This page provides many of the links to the various climate-related data sources. If you need additional information on what they contain, simply click the link. If you know of additional sources of data that should be added to the list, please leave a comment or send an email to one of the email addresses contained in the Contacts page.
Unless stated otherwise, we do not make any representation regarding to the fitness of these data. Please notify us, if you think any of these data sources are faulty so that we may look into the matter. Those data sources that have been considered questionable will be immediately followed by an information source explaining why there may be a problem with the data. These explanations will be preceded by dashes to identify them as information questioning the validity or reliability of the data source.
