Most officials concerned with public safety have been relying on a metric called Heat Index to assess the severity of a hot weather outbreak and how it may negatively impact people and animals.
Heat Index is a mathematical derivation of temperature coupled with humidity, but, it turns out there's a much more complete metric that incorporates radiation and wind as well.
It is called Wet Bulb Globe Temperature (WBGT) and all OrangeSTEM sites report real-time as well as forecasted values of WBGT.
Some states, such as Georgia, REQUIRE WBGT to be measured and recorded before any public activity commences.
We have created an educational resource about WBGT that we recommend you check out at this link.
