Abstract
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.
