Calibration History

Station records should link to:

* maintenance logs
* sensor replacement records
* calibration records

***

### Station Risk Notes

Recording site-specific risks helps support long-term maintenance planning.

Examples include:

* flooding risk
* wildlife interference
* vandalism or public access
* vegetation growth
* snow or ice accumulation
* salt spray or corrosive environments

## Example Station Record Layout

The example below illustrates how a station record might appear in a spreadsheet or database.

| Field             | Example                            |
| ----------------- | ---------------------------------- |
| Station ID        | PAWS-CO-001                        |
| Station Name      | Boulder Creek Station              |
| Latitude          | 40.0150                            |
| Longitude         | -105.2705                          |
| Elevation         | 1625 m                             |
| Install Date      | 2025-06-12                         |
| Status            | Active                             |
| Site Contact      | Boulder County Parks               |
| Technical Contact | NCAR / COMET                       |
| Data Logger       | Particle Boron                     |
| Communications    | Cellular                           |
| Power System      | Solar + Battery                    |
| Sensors           | Rain Gauge, Wind, Radiation Shield |
| Last Maintenance  | 2026-02-18                         |
| Station Risks     | Seasonal flooding                  |
| Station Folder    | /Stations/PAWS-CO-001              |

This type of record provides a clear reference for the **deployment, configuration, and operational status** of each station in the network.
