The OPAL Climate Survey consists of four ways to help researchers investigate how human activities affect the climate. These include: Activity 1 - Contrails in the Sky: By looking for contrails (tracks left by planes) in the sky and reporting your results online, you'll help scientists test the accuracy of existing computer models that tell us where contrails should be. Activity 2 and 3 - Measuring the Wind: In Activity 2, you'll use a mirror and compass to measure the wind direction at cloud height. In Activity 3, you'll use bubbles to calculate the wind direction and speed at our height. Activity 4 - How the Weather Affects Us: You'll answer simple questions about how hot or cold you feel and the types of clothes you are wearing. This is one of five OPAL surveys across England to learn more about the state of the environment. Anyone can get involved. The studies are open to all ages and abilities, and your contribution will be important in helping scientists build up a picture of England's natural environment.
