Table 3.2. Surface types used in archive site identification.

(11) Photographs of the station and its surrounds. Up to 4 photographs with appropriate

comments should be provided. These can convey useful information concerning the

instrument set-up and the surrounding horizon if there are significant obstructions. For

example, if a tower is found on the site, a photograph may be appropriate to show where

the instruments are located, or four pictures of the cardinal points of the compass from

the central instrument with a wide-angle camera. In a manner similar to the comments

section above, the photographs are to convey information about the station to the data

users.

The BSRN Station Description document should be updated regularly. If significant changes occur

in the instrumentation, the horizon or the ancillary measurements, corrections should be made

immediately. In a manner similar to the horizon survey, the site description should be updated

every five years.
