Vegetation Sampling

The vegetation teams were in charge of various measurements including destructive vegetation samples, spectral and leaf area data collection, dew samples, gravimetric soil moisture and surface roughness measurements. Vegetation water content (g of water per m^2) is an important parameter for modelling land surface emission at L-band and will be derived from destructive vegetation samples taken at several sampling locations. Moreover, surface spectral reflectance data is valuable in developing methods to estimate the vegetation water content and other canopy variables. Spectral observations made concurrent with biomass sampling will therefore provide the essential information needed for larger scale mapping using aircraft and satellite observations. In addition, reflectance measurements made concurrent with MODIS overpasses allow the validation of MODIS reflectance estimates based upon correction algorithms. During AACES, the Fieldspec3 developed by ASD has been used to make spectral measurements, and leaf area has been measured with a Licor LAI-2000.

Schematic of the vegetation sampling strategy

Vegetation samples for biomass, vegetation water content and surface reflectance/LAI measurements have been collected in 1km boxes which represent 1km resolution PLMR pixels. Within each box, the major vegetation types have been characterised by making measurements at a minimum of 3 sampling locations distributed within homogeneous crops/paddocks. The figure shown above illustrates the rationale of the vegetation sampling locations according to the 1km box classification and the major vegetation types. Vegetation samples were repeated for each vegetation type or maturity across the focus farm transect.
