Just a few weeks remain to send in your results for our climate survey, including your contrail observations.
The survey, which was launched in spring 2011 in partnership with the Met Office, will draw to a close on 31 March 2014.
Activities 1, 2 and 3 from the survey will come to an end as Met Office experts analyse the results you have sent in during the last three years, including more than 3,200 full surveys and a staggering 23,000 contrail observations.
The findings from these results will be published on the OPAL website later this year.
But you’ll still be able to take part in our thermal comfort activity (PDF, 264KB) to help us learn about how we could be adapting to our climate, and find a wealth of information about weather and climate on our website.
With the UK marking Climate Week from 3-9 March, there’s never been a better time to get involved, complete your OPAL Climate Survey and send the results to our experts.
