CCZO -- Soil Moisture -- Hydroprobe -- Calhoun Critical Zone Observatory -- (2016-Ongoing)

Soil moisture data collected using a CPN 503 Elite Hydroprobe (Instrotek, Inc., Raleigh, NC, USA) inserted into 5 m deep wells lined with PVC tubing. Measurements are taken in 30 cm intervals at depths between 30 and 480 cm, measured from the mineral soil surface. Standard count (R) is collected once per sampling date before data collection. Counts are collected for 30 sec per sample. These data are collected concurrently with soil gas sample collections at three locations in the Research Area 1 cultivated fields, and in References Hardwood and Old Field Pine pairs in Research Areas 1, 4 and 7. Hydroprobe and soil gas data are also collected in 6 locations in a pine forest in Research Area 1. Calibration relating count data to soil moisture is still in progress.

本数据集收录了利用 Instrotek, Inc.（美国北卡罗来纳州罗利）生产的 CPN 503 Elite 水分探头采集的土壤水分数据。该探头被插入至由PVC管衬里的5米深井中。数据采集以30厘米的间隔，在自矿物土壤表面起30至480厘米的深度范围内进行。在数据采集当日，标准计数（R）仅在采样日期收集一次。每个样本的计数持续采集30秒。这些数据与土壤气体样本收集同步进行，采集地点位于研究区域1的三个位置，以及研究区域1、4和7的参考硬木和老林松树对。此外，在研究区域1的松树林中的6个地点也同时收集了水分探头和土壤气体数据。目前，正进行将计数数据与土壤水分相关联的校准工作。
