Siting your weather station to obtain the rainfall data you want!
Siting your weather station to obtain the rainfall data you want! |
The Problem: | |
| You have purchased a weather station through us that allows you to measure temperature, humidity, rainfall, wind speed and barometric pressure. You are most interested in rainfall data as you use the station to gauge how much rain has fallen in your garden; however you are unsure as to where to mount the station in order to obtain the most accurate results. | |
The Solution: | |
|
It will depend on the station that you have purchased as to which setup will best suit. If you have a station such as the
IC0369
or
IC6250AU
where all the outdoor sensors are combined in the one sensor suite or the
IC0346
or
IC0348
where there are only short cables connecting the sensors to the transmitter then the station is best suited to being mounted 1.2-2m off the ground in the area where you wish to establish the rainfall level.
If you have a station such as the WS1516IT, WS2355, IC6152AU or any of the Vantage Pro 2 range that has the capability to have the anemometer (wind sensor) separated from the rest of the sensors then you have more flexibility with regards to mounting the station. If you have one of these stations we would advise setting up the rain gauge, along with the temperature and humidity sensors approximately 1.2-2m off the ground near the site you wish to establish rainfall. The anemometer can then be mounted at a higher position if desired to improve your wind speed data. The optimum height is 10m, however this is not achievable in most instances and as such mounting it on your roof above the roof line will yield the best results The reason for mounting the rain gauges at this level is to reduce the effects that higher wind speeds can have on the measurements obtained. This is due to the fact wind speeds at higher levels are significantly higher and can affect your rainfall readings. This is because wind eddies can form around the orifices and this reduces the catch of small rain drops. This problem is known as wind-induced gauge under-catch and is considered the most common and serious source of rainfall-measurement errors. Through mounting your station at these levels you will establish rainfall levels that closely correspond to the levels falling on your garden or lawn. It is also the ideal height to mount the gauge in order to most closely match the rain that has occurred in your area.
