摘要 利用船载多参数拖曳式剖面测量系统走航观测获取的台湾岛东南海域叶绿素a浓度连续剖面数据,开展了卫星遥感产品精度检验研究。研究表明,由MERIS反演的叶绿素a浓度产品的平均相对误差优于30%,拖曳剖面观测可为卫星遥感产品检验提供高质量的现场观测数据,而且与船舶、浮标及其他固定平台等传统定点观测方式相比具有明显的效率优势。 Based on the in situ continuous profiling data of chlorophyll a concentration acquired by the ship-board multi-parameter towed profiling system in the southeast of Taiwan Island,ENVISAT MERIS product was validated.MERIS product overestimates the in situ chlorophyll a concentration by less than 30%.It is manifested that towed profiling system can provide high-quality in situ data for satellite product assessment and has the obvious advantage of high efficiency over traditional stationary platforms.
