摘要
冰云是影响全球能量平衡、气候和天气变化的重要因素,识别冰云研究意义重大。利用葵花-8(Himawari-8)的2 km近红外第11波段和热红外第14波段数据及1 km MYD06云相态产品数据,采用代码调试,试图研究了基于亮温的Himawari-8的冰云算法,经过代码调试和验证得出Himawari-8的冰云算法。结果表明:Himawari-8云相态中冰云的初步算法为:BT_(11)<285且BTD_([8.5-11])>-1。用2015年12月29日的Himawari-8冰云数据与MODIS数据的云相态产品MYD06数据之间,使用简单匹配方法做了对比验证,结果匹配度为81.04%,匹配等级上属于匹配。
Ice cloud is importance factor of global energy balance,change of climate and weather,identification of ice cloud has significance research meaning.The ice cloud identification algorithm was studied based on band11 and band 14 in Himawari-8 and MYD06 ice cloud product data through the coding and debugging and trying research Himawari-8 ice cloud with brightness temperature. After comparing and verifying,The result showed that the initial algorithm parameters of Himawari-8 ice cloud were adjusted as follows:BT11<285 and BTD[8.5-11]>-1.0.And the verification of Himawari-8 ice cloud to MYD06 ice cloud product accuracy in December 29, 2015 is as up to 81.04%.The matching degree is a match belonging to highest degree.
