Linear regression of relative and absolute humidity collected with handheld thermo-hygrometers and continuous data logging instruments from March – June 2012. Single-point relative humidity measures were collected by recording an instantaneous reading from the handheld thermo-hygrometer 5 minutes after the instrument was powered on. Absolute humidity was derived from relative humidity and air temperature readings from handheld and data logging instruments. Single-point measures were matched by date and time to continuous monitoring data. Continuous readings were averaged from data loggers for 30 minutes (a & c) and 12 days (b & d).
