Fog detection algorithm
WebSep 3, 2024 · Both CBH and visibility measurements are averaged to 5 min time blocks, matching the blocks used by the fog detection algorithm. The cloud radar is used to retrieve fog CTH and to detect the presence of higher clouds above the fog layer, based on its vertical reflectivity profile (Wærsted et al., 2024). To retrieve CTH, reflectivity signals in ... WebFog is a difficult to predict and very local weather phenomena. With computer vision, development and movement of fog can be monitored with camera systems. Image classification algorithms can help classify the density of the fog that is present on the captured image.
