摘要 利用内蒙古达里湖定标与真实性检验场地的星地同步观测数据,通过辐射传输模型计算大气廓线高度、大气气体含量、水表参数和观测角度等因子的不确定性对HJ-1B热红外通道(B08)星上定标精度的影响,分析星上定标对各观测因子误差的敏感性。结果表明,回归星上黑体常温点293K和高温点328K得到的HJ-1B B08星上定标,在285.5K点的定标精度在0.84K以内,从定标角度来说,满足陆表温度反演1.0K以内对定标精度的要求,而较难满足水表温度反演0.3K以内对定标精度的要求;星上定标更适用于洁净、干燥大气和高温、高比辐射率地物目标的定标。 The precision of HJ-1B on-board calibration is analyzed based on Dali lake calibration and field validation using the uncertainty and sensitivity of atmospheric profile's height,meteoric contents,water surface parameters and satellite zenith angle.As a result,the HJ-1B B08 on-board calibration system using normal temperature 293K and high temperature 328K.It induced an error within 0.84K when used to temperature 285.5K,which means it meets the requirement of LST retrieval,but not SST.On-board calibration is more suitable for clear sky and dry atmosphere,and object of high temperature and emissivity.
