I've examined the ALI data versus the Hyperion data. ALI and Hyperion both have 30 m spatial resolution. Ali has wider swath and also wider spectral bands and does not provide continuous coverage across the full spectrum from 0.4 - 2.5 µm.
On behalf of the 54 students, faculty and staff that have worked in volcano remote sensing at UAF/GI over the last 25 years as part of AVO, Peter and I would like to thank all of you and the USGS for your support, guidance and funding during that time. However, due to changing funding priorities as a result of budget cuts within the USGS, there will no longer be public support for volcano remote sensing at UAF/GI as part of the Alaska Volcano Observatory. As a result, at the end of the cooperative agreement and public funding that supported remote sensing (May 17th), we have password protected the access to all of the volcano remote sensing webtools (at avo.images.alaska.edu/tools/) and the Puff volcanic ash tracking model (at puff.images.alaska.edu). The tools will be accessible to customers and data providers of V-ADAPT (Volcanic-Ash Detection, Avoidance and Preparedness for Transportation), a project and startup company in partnership with UAF/GI.

RGB combinations of the different ALI for May 16, 2013. Note as one goes to longer wavelengths and closer to the peak wavelength on the Planck curve for hot targets, the flow becomes more enhanced. This can be seen in the zoomed in image for the Band 7,5 and 5p with wavelengths at 2.215, 1.65 and 1.25 μm.
