data_available data_available queries the IRIS DMC database to find availability of waveform data or metadata as specified by the URL and query parameters and displays the information graphically. If the query results in greater than 200000 rows returned, or the query takes too long, a diagnostic followed by this message is displayed and the user should edit their request (url and parameters) to return a smaller result set and reload the web page to resubmit the query.
Usage: http://www.iris.edu/data_available/[network|virtual network|help]/[station]/[location]/[channel]?param1=value1¶m2=value2... '*' may be used to wild card a network, station, location, or channel (but not in virtual network) '--' may be used to specify a blank location Either network or virtual network must be specified or this message will be displayed Hint: Parameters may be edited and the web page reloaded to requery with new parameter values. Hint: Virtual network queries take longer and a shorter time window may be needed for a query to return.
Parameters: help - display this message timemewindow=YYYY[/MM[/DD]]-YYYY[/MM[/DD]] - required (except for help), time window to query byday=on|off - optional, if on, group by day, default on if start/end different day or bynet is on, otherwise off bysta=on|off - optional, if on, group by station, default on if station not fully specified or bynet is on, otherwise off bynet=on|off - optional, if on, group by net, default on if network not fully specified, otherwise off quality=[D|R|Q] - optional, data quality to query, ignored if meta=on, default all meta=on|off - optional, if on, metadata will be queried instead of waveforms, default off both=on|off - optional, if on, both metadata waveform data will be queried, default off showquality=on|off - optional, channel names include channel quality, default off Overlaps will be shown only if byday, bynet, and bysta are all off. As a special case "NOW" may be used to indicate the current day for both the start and end times, e.g. timewindow=NOW would set the start and end boundaries to the current day. If the end date is omitted is is assumed to be the same as the start time, for example timewindow=1999/1/1 would be interpreted as (1999/1/1-1999/1/1) i.e. operating on that specific day. If the month and/or day is omitted from the time window start date the earliest month and/or day will be assumed, for example a start date of 2000 will be interpreted as 2000/01/01. If the month and/or day is omitted from the time window end date the latest month and/or day will be assumed, for example an end date of 2000 will be interpreted as 2000/12/31. The title and stream names in the report and graph on the resulting display reflect the parameter settings in this way: Title like "Metadata (~M)..." => meta=on Title like "Meta (~M) and Waveform Data..." => both=on Title like "...By Day..." => byday=on Title like "...Quality='X'..." => quality=X Stream channels like "*" => bysta=on Stream stations like "*" => bynet=on Warning: If the query is for waveform data and data for a stream is missing from the archive entirely for the timewindow specified, the stream will not be shown at all.
Examples: For each station in UU, show data available by station by day for year 2001: http://www.iris.edu/data_available/UU?timewindow=2001-2001 For UU, show data available by net by day for year 2001: http://www.iris.edu/data_available/UU?timewindow=2001-2001&bynet=ON For each station in _GSN, for BHZ channels, show days by station in January 2007 with archived data: http://www.iris.edu/data_available/_GSN/*/*/BHZ?timewindow=2007/01 For each station in ZF for start of 2007 to end of 2009, show days by station with archived data: http://www.iris.edu/data_available/ZF/*/*/*?timewindow=2007-2009 For network II,station AAK, for year 2007, show days with archived data: http://www.iris.edu/data_available/II/AAK?timewindow=2007" For IU, for year 2007, show days by station with metadata: http://www.iris.edu/data_available/IU?meta=on&timewindow=2007
