GPM Ground Validation Airborne Snow Observatory (ASO) OLYMPEX V1

The GPM Ground Validation Airborne Snow Observatory (ASO) OLYMPEX dataset consists of snow depth, bare earth surface, land surface classification and a Red, Green, Blue (RGB) composite image, provided at 3 m spatial resolution during the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign held in the Pacific Northwest. These data were collected by a Riegl Q1560 scanning LiDAR and an ITRES CASI-1500 imaging spectrometer , both part of the NASA Airborne Snow Observatory (ASO), during two separate periods, February 8-9, 2016 and March 29-30, 2016. A previous September 2014 flight was used to obtain no-snow measurements used for deriving snow depth. The data are provided in GeoTIFF format.GPM 地面验证空中雪观测仪（ASO）OLYMPEX 数据集包括雪深、裸地地表、地表分类以及红、绿、蓝（RGB）合成的图像，这些数据以 3 米的空间分辨率在 GPM 地面验证奥林匹克山脉实验（OLYMPEX）野外考察期间提供，该考察在太平洋西北部进行。这些数据由 Riegl Q1560 扫描激光雷达和 ITRES CASI-1500 成像光谱仪收集，两者均为 NASA 空中雪观测仪（ASO）的组成部分，在两个不同的时间段内收集，分别为 2016 年 2 月 8-9 日和 2016 年 3 月 29-30 日。2014 年 9 月的一次飞行被用于获取无雪测量值，用于推算雪深。数据以 GeoTIFF 格式提供。
