Validation Study of FY-3A-TOU Total Ozone Using Ground-based Data

  • 摘要: 通过地基臭氧总量观测, 对风云三号(FY-3A)气象卫星TOU (2009年7月至2013 年12月)臭氧总量开展检验分析. 结果显示, TOU臭氧总量与地基测值之间的线 性相关系数达到0.95以上, 相对差别(RD)为(-0.16±4.3)%. 赤道地区 RD随地基测值的上升明显,太阳天顶角(SZA)为70° 以上时TOU臭氧总 量明显下降, 75°~85°有-4%~-10% 不等的降幅. 云量变化(0~100%)或云高变化(1~15km)对RD的影 响在±2%以内. RD随着吸收性气溶胶(AI为正值)有-2%~-5%的 变化, 在南半球中纬度地区明显. TOU与地基Dobson, Brewer及SAOZ光谱仪测值 的RD分别为(0.6±0.17)%, (0.05±0.2)%, (0.04±0.01)%. 当地基臭氧总量在200DU以下时, TOU值低于Dobson或SAOZ测值; 而在 430~500DU时, TOU 高于SAOZ 值2%~6%. TOU分别与Dobson, Brewer, SAOZ的RD对SZA (70°以下)、云量变化均不敏感, 但TOU分 别与Brewer, SAOZ的RD在云高5km以上时或随AI的增加均出现一定的趋 势特征.
