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

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.
