How does the app determine WBGT
The app takes hyperlocal (less than 2.5km resolution) weather data that includes air temperature, relative humidity, solar irradiance, angle of the sun, cloud cover, wind speed, atmospheric pressure, and dew point then uses this data in complex mathematical algorithms that have been developed by the NOAA/NWS and Ph.D.s in meteorology.
Where do you get your weather data?
Data is sourced from the world’s most advanced weather datasets including: weather station data, NASA MODIS Satellite data, precipitation radar, weather models, RTMA, multi-sensor satellite based precipitation (NASA GPM/TRMM), the MERRA2 and ERA5 re-analyses, the GLDAS re-analysis (Agro API), and the Viasala lightning network.
Do you have an API?
No. Our software is unique and patent pending. You can only get these services through our app.
Is the WBGT accurate
Yes. In a data set of over 20,000 unique readings from May to November, WBGT calculated from weather parameters were routinely within 1 degree Celsius of WBGT using a gold standard WBGT device. https://econet.climate.ncsu.edu/wp-content/uploads/2021/05/WBGT.pdf
Does it work on artificial turf?
Yes. Contrary to popular belief, the playing surface does not change the WBGT to any appreciable degree.
