本文介绍了地球观测系统（EOS）的中分辨率成像光谱仪（MODIS）的热红外波段的评估和土地表面温度（LST）版本3标准产品从Terra MODIS数据检索的状态。在2000-2002年的野外活动中收集了20多个晴空案例的现场测量数据，验证了每日MODIS LST产品的准确性。在-10 ~50 ℃范围内，MODIS的地表温度精度优于1 ℃。对新版中分辨率成像分光仪LST产品生成执行代码进行了完善和改进。同时使用Terra和Aqua MODIS数据进行LST反演，提高了LST产品的质量和产品中的日特征，因为更好的时间，空间和角度的晴空观测覆盖。
This paper presents an evaluation of the Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) thermal infrared bands and the status of land surface temperature (LST) version-3 standard products retrieved from Terra MODIS data. The accuracy of daily MODIS LST products has been validated in more than 20 clear-sky cases with in situ measurement data collected in field campaigns in 2000-2002. The MODIS LST accuracy is better than 1degreesC in the range from -10 to 50degreesC. Refinements and improvements were made to the new version of MODIS LST product generation executive code. Using both Terra and Aqua MODIS data for LST retrieval improves the quality of the LST product and the diurnal feature in the product due to better temporal, spatial and angular coverage of clear-sky observations.
