Jornada Basin LTER: Wireless substation at NPP P-SMAL 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 P-SMAL substation located in center of 70m x 70m Jornada LTER NPP P-SMAL 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.

本数据集包含的土壤湿度（Soil Moisture）数据，采集自70m×70m的霍纳达长期生态研究（Long Term Ecological Research, LTER）NPP P-SMAL样地中心的NPP P-SMAL监测分站，该站点在10cm、20cm及30cm土壤深度处，每30分钟完成一次测定。
在新墨西哥州霍纳达LTER NPP样地开展的土壤体积含水量（soil volumetric water content）数据采集工作，可支撑霍纳达LTER监测计划的环境监测目标，该计划聚焦于植物-土壤水分动态过程。
本次监测同步每30分钟采集四类观测数据：土壤体积含水量、体积电导率（bulk electrical conductivity）、土壤温度（soil temperature）及体积介电常数（bulk dielectric permittivity）。
本数据集为持续更新的长期监测数据集。
