PURPOSE: This tool displays a comparison of the availability of continuous waveform data for a network and channel over three different time scales: yearly, monthly and daily.

USAGE:

1. Use the pull-down menus below to select a network and channel to display.
2. Click "Show Waveform Availability" to display the waveform availability plots for that network and channel.
3. Click on the bars of the resulting annual/monthly waveform availability plot to show the monthly/daily plot. Similarly, click on the monthly/daily plot to show the daily/hourly availability plot.

NOTE: Pull-down menus marked with an asterisk (*) will only show valid entries based on the choice selected for other asterisked pull-down. If there is no entry, try making your search less restrictive.
