Monitoring Meteorological Data in Real Time
Monitoring weather and recognizing its effects on project site conditions is an essential aspect of environmental health hazards. The Greenlight™ System can be equipped with a complete meteorological station to record and log weather information in real time. The complete weather station measures and records the following to build a comprehensive weather snapshot:
- Wind speed
- Wind direction
- Ambient temperature
- Relative humidity
- Barometric pressure
Environmental Data Tagged with Wind Speed and Direction
The Greenlight™ System automatically links every environmental data point to current wind speed and direction and adds timestamp and site location. As a result, sampling results can be identified as downwind or upwind, offsite or onsite, so that project personnel can respond and analyze site activities as conditions change. When there is an alarm notification from a field sensor or detector, the System knows which station is upwind to determine if there is background data coming on site.
- Weather data displayed on-screen includes
- Instantaneous instrument readings
- Rolling, time-weighted averages (TWA)
- Adjusted readings subtracting upwind/background from measured results
Modeling Airflow Patterns with Multiple Stations
Depending upon site needs, the Greenlight™ System can also include additional mini-weather detectors at field station that measure only wind speed and direction. These are very useful for large or complex project sites where a single weather station cannot provide an accurate picture of airflow patterns. The complete picture of site conditions from all weather stations is displayed in Map View by a colored contour map.
