Table 3 Daily mean, standard deviation (SD), and interquartile range (IQR) of minimum, maximum, and mean temperature, and temperature variability in Atlanta from 1993–2019 by season and over the full period. The cold season is defined as November to February, the moderate season is defined as March to May and October, and the warm season is defined as June to September

From: Time-series analysis of temperature variability and cardiovascular emergency department visits in Atlanta over a 27-year period
