SSHCZO -- Soil Moisture -- COSMOS Probe -- Cole Farm -- (2018-2018)

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 0 (raw) data measured directly from COSMOS. The neutron count can be affected by various elements in surroundings, where hydrogen is often the dominant one (Zreda et al., 2012).

The COSMOS unit was installed on August 20, 2018. Soil samples for calibration were collected on September 4, 2018. Data are collected using Hydroinnova Cosmic-Ray Soil Moisture/Snow Sensing System. Data are transmitted via iridium satellite telemetry to the Hydroinnova servers on a hourly rate. Data are then transferred to the CZO database via CRON job that runs twice per day.
