Weather Data from Tamworth, Staffordshire, UK
The weather data in the files on this page is recorded at the Weather for Schools site about 7km south east of Tamworth, Staffordshire, UK. The site is in the garden of a house on a large housing estate. The site is sloping, and has walls, fences and house creating a boundary. We make no claim for accuracy, as the data is collected as a hobby. However every attempt is made to follow correct procedures where possible within the confines of the location. The data is placed on this website for other people’s interest, education and amusement. Despite any limitations we do hope that the data provided is still useful. See more about setting up a Stevenson screen on the Setting up your Weather Station page.
The data is collected each day at 9.00 GMT. Some data is also collected remotely.
The Stevenson screen on the left contains some of the weather instruments. It is a modern aluminium Metspec screen. Follow the link to read more about it. The inside can be seen below.
This picture of the site shows how every effort has been made to get the most out of the small garden. The rain gauge is as far from tall obstacles as possible. The camera was pointing north, so the door to the Stevenson screen is on the far side of the weather box. The area around the instruments is kept to grass as much as possible. The stepping mats are made of non-slip rubber, which seems to be safer in frosty conditions. It also retains less heat than concrete. The AWS (Automated Weather Station) is situated near the Stevenson screen. It has a wireless connection to its consol and a computer.
The first thing that can be observed is that the inside louvres of the screen is black instead of white. Extensive trails comparing the effectiveness of black or white have been carried out. The black colouring came out well. The instruments are - wet and dry thermometers, Maximum and minimum thermometers, and an inexpensive but easy to glance at thermometer. A dial hygrometer is also included. As near as possible the instruments are placed in the centre of the space. This gives maximum benefit of ventilation and shade.
This scientific 125mm rain gauge has been placed in a terracotta tube so that it does not get knocked or blown away. See inside it here. It also has a crown of electrical ties to stop birds from perching on the rim. It has been placed as far from other objects as possible. See more on the Precipitation page.
In the background is a cheap plastic rain gauge which is useful for seeing from inside the house.
This contains the rain gauges, the thermometer screen and two light sensors. It is wireless and has solar panels to give it power. Humidity readings are also generated here. . It has a home-made 'crown' of cable ties, and a post topper to discourage birds from perching. Any disadvantages are far outweighed by the advantages of these modifications. See more about it on the ICT page.
The top section on this mast is the wind part of the Davis Vantage Pro2. It too is wireless and solar powered. It has been placed on a mast on the highest part of the roof. Although it should ideally be higher, this is the best possible on this site. It is situated at an approximate height of 6 metres.
The lower anemometer belongs to the Instromet apparatus that can be seen on the More About ICT page. It's data is displayed on the sitting room mantelpiece.
Your Weather Spreadsheets
One of the best ways to see what sort of weather you have had is to enter the data into a spreadsheet. The graphs show when the temperature has gone up and down. It is easy to see when there was the most rain. Each weather measurement is easier to evaluate. Depending on which measurements you take each day, there are three different empty spreadsheets for you to choose from on the right.
If you are just reading the current temperature and the rainfall, you will need the basic spreadsheet.
If you are taking more readings, look at the intermediate and the complex spreadsheet and choose which is best for you.
You don't have to fill in all of the boxes. You can do what is best for you.
When you are ready load up the empty spreadsheet. Save it using different names for the months and years that you aim to record. Load up the one you need and start typing in the data. There is no need to set anything up, it is all ready for you to use. Below are some of the helpful graphs which the spreadsheets can automatically draw for you.
Explanation of features on the data chart
Date - This is recorded in the first column. This is the date of the reading. The climatological day runs from 09.00 to 09.00 GMT.
Max. T. - The highest temperature for the last 24 hours. (This is more likely to be on the previous day, particularly in the summer. However in some cases this will not be so.)
Min. T. - The lowest temperature for the last 24 hours. (This may more often be on the morning of the day of the recording. However there are cases when it will be on the previous day.)
Dry T. - The dry temperature.
Wet T. - The wet temperature.
Hum. - The humidity calculated from the dry and wet temperatures.
Press. - The air pressure reading in mB.
Wind D. - The wind direction.
Wind St. - The wind strength as measured on the Beaufort Scale.
Cl.am. - The amount of cloud cover, measured in Octas.
Cl.Ty. The main types of cloud.
C. Clear of cloud
Rain - The amount of rain collected in a rain gauge for the past 24 hours. This is measured in mm. (T = total rainfall)
Snow - The height of snow, measured in cm.
Ave. - This is the average.
Max. - This is the maximum.
Min. - This is the minimum.
