Citing web pages

The AGU reference style guide provides little information on citing web pages, so we will use a different approach adapted from the American Meteorological Society reference guide.

In your list of references, use the following format, with the data elements given in brackets. (Don't include the brackets themselves.)

[Author(s)/Authoring Organization], [year published or cited]: [Document name.] [Publisher or specific organizational office, if different from Author.] Accessed on [Date when the material was accessed for use] from [URL where available online.]

Example:

Riebeek, H., 2010: Global warming. NASA Earth Observatory. Accessed on November 7, 2013 from http://earthobservatory.nasa.gov/Features/GlobalWarming/

If the author is unknown then cite the authoring organization, and if the date of publication is unknown use the date the material was accessed (with a notation that this is the case). Example:

National Weather Service, accessed 2015: Southeast Idaho climate information. National Weather Service Forecast Office, Pocatello, Idaho. Accessed on November 7, 2015 from http://www.wrh.noaa.gov/pih/climate/descrip.php

In both cases you would cite the material in your text in the same way you would cite any other reference, e.g.,

According to Riebeek [2010], natural causes of climate change still are occurring today.

or

The region around Pocatello has a wet and windy spring [National Weather Service, 2015].

Remember that you should these types of references only if peer-reviewed references are unavailable and that you will need to fill out an evaluation sheet for each reference that is not published in a peer-reviewed journal.
