Air temperature of 13.7°C recorded at Woodanilling weather station, 5:05am Sat 18 November 2017.

Measured with a platinum resistance probe which offers reliable, linear calibration. The probe is at a standard height of 1.25m, mounted in a radiation shield. The shield is to remove the effect of solar radiation.

Air temperature is a measurement of how cold or hot the air being measured is.

Specifically, temperature describes the kinetic energy, or energy of motion, of the gases that make up air. As gas molecules move more quickly, air temperature increases.

Air Temperature affects the rate of evaporation, relative humidity, wind speed/direction and precipitation patterns and types such as whether it will rain, hail or snow etc.
Soil temperature of 18.6°C at 4cm depth, recorded at Woodanilling weather station, 5:05am Sat 18 November 2017. 4cm is a typical seeding depth.

Soil Temperature is a measurement of the warmth in the soil at a given depth.

Many biological processes, including seed germination, plant emergence, microbial activity, and soil respiration are driven or influenced by soil temperature.

Relative Humidity of 93.3% recorded at Woodanilling weather station, 5:05am Sat 18 November 2017.

Measured by a capacitive element at 1.25m. This is a widely used type and provides an electrical signal that is proportional to the amount of water vapour in the air. It is containded within a radiation sheild which removes the effects of solar radiation on the measurements.

Relative Humidity indicates how close the air is to saturation. It is a measure of the amount of water in the air compared to the maximum amount of water the air can absorb, expressed as a percentage.

When Dewpoint and Air Temperature are both the same, air cannot absorb any more moisture. It is fully saturated, the relative humidity is 100 percent and the resulting condensation leads to fog, frost, clouds or rain.

Humidity forms part of evaporation estimates and is used in crop growth and disease models.

Dewpoint of 12.6°C recorded at Woodanilling weather station, 5:05am Sat 18 November 2017.

Dew points indicate the amount of moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature.

Dewpoint temperature is never greater than air temperature. When the Air Temperature and Dewpoint are the same, Relative Humidity is 100% and moisture must be removed from the air. This is accomplished through condensation which results in the formation of tiny water droplets that can lead to fog, frost, clouds, or rain.
Rainfall total of 0mm from 9am today recorded at Woodanilling weather station, 5:05am Sat 18 November 2017.

The rain gauge is a tipping bucket type, providing 0.2mm of rain per tip. The gauge is self-emptying and is the same type used by the Bureau of Meteorology (BOM).
Solar measurement of 6 Watts per Square Meter recorded at Woodanilling weather station, 5:05am Sat 18 November 2017.

Solar radiation is measured as incoming global solar that is mostly in the visible spectrum. It is a combination of direct-beam and diffuse radiation.

The probe is a thermopile, which is a set of thermocouple junctions connected together. The sensing surface is painted black and is mounted horizontally.

Solar radiation can be used for a range of energy-related work, and in agriculture is used in crop growth models and to estimate evaporation.

Readings from 3m height over 60 second period prior to 5:05am Sat 18 November 2017 at Woodanilling weather station.

Wind is coming from 99.86° (approximately E) at an average speed of 4.03km/h.

Highest gust was 4.86km/h.

Wind speed and direction are measured with either a cup and vane probe, or with a sonic anemometer. Both probe types provide wind speed and direction (as an azimuth direction, ie: easterly wind = 90 degrees, etc.), but the sonic has no moving parts and no bearings that can wear out.

Wind is used in evaporation calculations, and is a key reference for spraying decisions. It is also an important measure in extreme weather events such as bushfire conditions

Evaporation is the amount of water which evaporates from an open pan called a Class A evaporation pan. Measurements are made by the addition or subtraction of a known amount of water.

Data displayed is from midnight (12am) through to 11.59pm of the current day.

Delta T is an important indicator for acceptable spraying conditions. It is indicative of evaporation rate and droplet lifetime. Delta T is calculated by subtracting the wet bulb temperature from the dry bulb temperature.

When applying pesticides, Delta T should ideally be between 2 and 8 (the green band on the graph). Marginal conditions of 0-2 and 8-10 are shown as the yellow bands on the graph. Measurements above 10 are generally unsuitable for spraying.

The Australian Government Bureau of Meterology provides a publication to help assess weather conditions for spraying(PDF 593 Kb).
