海上的大气参数是卫星遥感器进行大气校正所需的重要参数 ,而手持式太阳光度计的现场测量精度又是能否准确地获得大气参数的重要环节 ,此环节将直接影响大气参数后期数据处理的准确性与可靠性。文章以 MI-CROTOPS II仪器在 2 0 0 2年 6月 HY- 1南海海上试验与 2 0 0 4年 3月天津试验的测量数据为基础 ,针对影响海上测量的一些重要因素与关键技术进行讨论和研究。
Atmospheric parameters of the sea is an important parameter required for satellite remote sensing atmospheric correction, and hand-held photometer on-site measurement accuracy is an important part of the atmospheric parameters can be accurately obtained, this aspect will directly affect the atmospheric parameters of the post-data processing Accuracy and reliability. The article based on the measurement data of HY-1 South China Sea test by MI-CROTOPS II instrument in June 2002 and Tianjin test in March 2004, and discusses some important factors that affect sea measurement and key technologies And research.
