Location
The weather station is 4km east of Tapu which is on the west coast of the Coromandel peninsula. The NZ map grid reference is 2737543, 6464971 (36° 59.3' S, 175° 32.9' E). Click here to see a map
Technical details
The anemometer is mounted on a pole 3m above the ground in the middle of a large field, and the tipping rain gauge, pressure, temperature, humidity, solar radiation and UV sensors are mounted at the same location 1.2m above the ground.
The rain bars on the graphs correspond to rainfall within a ten minute period and the maximum sensitivity is about 0.2mm. Many of the early morning bars do not correspond to rainfall, but one 'tip' worth of condensed dew.
The temperature is the average over the 10 minutes prior to the time specified . The maximum and minimum temperatures refer to the maximum and minimum temperatures measured since midnight.
The weather information is acquired using a Davis Vantage Pro2 weather station and their WeatherLink computer interface. Further details of the equipment can be found on Davis's site here . The data is extracted and and displayed with code written in Visual Basic in Excel.
Solar radiation
"Solar radiation" is technically known as Global Solar Radiation, a measure of the intensity of the sun’s radiation reaching a horizontal surface. This irradiance includes both the direct component from the sun and the reflected component from the rest of the sky. The solar radiation reading gives a measure of the amount of solar radiation hitting the solar radiation sensor at any given time, expressed in Watts per square meter (W/m2). The value logged is the average solar radiation measured over the archive interval, 10 minutes.
UV index
The UV Index (UVI) is a simple measure of the UV radiation level at the Earth's surface. It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. The higher the UVI, the greater the harm and the less time it takes for skin to burn. For further details about the UV index go to the NIWA Science site
