datetime atmosphere Actual None
air_pressure numeric Barometric Pressure

Measured using a barometer mounted inside the enclosure that houses the air temperature sensor. It is reported in millibars, where 1,000 millibars is the average air pressure at sea level. Changing pressure often indicates a coming change in the weather. Increasing pressure is associated with clearing skies. Decreasing pressure is associated with increasing cloudiness, and possibly an approaching storm.

millibar atmosphere Actual None
air_pressure_result_value_qualifier text Air pressure result value qualifier

A result value qualifier is a code field to identify measurements outside of the sensor calibrated detection range. "ADL" is a measurement above the detection limit and "BDL" is below the detection limit.

Additionally, field equipment error code "FEF" is given when the sensor or station is faulty and producing problematic data along with probably bad data code "prob_bad" when data is recognised as unusual during quality control that forms part of a feature that is probably inconsistent with real phenomena.

NA atmopshere Actual None
Photosynthetically_Active_Radiation numeric PAR

The intensity of the part of sunlight that plants can use to support new growth, and also the wavelengths of light that our eyes are sensitive to. It is measured on a small white disc that records the sum of light falling directly from the sun, and light scattered by the sky and clouds. It is reported in a unit called a micro-Einstein.

air_temperature numeric Temperature

We report temperature in the shade, in Centigrade degrees. It is measured using an electronic thermometer shielded from direct sunlight, mounted inside an enclosure with louvered walls to allow free air flow past the sensor.

relative_humidity numeric RH

The amount of water vapour in the air reported as a percentage of the amount that would saturate it at the air temperature. Warmer air can hold more water vapour than cooler air.

NA atmosphere Actual None
Precip text Rain

Reported in millimetres accumulated every 15 minutes in a gauge set about 1 m above the ground. Rain falling into a 6-inch diameter funnel drips onto a one of a pair of “buckets”, mounted on a teeter-totter. When one bucket is filled, the teeter-totter flips, the first bucket is emptied and rain then drips into the other “bucket” until it is filled, and so on. Each flip is equals 0.2 mm of rain.

NA atmosphere Actual None
wind_speed numeric Wind speed

Measured using a spinning anemometer mounted on the wind vane at the top of the tower, about 3 m above the ground. We report the average speed for every 15 minute period, in meters per second.
