-  Water Vapor Channel
-   **Change from 8km to 4km horizontal resolution**
-  GOES-8/10 **12 Micron Channel 5 (Split Window)**
-   Sea Surface Temperature
-   Volcanic Ash
-  GOES-12 **13.3 Micron Channel 6 (Atmospheric/Surface Temp)**

## GOES-12 4km Water Vapor Channel

**Notes:**
Examples of the improved water vapor imagery on GOES-12 The improved spatial resolution on the water vapor images from GOES-12 is evident in comparisons with GOES-10 and GOES-8. Water vapor boundaries appear smoother on GOES-12, and small scale features such as mountain waves are better resolved. For the water vapor band, GOES-12 has 4 km detectors, as opposed to the 8 km detectors on GOES-8/11, although image differences are also due to viewing geometry and the different spectral response function widths. Image examples comparing GOES-12 to GOES-10 and GOES-8 (including a Java animation) can be viewed at http//cimss.ssec.wisc.edu/goes/misc/011119/011119.html (S. Bachmeier, T. Schmit)

- Clear-air mountain waves in water vapor imagery

**Notes:**
Clear-air water vapor image of mountain waves over Colorado and New Mexico, using MODIS data.   The two images simulate the current GOES (8km) and GOES-M (4km) water vapor imagery.  Structure and intensity of waves (associated with strong vertical motion) is much clearer in 4km imagery. Clear air turbulence is frequently associated with these features.  Two pilot reports of unexpected moderate to severe clear air turbulence were noted over Colorado on 7 April 2000.
