Note: The L1B Thermal anomaly detection scan is currently in progress, and much of the database is still being ingested. Therefore expect time gaps in the current compiled data. Also, not all thermal anomalies are necessarily volcanic: we are also detecting both natural and anthropogenic non-volcanic thermal anomalies (e.g., factories, wildfires, trash fires, etc.) that have generated flagged granules. Generally, the closer an anomaly is to the identified volcano center, the more likely it is to be volcanogenic.

This is preliminary archive scan using ASTER L1B data, however, our next refinement will be to replace these data with those derived from ASTER 09T data products.We anticipate this within the next two months pending our server upgrade. Look for greater sensitivity and more accurate hotspot geo-location.

As our operational philosophy is to provide data as quickly as possible publicly, we have opted to err on the side of transparency and completeness--regular users will be able follow along as we conduct our beta-testing online. Consequently, look for continuing updates and possible associated changes in presentation format throughout the site over the next several months.
