AMC

The Ameriflux Measurement Component system (AMC) comprises 12 soil temperature and volumetric water content (VWC) reflectometers and a set of upwelling and downwelling photosynthetically active radiation (PAR) sensors, all deployed within the fetch, or range, of the eddy correlation flux measurement system. Soil temperature and VWC sensors placed at two depths (10 and 30 cm below the vegetation layer) at six locations or microsites allow soil property inhomogeneity to be monitored across a landscape.
