Xweather Observe

Better operational decisions from quality-controlled sensor data

  • 30+ supported parameters
  • Automated quality control
  • API and dashboard access

Secure access to 30+ weather, environmental, and solar parameters from Vaisala sensors, quality-controlled and delivered via API and dashboard.

Real-time monitoring with quality-controlled data

Observations displayed in map, graph, and list views. Every measurement passes automated quality control before it reaches your systems. A 3-day weather forecast is included in the map view.

Streaming and REST APIs for every workflow

A streaming WebSocket API delivers new measurements as they arrive. A REST API serves historical data for integration into business intelligence, SCADA, and operational systems. Both APIs use standard formats and are included in the subscription.

From sensor to operational decision in four steps

01
Connect

Connect Vaisala sensors and weather stations to the Xweather Observe service. Secure cloud connection with minimal setup.

02
Ingest

Observations are ingested and quality-controlled automatically. Range, cross-parameter, step, and persistence checks run on every measurement.

03
Access

Access data through the web dashboard or integrate via streaming and REST APIs. Map, graph, and list views are available from any device.

04
Configure and act

Configure threshold alerts, user access, and notification routing. Attach action guidelines so recipients know exactly how to respond.

Visibility where it matters

Xweather Observe supports operations that depend on local weather, air quality, or solar conditions.

Weather operations

Site-specific operational monitoring

Vaisala weather stations deliver site-specific temperature, wind, precipitation, and pressure data for facility management, safety protocols, and event-based decisions. Automated QC checks incoming data before it reaches dispatch, planning, or control systems.

Solar performance

Irradiance and performance monitoring

Operators of photovoltaic installations monitor irradiance, panel temperature, soiling, and tracker alignment. Real-time and historical data supports performance ratio calculations, soiling loss quantification, and reconciliation between expected and actual generation.

Environmental monitoring

Air quality and emissions monitoring

Gas and particulate matter sensors measure pollutant concentrations in real time. Xweather Observe calculates European and U.S. Air Quality indices automatically. Threshold alerts trigger when concentrations approach regulatory or operational limits, supporting compliance reporting and community notification.

Build on Xweather Observe

Xweather Observe is the data access layer. Two products extend its capabilities for organizations that need more from their sensor investment.

Data access and monitoring

Secure access to 30+ weather, environmental, and solar parameters from Vaisala sensors. Quality-controlled observations, threshold alerts, and API integration.

Add severe weather alerting

Set up lightning, hail, wind, and gust alerts for your sites with no additional hardware. All-clear notifications reduce unnecessary downtime.

Explore Xweather Protect

Add hyperlocal forecasting

Pair your sensor observations with a dedicated machine learning model to generate a hyperlocal, calibrated forecast with confidence limits for each site.
