1 Min Vis Satellite: Normal image vs. parallax-corrected image

In addition to the 1 minute visible satellite imagery, we also had access to a parallax-corrected version of the product this week. It was interesting to compare the two images.

Below are 2 images centered over northern Alabama. There are several overshooting tops apparent on developing cells. Comparing the locations of the centers of the overshooting tops, I found that the the regular and the parallax-corrected images differed by around 8-10 miles. This could make a significant difference if a forecaster was using an overshooting top to try to center a warning track.

Note: I also discovered today that overlaying lightning flash density from the pGLM network on top of the satellite imagery was a nice display. In this case, you can see that the higher flash densities better correspond to the overshooting tops on the parallax-corrected image. - JP
