It can take time to wade through the huge number of results from a Google search. A useful search technique to narrow your Google search to the most credible and relevant sources is to add a site limiter to your search string. Site limiters instruct Google to bring back results from only the URL's you enter. For example, if you would like to look for results from U.S. government websites, you could search:
ozone depletion potential data site:.gov
If a specific organization publishes data, try searching their website or using Google to search the organization's website, for example:
