What channels are available and what channels should I request?

Q: What channels are available and what channels should I request?

A:  There are a number of tools you can use to get channels that are available for a given station.

An easy path is to use MDA to discover which channels are operating for a station at a particular time.  You can also check for data availability by selecting the appropriate year.  This will take you to a tool that will show the data coverage we have for that channel.

Another method is to make use of IRIS Web Services.  The ws/availability service is particularly good at helping you to narrow down which channels you can expect to get data for.  You can also search in a particular geographic area.  The output from this service can be used directly to feed the ws/bulkdataselect service to actually request the data.

There are many other ways you can discover data at IRIS DMC.  Please consult our main data page for more information.
