Value of Parallax Correction

We just got started setting up our procedures in AWIPS II and got caught up in a discussion of the value of parallax correction. It is very obvious when you toggle between the two. The correction is very evident in the mid and especially the higher clouds. We're currently looking at thunderstorm anvils in the western part of Corpus Christi's forecast area. The correction removes some of the shadowing from these anvils that were projected onto the lower clouds. Also, we looked outside of the area we were focused in, up further north. The edge of the cirrus across portions of Iowa and Missouri shifted significantly between the standard visible image without correction, and the parallax corrected image. We can see where this would be most valuable with the derived products and ensuring their placement is accurate and lines up well with radar data.

In the above images, corrected is on the top and uncorrected is on the bottom.
