A MODIS Receiving Station at the University of Alaska Fairbanks

该项目将在阿拉斯加费尔班克斯大学（UAF）建立一个中分辨率成像光谱仪（MODIS）接收站。 中分辨率成像光谱仪是去年发射进入极地轨道的Terra卫星上的仪器之一;另一个中分辨率成像光谱仪将于明年12月伴随Aqua卫星进入轨道。 这些大范围遥感仪器的光谱范围很广，从可见光到热红外波长，旨在观测和监测陆地、海洋和大气层内的全球变化。 中分辨率成像分光仪使用直接存取系统提供直接与用户的通信联系。 该系统依赖于分布式接收站来收集其接收掩码中的实时数据。 UAF是接收、处理、存档、使用和分发北方高纬度地区MODIS数据的理想场所。 从费尔班克斯开始，一个接待面具将覆盖阿拉斯加的所有陆地和海洋领土，并跨越整个北极地区的相当大一部分。 中分辨率成像光谱仪科学小组已经开发并验证了一套算法，可以从卫星测量数据中自信地提取各种表面和大气特性。 当与其他属性相结合时，这些数据应该提供一种强有力的手段来处理对国家具有科学、社会和经济重要性的问题。 阿拉斯加大学费尔班克斯中分辨率成像光谱仪站将有四个主要目标。 这些是：（1）提高研究人员的能力，以帮助解决北极全球变化问题;（2）增加遥感和卫星图像分析方面的教育机会;（3）协助州和联邦机构以及阿拉斯加土著公司清点和监测陆地活动（火山爆发、森林火灾、大气污染物等）。（c）海洋和海洋（石油溢漏、海洋生产力、海冰迁移等）;以及（4）向私营部门提供对MODIS数据的便利、实时和低成本访问，以鼓励阿拉斯加遥感产业的发展和扩大（能够向其客户销售、处理和分发卫星图像信息）。

This project will establish a Moderate Resolution Imaging Spectroradiometer (MODIS) receiving station at the University of Alaska Fairbanks (UAF). MODIS is one of the instruments on board the Terra satellite launched into polar orbit last year; another MODIS will accompany the Aqua satellite into orbit next December. These wide range remote sensing instruments, which span a wide spectral range from the visible to thermal infrared wavelengths, are designed to observe and monitor global changes on land, sea, and within the atmosphere. MODIS uses a Direct Access System to provide a direct-to-user communication link. This system relies upon distributed receiving stations to gather real-time data across their reception masks. The UAF is the ideal location for receiving, processing, archiving, using, and distributing MODIS data across the high northern latitudes. From Fairbanks a reception mask will cover all the land and sea territories of Alaska and span a considerable portion of the whole Arctic Region. The MODIS Science Team has developed and validated a suite of algorithms to confidently extract various surface and atmospheric properties from the satellite measurements. When combined with additional properties, these data should provide a powerful means of approaching issues of scientific, social, and economic importance to the state. The University of Alaska Fairbanks MODIS station will have four main objectives. These are: (1) to expand capabilities for researchers to contribute in solving arctic global change problems; (2) to enhance educational opportunities in remote sensing and satellite image analysis; (3) to assist state and federal agencies, as well as Alaskan Native Corporations, in inventorying and monitoring activity on land (volcanic eruptions, forest fires, atmospheric pollutants, etc.) and sea (oil spills, ocean productivity, sea ice migration, etc.); and (4) provide expedient, real-time, and low-cost access to MODIS data to the private sector in order to encourage development and expansion of remote sensing industry in Alaska (capable of marketing, processing, and distributing satellite image information to their customers).
