At three locations in the ABoVE domain in-situ data loggers have been installed since summer 2017 to obtain time series data on soil moisture and temperature across a variety of land cover types, including tundra, boreal peatlands, and boreal uplands. The percent Volumetric Moisture Content (%VMC) as reported by the Campbell Scientific soil moisture probes is based on a loam mineral soil. Organic soils found across the ABoVE domain have a characteristic low bulk density and the default loam calibration typically underestimates actual soil moisture condition. To develop a calibration for organic soils, 42 tundra and 16 boreal soil samples have been extracted in the field to use in a laboratory setting to develop gravimetric based calibration algorithms (Bourgeau-Chavez et al. 2010).
