BOREAS HYD-06 AIRCRAFT GAMMA RAY SOIL MOISTURE

This data set contains percent soil moisture (by weight) (and/or water content if there is a moss/humus layers measured from aircraft using a terrestrial gamma ray instrument. There is also data that indicates the location of the aircraft at the time it collected the terrestrial gamma ray data for the various flight lines and bins. The location information contains a list of coordinates that indicate the path of the aircraft for each bin. The data were collected during four time periods from September 1993 to September 1994 over the Southern Study Area (SSA) and two time periods from February to August 1994 over the Northern Study Area (NSA).本数据集包含以重量计的土壤含水率，若存在苔藓/腐殖质层时也可指代含水量，该数据通过搭载于航空器的地面伽马射线仪器实测获取。本数据集同时包含各飞行航线与数据分箱在采集地面伽马射线数据时的航空器位置信息，该位置信息包含对应每个数据分箱的航空器飞行路径坐标列表。本次数据采集覆盖两个研究区域：南部研究区（Southern Study Area, SSA）的采集时段为1993年9月至1994年9月，共4个时间段；北部研究区（Northern Study Area, NSA）的采集时段为1994年2月至8月，共2个时间段。
