Accessing the Data

Guidance for accessing 3D-PAWS data through CHORDS and Grafana, including data flow, verification, and basic troubleshooting.

Overview

3D-PAWS stations transmit environmental data through cloud services for viewing, analysis, and integration into observation systems.

---

Data Flow

Sensors → Data Logger → Network → CHORDS → Grafana

---

Viewing Data

Platform	Purpose	Key Features
CHORDS	Storage and access	Time-series data, API endpoints, external integration
Grafana	Visualization	Real-time dashboards, historical analysis, customizable views

---

Common Tasks

• verify data is being received

• check timestamps and update frequency

• review sensor values against expected ranges

• confirm consistent data updates

---

Data Quality Checks

Compare observations to expected conditions:

Sensor	Expected Behavior
Temperature	Within local diurnal range
Pressure	Consistent with nearby stations
Rainfall	Matches observed precipitation events
Wind	Reasonable speeds and directions

→ See Site Selection for siting-related issues.

Troubleshooting Data Issues

If data is missing or incorrect:

1. check data logger connectivity

2. verify power system (battery and solar)

3. inspect sensor connections

4. confirm configuration settings

→ See Troubleshooting for detailed guidance.

Summary

Accessing data allows you to verify system performance and ensure observations are accurate and usable for analysis.
