(11) Photographs of the station and its surrounds. Up to 4 photographs with appropriate
com m ents should be provided. These can convey useful inform ation concerning the
instrum ent set-up and the surrounding horizon if there are significant obstructions. For
exam ple, if a tower is found on the site, a photograph m ay be appropriate to show where
the instrum ents are located, or four pictures of the cardinal points of the com pass from
the central instrum ent with a wide-angle cam era. In a m anner sim ilar to the com m en ts
section above, the photographs are to convey inform ation about the station to the data
users.
The BSRN Station Description docum ent should be updated regularly. If significant changes occur
in the instrum entation, the horizon or the ancillary m easurem ents, corrections should be m ade
im m ediately. In a m anner sim ilar to the horizon survey, the site description should be updated
every five years.
