中分辨率成像分光仪在中等分辨率地球观测方面取得了重大进展。提高250米和500米地面观测的空间分辨率和改进光谱带的位置提供了新的遥感机会。美国航天局已投资开发改进的中分辨率成像分光仪算法，这将为全球变化研究提供新的数据集。地表反射率是MODIS的关键产品之一，并用于开发几种高阶陆地产品。地表反射率算法建立在高级甚高分辨率辐射计（AVHRR）和SeaWiFS算法的基础上，利用了中分辨率成像光谱仪的新传感能力。通过去除水蒸气和气溶胶效应进行的大气校正提供了对以前的粗分辨率产品的改进，并为新的时间序列提供了基础，该时间序列将延伸到NPOESS一代成像仪。本文总结了第一次评估的中分辨率成像光谱仪表面反射率产品的准确性，与其他数据产品相比，并在中分辨率成像光谱仪仪器的性能，因为发射。中分辨率成像分光仪的地表反射率产品将为量化全球环境变化提供重要的时间序列数据集。(C)2002年爱思唯尔科技有限公司All rights reserved.
The MODIS instrument provides major advances in moderate resolution earth observation. Improved spatial resolution for land observation at 250 and 500 m and improved spectral band placement provide new remote sensing opportunities. NASA has invested in the development of improved algorithms for MODIS, which will provide new data sets for global change research. Surface reflectance is one of the key products from MODIS and is used in developing several higher-order land products. The surface reflectance algorithm builds on the heritage of the Advanced Very High Resolution Radiometer (AVHRR) and SeaWiFS algorithms, taking advantage of the new sensing capabilities of MODIS. Atmospheric correction by the removal of water vapor and aerosol effects provides improvements over previous coarse resolution products and the basis for a new time-series, which will extend through to the NPOESS generation imagers. This paper summarizes the first evaluation of the MODIS surface reflectance product accuracy, in comparison with other data products and in the context of the MODIS instrument performance since launch. The MODIS surface reflectance product will provide an important time-series data set for quantifying global environmental change. (C) 2002 Elsevier Science Inc. All rights reserved.
