SnowEx20 Grand Mesa IOP BSU Multi-polarization 1 GHz GPR CMP Travel-Times, Version 1

This data set was collected during the SnowEx 2020 Intensive Observation Period (IOP) in Grand Mesa, Colorado. These data contain the radar two-way travel times from a Sensors & Software pulseEKKO PRO 1 GHz multi-polarization ground penetrating radar (GPR). Data were collected at three locations around Grand Mesa IOP snow pits 2N12 and 1S8 (see DOI: 10.5067/DUD2VZEVBJ7S for more details on Grand Mesa IOP snow pits). Data at snow pit 2N12 were acquired on the groomed snowmobile road (CMP1), in the fresh snow behind the snow pit wall (CMP2), and in the right rut of the SUSV track (CMP3). Data at snow pit 1S8were acquired in the right rut of the SUSV track (CMP1), in the left rut of the SUSV track (CMP2), and in the fresh snow behind the snow pit wall (CMP3).
The raw version of these data (DOI: 10.5067/CL5ZRBCEF8G3) are also archived at NSIDC.

本数据集采集于美国科罗拉多州格兰德梅萨（Grand Mesa）2020年雪冰实验（SnowEx）密集观测期（Intensive Observation Period，简称IOP）。该数据集包含由Sensors & Software公司pulseEKKO PRO 1 GHz多极化地面穿透雷达（Ground Penetrating Radar，简称GPR）采集得到的雷达双向传播时间数据。数据采集点位覆盖格兰德梅萨IOP雪坑2N12与1S8周边的三处位置，关于格兰德梅萨IOP雪坑的详细信息可参见DOI：10.5067/DUD2VZEVBJ7S。雪坑2N12处的采集数据分别来自：修整后的雪地摩托道（CMP1）、雪坑壁后方的新降雪区域（CMP2），以及SUSV履带车轨道右侧车辙（CMP3）；雪坑1S8处的采集数据分别来自：SUSV轨道右侧车辙（CMP1）、SUSV轨道左侧车辙（CMP2），以及雪坑壁后方的新降雪区域（CMP3）。本数据集的原始版本（DOI：10.5067/CL5ZRBCEF8G3）同样归档于NSIDC。
