NASA SnowEx Project

This data set provides 3 m gridded, bare-earth elevations (excluding trees) that are used as the baseline for the Airborne Snow Observatory (ASO) snow-on products. The data were collected during snow-free conditions as part of the NASA/JPL ASO aircraft survey campaigns....本数据集提供3米分辨率的网格化裸地高程数据（已剔除树木影响），作为机载雪观测站（Airborne Snow Observatory, ASO）积雪覆盖状态产品的基准数据。该数据采集于无雪时段，属于美国国家航空航天局（National Aeronautics and Space Administration, NASA）/喷气推进实验室（Jet Propulsion Laboratory, JPL）ASO机载测量航次的组成部分。
