GOES-11 is the last of the current GOES series to have the 12.0 \u00c2\u00b5m IR channel on the imager instrument package, which allows the calculation of such a “split window” IR difference product for volcanic ash detection. Once GOES-11 is replaced by either GOES-13 or GOES-14 as the operational GOES-West satellite, the geostationary volcanic ash detection ability will be greatly diminished over the eastern North Pacific Ocean…until the launch of the Advanced Baseline Imagery (ABI) on the GOES-R satellite.<\/p>\n
