 | Air Temperature is measured at 2 metres and 10 metres above the ground. This indicates the temperature on site and assists in determining other meteorological conditions on site and in the local area. Ambient temperature is used in determining the amount of rise experienced by a mass of air. The vertical temperature difference is used in calculating vertical air movement under stable atmospheric conditions. |

Wind Speed is measured at 10 metres with a fixed mount propeller anemometer. Hourly average wind speed measurements are displayed. Wind speed determines the amount of initial dilution experienced by a mass of air and in conjunction with other variables, the determination of atmospheric stability. Wind Direction is measured at 10 metres above the ground with a wind vane and provides the hourly average direction. The arrow of the wind rose (above) points towards the direction the wind is coming from. | Solar Radiation is a measure of the energy (KW) transmitted from the sun onto the site per unit area (m2). This is used in calculating the meteorological conditions on site, with the value used to determine atmospheric stability, various surface layer parameters and for estimating convective (day time) mixing height. Hourly Rainfall. Precipitation data is used for consistency checks in data analysis. |
