Weather Station Information


This page contains details of the weather station that records the local weather and publishes it to the Angmering Village Life web site.  In addition to the Angmering Village Life web site, this weather station is a member of the International Weather Underground web service who classify it as a Personal Weather Station within their Shoreham area.

Background Information

The weather station is physically located in North West Littlehampton (Latitude: N 50° 48 ' 36 '' ( 50.810°) - Longitude: E 0° 30 ' 35 '' ( -0.510°)). In relation to Angmering it is 0.5 miles from the parish’s SW corner, and 1.75 miles from the centre of the village.  The weather station is manufactured by Oregon Scientific (Model No.: WMR928N), and is connected to a Personal Computer running Virtual Weather Station software 24 hours a day, 7 days a week.

The weather station went 'live' and started collecting data from Saturday 13th February 2005. Various statistics can be found on the Statistics page.

 

   

Wind Speed & Direction

The weather station features a combined Wind Speed (Anemometer) and Direction (Weather Vane) sensor that transmits information back to the base station at 5 second intervals.  The wind speed is measured by the sensors in Miles per Hour. The Virtual Weather Station software captures the data, and analyses it to formulate other relevant statistics e.g. Average Guest Speed and Wind Chill (Feels Like) factors.

The instrument is located on top of the property to ensure maximum accuracy of the readings, as shown in the picture opposite.

   

Outside Temperature & Humidity

Temperature and Humidity is calculated from readings obtained from the Outside Temperature Sensor.  This sensor transmits the temperature and humidity to the base station every 10 seconds.  The data is collated by the base station and passed onto the Virtual Weather Station software (in oc), that, as with the other sensors, is processed in order to publish it to various data repositories.

The sensor is located about 3 metres above ground level, as shown in the picture to the left.

 

 

   

Rainfall

The weather station also features an electronic rain gauge, that measures the rainfall in 1mm increments.  Internally, the instrument contains a "dual tipping bucket".  The rainfall is collected and funnelled into a 'bucket'.  When 1mm of water is captured in the bucket, it automatically tips over due to the excess weight (the bucket empties, and an empty bucket is automatically positioned to start capturing the next 1mm of rain). 

The tipping of the bucket, causes a trigger to occur.  The trigger is relayed to the base station for onwards data transmission to the Virtual Weather Station software.

The sensor is located about 2 metres above ground level, as shown in the picture to the right.

 

   

Pressure

The Barometric Pressure is calculated with an indoor electronic barometer.  The information is relayed to the base station every 30 seconds.  The base station uses this information together with the Rate of Change (as well as outdoor temperature and humidity) to calculate a general forecast for the next 24 hours.

This device also monitors the indoor temperature (in oc), as shown in the picture to the left.
