The range of air temperature over the specific measurement periods was small (20.6 °C to 24.4 °C) with a mean of 23.1 °C.
Relative humidity was moderate to high (mean at 79%) and also
had a narrow range, varying from 71% to 85%. Although all survey days
were sunny, the changing solar angle and surrounding obstructions
caused global horizontal solar radiation to be more variable. Wind speeds
were low, varying between 0.3 and 3 m s−1
, with a mean value of
1.5 m s−1
. There was no significant topographical difference between the
two sites, as both of them are open and exposed to the wind.
