  <dc:description>&lt;div class="hlFld-Abstract"&gt;&lt;div class="abstractSection abstractInFull"&gt;&lt;p&gt;We introduce a passive noise suppression technique, based on the τ −&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;transform. In the τ −&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;domain, one can separate microseismic events from surface noise based on distinct characteristics that are not visible in the time-offset domain. By applying the inverse τ −&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;transform to the separated microseismic event, we suppress the surface noise in the data. Our technique significantly improves the signal-to-noise ratios of the microseismic events and is superior to existing techniques for passive noise suppression in the sense that it preserves the waveform.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;div class="hlFld-Fulltext"&gt;&lt;p&gt;We introduce a passive noise suppression technique, based on the τ −&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;transform.
