摘　　要：针对我国海洋遥感定标检验技术,提出海洋水体皮温-体温模型,将海洋皮温测量精度提高至0.3℃.模型皮温数据来源于自主研制架设在南海北部PY-301石油平台上的无人值守自动多波段红外辐射系统,通过标准黑体标定、光阑校正、天空光校正,使海水皮温测量精度优于±0.5℃.基于模型分析了风速对海洋皮温和体温差值的影响,并用所提模型与Donlon模型对海洋皮温测量值进行风速修正,修正后两者偏差分别为-0.007 6±0.297 1℃和0.044 6±0.324 8℃.结果证明该模型有效且能够提高海洋皮温的测量精度.For the research of marine remote sensing calibration of China,a mathematical model of bulk-skin sea surface temperature is proposed to improve the measurement precision of skin sea surface temperature to 0.3℃.Skin sea surface temperature is measured by the self-designed automatic multi-spectral infrared radiometer system installed on the PY-301 oil platform in the northern part of the South China Sea,the measurement accuracy of the radiometer is better than±0.5℃through standard blackbody calibration,pupil correction and skylight correction.The effect of wind speed on the bulk-skin sea surface temperature is analyzed based on the model,the skin sea surface temperature is corrected by the proposed model and Donlon model,the biases of corrected results are-0.007 6±0.297 1℃and 0.044 6±0.324 8℃,respectively.Results prove that the proposed model is effective and can improve the measurement accuracy of skin sea surface temperature.
