Notice of RetractionA Daytime Radiation Fog Detecting Scheme Based on TERRA/MODIS Data over Land

Abstract

Weather experts increasingly concerned about the fog as a weather phenomenon. At present there are still difficulties in detecting fog because the detection threshold between fog and the clear sky surface is uncertainty, spectral features and texture features between cloud and fog is similar. This article develops a daytime radiation fog detecting scheme based on TERRA/MODIS data over land, which aimed at the separation between fog and clear sky, cloud. The detecting scheme has strong stability, high automaticity. But the detecting scheme is difficult to detect light fog, and easy to misjudge some types of clouds as fog. Therefore, algorithm should be further improved.
