摘要
文章利用2016年3月~2017年2月宁夏地面人工观测总云量资料和FY-2G卫星云量产品,对卫星云覆盖率和总云量两种产品的月分布、逐日变化、偏差分布以及一致率等进行了统计分析,并根据分析结果对出现误差的原因进行了详细的讨论,为FY-2G云量产品的应用和研究提供基础。
Utilizing surface observed total cloud amount data from March 2016 to February 2017 in Ningxia and FY-2 Gcloud amount products,this paper statistically analyses the monthly distribution,daily average value,deviation distribution and consistency of FY-2 Gtotal cloud amount and cloud fraction rate products.According to analyze the results,the reasons that caused the errors are discussed in detail,which could provide the basis for applying and researching on FY-2 Gcloud amount products.
