Jornada Basin LTER: Wireless substation at NPP C-GRAV site: 30-minute soil volumetric water content data: 2013 - ongoing

30-minute Soil Moisture data is measured at 10cm, 20 cm, and 30 cm soil depths at the NPP C-GRAV substation located in center of 70m x 70m Jornada LTER NPP C-GRAV site. Collection of soil volumetric water content data at Jornada LTER NPP sites, New Mexico, supports the environmental monitoring objectives of the Jornada LTER monitoring program that look at plant-soil water dynamics. Volumetric water content, bulk electrical conductivity, soil temperature, and bulk dielectric permittivity are measured every 30 minutes. This is an ONGOING dataset.

本数据集为30分钟采样间隔的土壤湿度监测数据，采集于美国新墨西哥州约纳达（Jornada）长期生态研究（Long-Term Ecological Research, LTER）NPP C-GRAV样地（面积70m×70m）中心的NPP C-GRAV监测分站，采样土层深度分别为10cm、20cm与30cm。本次采集的土壤体积含水量（soil volumetric water content）数据旨在支撑约纳达LTER监测计划中针对植物-土壤水动力学的环境监测目标。该数据集每30分钟同步采集四类参数：土壤体积含水量、体积电导率（bulk electrical conductivity）、土壤温度（soil temperature）与体积介电常数（bulk dielectric permittivity）。本数据集为持续更新的长期监测数据集。
