### DODS data downloads

DODS allows one to give a application a url and have it directly download data.
In this case the url is
**http://iridl.ldeo.columbia.edu/SOURCES/.IGOSS/.TOPEX/.UTCSR/.ssh/%5BX+Y+T+%5Ddetrend-bfl/yearly-climatology/%5BX+Y+T+%5Ddetrend-bfl/X+differences/X+partial/T+integral/Y+integral/T+integral/%5BY+%5Ddetrend-bfl/T+differences/T+integral/Y+partial/T+differences/Y+integral/dods.help**

When you give that url to a DODS client, it actually sends a url with one of the
following six file extensions: .das, .dds, .dods, .info, .ver or .help.
The extensions tell the DODS server which object to return (see table).
**Note**: Many DODS clients supply these extensions for you so you don't
need to append them (for example when using interfaces supplied by DODS or
software re-linked with a DODS client-library). Generally, you only need to
add these extensions if you are typing a URL directly into a WWW browser.

^{*}On GrADS startup, the config line should read
Config: ... DODS-enabled ...,
otherwise DODS is not installed and giving GrADS a URL will result in a
file-not-found error.
