SUMMARY
This discussion centers on the accuracy of temperature measurements, specifically distinguishing between shade temperatures and those taken under direct sunlight. Shade temperatures, measured in ventilated white shelters known as Stevenson Screens, are consistently lower than direct sunlight readings, which reflect the thermometer's temperature rather than the air temperature. Official measurements are taken at 1.5 meters above ground, and while there is no specified ventilation rate for these shelters, forced ventilation options exist but are rarely used. The discussion highlights the importance of understanding the conditions under which temperature data is collected, as meteorological temperatures are influenced by both true air temperature and wind speed.
