SnowEx20 Grand Mesa IOP BSU 1 GHz Multi-polarization GPR CMP Snow Water Equivalent, Version 1

This data set was collected during the SnowEx 2020 Intensive Observation Period (IOP) in Grand Mesa, Colorado. These data contain snow water equivalent (SWE) estimates. SWE is derived from Sensors & Software pulseEKKO PRO 1 GHz multi-polarization ground penetrating radar (GPR) two-way travel times.
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, IOP）。本数据集包含雪水当量（snow water equivalent, SWE）估算结果，该参数由Sensors & Software公司的pulseEKKO PRO 1 GHz多极化探地雷达（ground penetrating radar, GPR）的双向传播时间推导得到。
数据采集自格兰德梅萨密集观测期两处雪坑2N12与1S8周边的三个测点，关于该区域雪坑的更多细节可参见DOI: 10.5067/DUD2VZEVBJ7S。其中，雪坑2N12处的数据采集于修整后的雪地摩托道路（CMP1）、雪坑壁后方的新降雪区域（CMP2）以及SUSV履带车轨迹的右侧车辙（CMP3）；雪坑1S8处的数据则采集于SUSV履带车轨迹的右侧车辙（CMP1）、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）同样存档于美国国家冰雪数据中心（National Snow and Ice Data Center, NSIDC）。
