Indoor measurements are crucial to understanding the temperature and humidity levels in your home. The data loggers used in this study measured temperature from -20°C to 70°C with an accuracy of ± 0.35°C.

These loggers were specifically designed to withstand the indoor environment, away from sources of heat, cold, or moisture. They recorded one measurement per hour, allowing for up to 2 ½ years of data storage without overwriting memory or replacing batteries.

The data loggers were validated against a National Institute of Standards and Technology traceable instrument to ensure accuracy. This validation process took place both before and after the one-year sampling period.

To calculate the apparent temperature, the researchers used the US National Weather Service algorithm, which applies corrections for low temperature and very low and high relative humidity. However, this algorithm does not consider the effects of wind.

Here's a breakdown of the data collection process:

The researchers also calculated specific humidity from the measured dew point and outdoor atmospheric pressure using the following equations:

e = 6.11 × 10(7.5 × Td) / (237.7 + Td)

SH = 1000 × (0.622 × e) / [P - (0.378 × e)]

These equations were used to calculate daily mean temperature, apparent temperature, relative humidity, dew point, and specific humidity.
