  • Abstract
    Enhanced resolution images made from QuikSCAT data use two different forms of the single-variate Scatterometer Image Reconstruction (SIR) algorithm: for egg sigma-0 measurements the SIR algorithm is used while for slice sigma-0 measurements, the SIR with filtering (SIRF) algorithm is used. For egg measurements the full antenna/processing spatial response is used while a simplified spatial response function in which the spatial response is assumed to be 1 over the footprint and 0 elsewhere is used for slice measurements. The SIR algorithm with eggs makes images of sigma-0 at the measurement incidence angle on an 4.5 km pixel grid. The effective resolution varies depending on region and sampling conditions but is estimated to be 8-10 km in most areas. The SIRF algorithm with slices makes A images at 2.225 km pixel spacing with an estimated effective resolution of 6-8 km. Slice measurements are much noisier than egg measurements.
