Strengths
|
|
Strengths of our study include its transparent and adaptable framework, alignment with internationally recognized ISO standards, and integration of job-specific factors including clothing, physical activity level, time spent indoors versus outdoors, and local heat or cooling sources. These factors were derived from existing datasets and refined by a panel of five experts with complementary expertise in occupational hygiene, exposure assessment and thermal physiology. The JEM is further strengthened by the use of high-resolution meteorological data from ECMWF ERA5-Land, covering 1970 to 2024, with hourly estimates of key climate variables and the ability to incorporate future updates.
