Abstract
Combined with the spaceborne lidar active observations???an Arctic summer cloud detection model is studiedhere based on the data from the FY-3D/MERSI-II???FengYun-3D/Medium Resolution Spectral Imager-II???.By using prob???ability density function analysis method and introducing loss rate to optimize the correlating thresholds???an infraredcloud detection model for the Arctic summer is developed based on the confidence levels.The validation results revealthat the cloud detection results are highly consistent with the matched spaceborne lidar observations.The high confi???dence levels basically represent the cloudy pixels???while the low values correspond to the clear ones.The case studyshows that the cloudy pixels is100% consistent with the pixels of the confidence level higher than0.8.When the confi???dence level is lower than0.2???10.15% of the cloudy pixels are still misjudged as clear pixels???which are primarily sin???gle-layer clouds with the cloud top heights between4and6km.This may be caused probably by the cirrus clouds???which needs further study
