摘　　要：极轨气象卫星1级遥感数据是遥感信息定量应用的基础,了解影响1级遥感数据完整性和时效性的异常现象并在最短时间内进行问题的定位和处理,可以在最大程度上保障该数据的质量。以FY-3B卫星为研究对象,根据国家卫星气象中心多年积累的运行经验,对FY-3B1级数据的质量问题进行了分类,然后从问题现象、问题原因的快速定位和处理方法等方面对1级数据的质量保障技术进行了研究。最后基于研究结果提出了地面应用系统的改进建议,从而进一步提高1级数据的质量。Level 1remote sensing data of polar meteorological satellite are the basis of quantitative application of remote sensing information,which can ensure the data quality at the most extent when the abnormal phenomenon of affecting the integrity and timeliness of level-1remote sensing data is known,and the abnormal problem is located and solved as fast as possible.Taking the FY-3Bsatellite as an example,with the operating experiences accumulated by the National Satellite Meteorological Center for many years,the quality problems of FY-3Bare classified,and then some quality assurance technologies are studied,aiming at problematic phenomena,reason locations,and solutions.The findings provide proposals for the ground application system to further improve the quality of level-1data.
