How Do You Know if You're Exposed to Heat Stress?

Most of what we do relies on two data sets. One is based on a model called Sea Glass, it's a very long acronym which I actually don't remember right now but who's full for my don't remember? The second measure that we use is from a company called 427. They do some similar analysis of this type, but they also recognize that companies have locations in different geographies. And once you have the temperature distribution at each of these geographies, they aggregate these distributions across different geographies to come up with a single heat score for a given company.
