Surface Roughness

Project Overview 

The four-quadrant paddock has been managed with different roughness and vegetation conditions during different periods for comparison. The furrows in quadrant 1 and 3 have been made perpendicular to the direction along with the radiometer footprint, while those in quadrant 2 are parallel to the footprint direction. This is designed to compare the roughness effects according to azimuth directions.
