SSHCZO -- Soil Moisture -- COSMOS Probe -- Garner Run (Sandstone Forested) -- (2015-2016)

Hydroinnova Cosmic-Ray Soil Moisture/Snow Sensing System (COSMOS), Model CRS-1000/B, non-invasively measures moderated neutron count among an averaged area (around 700 meters in diameter (Franz et al., 2013)), which can indirectly represent soil moisture in the top 50 cm of soil. This file includes level 1 data measured directly from COSMOS. The neutron count can be affected various elements in surroundings, where hydrogen is often the dominant one (Zreda et al., 2012). The neutron rate counted by the MOD column of COSMOS therefore can be used to determine soil moisture after a standard correction and point calibration, the results of which are COSMOS Level 2 and Level 3 data. Data collected using Hydroinnova Cosmic-Ray Soil Moisture/Snow Sensing System. Prepared to be corrected and be used to determine soil moisture.

Hydroinnova 宇宙射线土壤湿度/积雪探测系统（COSMOS），型号 CRS-1000/B，可非侵入性地测量平均区域（直径约700米，Franz 等人，2013年）中的中子计数，该计数可间接表征土壤表层50厘米内的土壤湿度。本文件包含直接从 COSMOS 测量的1级数据。中子计数受周围多种元素影响，其中氢元素通常占主导地位（Zreda 等人，2012年）。因此，COSMOS 的 MOD 列计数的中子率经过标准校正和点校正后，可用于确定土壤湿度，校正和校准的结果即为 COSMOS 的2级和3级数据。使用 Hydroinnova 宇宙射线土壤湿度/积雪探测系统收集的数据，已准备进行校正，以便用于土壤湿度测定。
