Collecting Weather Data

Have you set up your weather station correctly? Perhaps you would like to check by looking at Setting up your Weather Station.
Reading scientific instruments can be quite difficult. Look at the hints on the various pages to help you to be accurate.Use the links in the text or the page links on the right. Don't forget that these skills will help you in Mathematics, Science, Geography and your everyday life!

When to Collect your Data

Weather data needs to be collected at around about nine o'clock GMT (Greenwich Mean Time). This is important to make your data comparable with other sites' data. It would be ideal to collect data on Saturdays and Sundays, but if this is not possible it cannot be helped. At one school, weekend and holiday weather data is supplemented by a keen amateur weather watcher. If you have automatic equipment this problem can easily be remedied.

Data Collection Sheet

The data needs to be filled in on a standard raw data sheet. One sheet is used for each month. This can then be checked and typed into a spreadsheet document at the end of the month. It is fun to display the data for the rest of the school. Put it on a special blackboard or simply pin up a data sheet. See a raw data sheet and instructions on the right.

Reading Temperatures

Go to the temperature page to see instructions on how to read thermometers.

This image shows a maximum and minimum thermometer.

Working out the Humidity

On the humidity page you will learn to measure the moisture in the air.

The image shows the dry and wet bulbs which can be used for this task.

Air Pressure

You will find out on the air pressure page how to read an air pressure instrument called a barometer.

A barometer can be seen on the right.

Wind Measurements

The wind measurement page has details about the different wind strengths and the significance of wind direction.

The image on the right is just one type of instrument for measuring wind strength.

Recording Cloud Data

On the cloud page learn cloud names and how to record the amount of cloud in the sky.

When you know how to identify clouds you will be amazed how many different types you see!

Measuring Precipitation

The precipitation page will show how the daily rainfall can be accurately measured. Where you put your rain gauge and the units you use as measurements are both important.

It also explains about the other forms of preciptation.

The rain gauge in the photograph is just one sort that can be easily purchased.

Using ICT

Not everybody can use ICT to help them with their data collection. There are, however, lots of devices which could be interesting to use. Go to the ICT page if you would like to see some of them. You may have some of these things at school.

The instrument in the image can measure the current, maximum and minimum temperatures in two locations.
