Search Sites

The Search Sites form lets you search for sites with instruments, using several parameters. You can search for sites by name, in a latitude-longitude bounding box, dates, and with many other choices. The items to query on are chosen when a new GSAC is implemented, from among fields (columns) in the database which the GSAC reads.

Here is part of a typical GSAC Search Sites form.

The free form text search fields (e.g., "4 Char ID", "Site Name") support wildcarding with "*". So, for example, in the above image the search will result in any sites that begin with "P". You can of course search for a single site, by name. If you wish to search for all sites, leave the 4 Char ID box empty; do not use the "*" character alone.

You can search with other search criteria, including typically date ranges and geographic bounds. The bounds are specified with a north latitude / west longitude / east longitude / south latitude. West Longitude may be negative, or may be simply a smaller positive longitude than the east latitude.

You can easily switch to the Search Files form. Click on the "File Search Form" icon. All site search criteria specified to Search Sites will be included in the Search Files form.
