Description
Soil moisture measurements from the SWATS 10cm probe, STAMP 5cm probe, and 2.5cm deep EBBR, and SEBS probes at the SGP Central Facility are compared for a year (March 2016 through February 2017) to check for consistency, range, and precipitation response. The SWATS, STAMP, and EBBR are al located on the “hill”, within a maintained grassland. The SEBS is located in the agricultural area of the CF. The SWATS had a decreased range (25-37%) in comparison to the other instrument systems. The EBBR had a decreased range as well (22.5-35.5%). The SEBS exhibited a larger range (18.5-40%) than the EBBR and SWATS. The STAMP exhibited the greatest range (4-43%). All exhibited similar trends, with the SEBS being somewhat different in magnitude of the trends because of its location. The four systems responded similarly to significant precipitation events.
