Use this form to obtain a list of monitoring stations that satisfy a specified set of conditions. All search fields are optional. After making your selections, click the SEARCH button to view a list of stations that satisfy ALL the conditions you specified. You may then choose a particular station to inspect its metadata, or download the metadata for all stations in the list in one of several formats.
In general, specifying value(s) in more fields will yield a list with fewer stations; conversely, specifying value(s) for fewer fields will produce a list with more stations.
Once you have reviewed your initial search results, you may find it necessary to adjust your search selections several times in order to zero in on the stations of greatest interest to you.
Be aware that the database records of many monitoring stations are incomplete, with blanks in one or more metadata fields. Unless stated otherwise, a blank in a particular field will preclude a station from being included in the results list when a search value has been specified for that field.
If you are primarily interested in locating monitoring stations in a particular geographic area, you may find that it is more convenient to use the interactive map of monitoring stations to perform a geospatial search.
