OpenAltimetry

OpenAltimetry is a cyberinfrastructure platform for discovery, access, and visualization of data from NASA’s ICESat and ICESat-2 missions. These laser profiling altimeters are being used to measure changes in the topography of Earth’s ice sheets, vegetation canopy structure, and clouds and aerosols. A new paradigm for data access was required to serve the needs of a diverse scientific community seeking to take advantage of these unique observations. OpenAltimetry, which is the product of a collaboration between UNAVCO, the National Snow and Ice Data Center (NSIDC), the Scripps Institution of Oceanography and San Diego Supercomputer Center at UC San Diego, was custom-built to meet these needs.OpenAltimetry是一款科研网络基础设施平台，可为美国国家航空航天局（NASA）ICESat与ICESat-2任务的数据提供发现、获取与可视化服务。上述任务搭载的激光剖面测高仪（laser profiling altimeters）可用于监测地球冰盖地形、植被冠层结构以及云层与气溶胶的变化情况。为满足多样化科研群体利用这些独特观测数据的需求，亟需构建一种全新的数据获取范式。OpenAltimetry由加州大学圣迭戈分校（UC San Diego）下属的联合大学大地测量与地球物理合作协会（UNAVCO）、国家冰雪数据中心（National Snow and Ice Data Center，NSIDC）、斯克里普斯海洋研究所以及圣迭戈超级计算机中心联合研发，专为满足上述需求量身打造。
