PETM（古新世-始新世极热事件）发生在距今约5600万年前，是新生代以来最强烈的一次全球快速升温事件。在此期间，大量轻碳（13C同位素含量较少的碳）从岩石圈释放到大气海洋系统中，造成了地球表层碳库中的碳同位素组分发生了显著的负漂。学者们认为PETM时期的碳释放触发了（或者至少加剧了）这次全球升温。PETM持续了大约20万年，其中碳释放持续的时间大约为1000-50000年。在千年到万年的时间尺度...
RELATIVE ERROR EVALUATION TO TYPICAL OPEN GLOBAL DEM DATASETS IN SHANXI PLATEAU OF CHINA
Relative error false slope ratio typical open global DEM datasets ICESat/GLA14 data Shanxi Plateau
2018/5/16
Produced by radar data or stereo remote sensing image pairs, global DEM datasets are one of the most important types for DEM data. Relative error relates to surface quality created by DEM data, so it ...
