MIL-STD-810G Method 501.5 high-temperature diurnal cycle data. Provides hourly (24-hour) ambient temperature, ambient relative humidity, induced temperature, and induced relative humidity for two hot climatic design categories: A2 Basic Hot (Table 501.5-II) covering most of the world's hot regions including SW US, Saharan Africa, and SW Asia (ambient peak 43 C, induced peak 63 C), and A1 Hot Dry (Table 501.5-III) covering the most extreme desert environments including interior SW/SC Asia (ambient peak 49 C, induced peak 71 C). Induced conditions represent storage and transit in non-ventilated enclosures with solar loading.
