MODIS Mosaic of Antarctica 2008-2009 (MOA2009) Image Map

Abstract: The MODIS Mosaic of Antarctica 2008-2009 (MOA2009) Image Map consists of two cloud-free digital image maps that show mean surface morphology and a quantitative measure of optical snow grain size on the Antarctic continent and surrounding islands using 260 orbit swaths from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on board the NASA EOS Aqua and Terra satellites.

摘要：2008-2009年南极MODIS镶嵌图（MOA2009）影像图集由两张无云数字影像图构成，该图集利用搭载于美国国家航空航天局（NASA）地球观测系统（EOS）Aqua与Terra卫星上的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）所获取的260轨扫描幅宽数据，呈现了南极大陆及周边岛屿的平均地表形态，以及光学雪粒尺寸的定量测量结果。
