中分辨率成像光谱仪(MODIS)是一种地球观测传感器，计划作为地球观测系统(EOS)的设施仪器，计划于1990年代中期开始运行。MODIS由两个相互支撑的传感器组成，覆盖的带状宽度足以从一个极地轨道、太阳同步、可维修的平台提供几乎完整的两天全球覆盖。要提供高信噪比，例如，在光谱频带的动态范围内进行10-12位量化时，信噪比为500比1或更大。MODIS的寿命预计为十年左右。其中一个MODIS传感器被命名为MODIS-N，其中N代表最低点。与MODIS-N相伴的是MODIS-T，其中T表示可倾斜的视场。讨论了MODIS设施从概念设计研究(A阶段)到详细设计研究(B阶段)的发展。
The moderate resolution imaging spectrometer (MODIS) is discussed as an Earth-viewing sensor that is planned as a facility instrument for the Earth Observing System (Eos) scheduled to begin functioning in the mid-1990s. The MODIS is composed of two mutually supporting sensors that cover a swath width sufficient to provide nearly complete two-day global coverage from a polar-orbiting, sun-synchronous, serviceable platform. High signal-to-noise ratios are to be provided, e.g. 500 to 1 or greater with 10-12-bit quantization over the dynamic ranges of the spectral bands. MODIS' lifetime is expected to be about ten years. One of the MODIS sensors is termed MODIS-N, where N signifies nadir-viewing. The companion to MODIS-N is MODIS-T, where T signifies a tiltable field-of-view. The development of the MODIS facility from conceptual design studies (Phase-A) into detailed design studies (Phase-B) is discussed.<>
