Widespread fog and stratus had developed across southern Alabama and western Georgia during the pre-dawn hours on 04 April 2017. After sunrise, a comparison of 1-minute interval GOES-16 and 15-30 minute interval GOES-13 visible imagery (above) demonstrated the advantage of more frequent scans to monitor the dissipation of fog and stratus. The improved spatial resolution of the GOES-16 0.64 µm “Red visible” band — 0.5 km at satellite sub-point, vs 1 km for GOES-13 — also aided in the detection of smaller-scale river valley fog features.
