摘要
海雾是影响海上活动的重要因素,对海雾进行检测对于人们的海上运输、科研等具有重要意义。本文采用同步匹配的CALIOP(Cloud-Aerosol Lidar with Orthogonal Polarization)和CPR(Cloud Profiling Radar)资料以及MODIS(Moderate Resolution Imaging Spectroradiometer)数据对25°N^42°N、118°E^128°E东中国海区域2007—2016年10年间60次海雾案例进行了观测对比和分析研究。采用CPR数据进行了云分类分析,给出了CPR数据资料检测海雾的方法。对于存在高空多层云或厚云遮挡的海雾,以及低空厚云/雾的检测,分析了采用CPR和CALIOP数据的优缺点。研究表明,CPR海雾探测可作为CALIOP海雾探测的补充,二者结合有较强的互补性,对于海雾遥感检测具有一定的实际应用意义。
Sea fog is an important factor affecting marine activities,and the detection of sea fog is of great importance to people's maritime transportation and scientific research.For the 60 sea fog cases occurred during in 10 years from 2007 to 2016 in the East China Sea from 25°N to 42°N,118°E to 128°E.The observation susing colocated CALIOP,CPR and MODIS data are compared.CPR data are used for cloud classification analysis,and the method of sea fog detection based on CPR data is given.The advantages and disadvantages of using CPR and CALIOP data are analyzed for the detection of high altitude multilayer clouds or thick cloud covered sea fog and thick low cloud/sea fog.The result shows that CPR sea fog detection can be used as a supplement to CALIOP sea fog detection,and the combination of the two has strong complementarity,which is of practical significance for sea fog remote sensing detection.
