Contrails over Met Office, Exeter

The Opal Climate survey is a series of four experiments designed to help people of all ages learn about man's impact on climate and climate's impact on man.

The Met Office is the lead scientific advisor on the climate survey and our climate scientists have designed the experiments and trained groups of community scientists up and down the country to enable them to teach them to others.

There are four main things to do in the survey:

  1. Spot plane trails, known as contrails, as a measure of air temperature and humidity.
  2. Watch cloud movement to record wind direction in the sky.
  3. Blow bubbles to measure wind speed and direction near the ground.
  4. Record how hot or cold you feel.

The results will be analysed by Met Office scientists.

Anyone can take part in the survey. The more people that get involved the more valuable the research becomes. The results from all four activities will be published on the OPAL website, where you can see how your findings compare to others across the country. 

You can register for a survey pack at opal@metoffice.gov.uk and for more information on the OPAL Project, which is funded by the Big Lottery Fund, visit www.opalexplorenature.org
