ABoVE: Study Domain and Standard Reference Grids, Version 2

The Arctic - Boreal Vulnerability Experiment (ABoVE) has developed two standardized spatial data products to expedite coordination of research activities and to facilitate data interoperability. The ABoVE Study Domain encompasses the Arctic and boreal regions of Alaska, USA, and the western provinces of Canada, North America. Core and Extended study regions have been designated within this Domain and are provided in a vector representation (Shapefile), a raster representation (GeoTIFF at 1,000-meter spatial resolution), and a NetCDF file. A standard Reference Grid System has been developed to cover the entire Study Domain and extends to the eastern portion of North America. This Reference Grid is provided as nested polygon grids at scales of 240, 30, and 5-meter spatial resolution. The 5-meter grid is new in Version 2. Note that the designated standard projection for all ABoVE products is the Canadian Albers Equal Area projection.

北极-北方地区脆弱性实验（ABoVE）已开发出两种标准化的空间数据产品，旨在加速研究活动的协调并促进数据的互操作性。ABoVE研究域覆盖了美国阿拉斯加的北极和北方地区，以及北美加拿大西部省份。在此研究域内，已指定核心和扩展研究区域，并以矢量表示（Shapefile）、栅格表示（1,000米空间分辨率的GeoTIFF）和NetCDF文件的形式提供。为覆盖整个研究域并延伸至北美东部地区，已开发了一种标准参考网格系统。该参考网格以嵌套多边形网格的形式提供，尺度分别为240米、30米和5米空间分辨率。5米网格在版本2中为新增内容。请注意，所有ABoVE产品指定的标准投影为加拿大阿尔伯斯等面积投影。
