AVHRR Global 1K = Advanced Very High Resolution Radiometer Mosaics 1995 - 1996

The global land 1-km data set project represents an international effort to acquire, archive, process, and distribute 1-km AVHRR data of the entire global land surface in order to meet the needs of the international science community. A network of 29 high resolution picture transmission (HRPT) stations, along with data recorded by the National Oceanic and Atmospheric Administration (NOAA), acquired daily global land coverage from 1 April, 1992 through September 30, 1993, with the project subsequently extended through 1996. The six major participants (NOAA, ESA, USGS, NASA, CSIRO, and SMC) coordinate HRPT receiving stations to acquire and compile the data set. NOAA coordinates two HRPT receiving stations, Gilmore Creek, Alaska and Wallops Island, Virginia, and schedules the satellite's recorders to obtain local area coverage (LAC) AVHRR 1-km data over areas not covered by the other HRPT receiving stations. This collection of over 40,000 AVHRR images has been archived and made available for distribution by the United States Geological Survey, EROS Center and the European Space Agency.全球1公里分辨率陆地数据集项目是一项国际性合作工程，旨在获取、归档、处理并分发全球陆地表层的1公里分辨率高级甚高分辨率辐射计（Advanced Very-High-Resolution Radiometer，AVHRR）数据，以满足国际科学界的应用需求。 项目依托由29个高分辨率图像传输（High Resolution Picture Transmission，HRPT）站组成的观测网络，结合美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）记录的卫星数据，在1992年4月1日至1993年9月30日期间每日完成全球陆地覆盖数据采集，后续项目周期延长至1996年。 六家核心参与方（NOAA、欧洲空间局（European Space Agency，ESA）、美国地质调查局（United States Geological Survey，USGS）、美国国家航空航天局（National Aeronautics and Space Administration，NASA）、澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation，CSIRO）及SMC）协同各HRPT接收站，共同推进数据集的获取与汇编工作。其中NOAA负责协调两座HRPT接收站——阿拉斯加州吉尔莫克里克站与弗吉尼亚州沃洛普斯岛站，并调度卫星记录仪，以获取其余HRPT接收站未覆盖区域的局地区域覆盖（Local Area Coverage，LAC）级AVHRR 1公里分辨率数据。 本数据集累计收录超过4万幅AVHRR影像，已完成归档，并由美国地质调查局（USGS）地球资源观测与科学中心（Earth Resources Observation and Science Center，EROS Center）与欧洲空间局（ESA）对外提供分发服务。
