Dataset: Discomfort Heat Index Duration and Intensity in Miami, FL, 1940–2025, yearly data

The dataset includes annual results of calculations related to Discomfort Heat Index in Miami, FL 1940-2025. The Discomfort Heat Index (DC) is defined in this dataset as the difference between the actual Heat Index (HI) and the Comfort Heat Index (CHI=26.6°C). This dataset applies multi-threshold framework, the lowest Discomfort Heat Index Threshold (TDC) is 0°C, the highest 8°C, and each step 2°C. The parameters analyzed are: o annual average Heat Index above CHI during the whole year (not only in summer) – HI>CHI, °C o annual maximum Heat Index during the whole year (not only in summer) - MaxHI, °C o annual duration of Discomfort Heat Index during the whole year (not only in summer) - DDC, hr/year o Discomfort Heat Index Intensity during the whole year (not only in summer) – DCI, degree-hours/year o Summer Discomfort Heat Index – DC(TDC) o Duration of Summer Discomfort Heat Index – DDC(TDC) o Summer Discomfort Heat Index Intensity – DCI(TDC) o Duration of Discomfort Heat Index above CHI on non-summer days (DDC) hr/y The term “Discomfort Heat Index Intensity” (DCI) is the difference between the actual mean Heat Index and the Comfort Heat Index (CHI = 26.6°C) multiplied by the cumulative time the Discomfort Heat Index remains above the threshold (DDC).
