Summary
The 500 km wide swath of the right-looking ERS wind scatterometer and the orbital geometry allows measurement of the microwave backscatter of all the Antarctic region north of latitude 79°S. The values of the backscatter coefficient depend on the incidence angle and look directions of the antenna beams. Models of microwave backscatter which omit the azimuthal modulation (or directional anisotropy) introduce significant biases and temporal variations into the isotropic component of the backscatter. Use of these models is therefore likely to mask real physical variations due to changing surface conditions in areas where directional anisotropy is significant.
