Just wanted to share this Satellite comparison from the shallow dense fog event across South Texas this morning on Jan 20, 2014. Although the fog is visible in both images (dark green shading in GOES 11u-3.9u IR Sat Image on left), the SPoRT imagery appeared to contain more detail (large area of off-white in MODIS-VIIRS Night-time Micro RGB 1km imagery on right). The SPoRT imagery also hinted at the northward expansion of the fog with the slight purple color shading to the north of the off-white shaded fog bank. (noted by yellow arrow). The fog eventually did expand northward across eastern portions of McMullen and all of Live Oak County over the course of the next hour.
