In-Depth Information
incoming solar radiation is measured using the Licor Pyranometer at 2 m (6.5 ft)
above the ground. Daily air temperature and maximum and minimum temperatures
are measured at a height of 15 cm (6 inches) above the ground using a thermistor.
Relative humidity is the ratio of the actual amount of water vapor to the amount of
water vapor the atmosphere can potentially hold at the given air temperature, and
which was measured using a humidity sensor sheltered in an enclosure located 1.5 m
(4.92 ft) above the ground. It is expressed as a percentage. The daily average of wind
speed and wind direction is measured 2.0 m (6.5 ft) above the ground, using three-cup
anemometers and a wind vane. The location map of the CIMIS Santa Monica Station
is given in Fig.
